    Job 250 monos amps: absolutely wonderful ...

    After thinking about these amps for the better part of a year and a half, I could not resist any longer.

    Not even broken in, they are amazing. These 250 monos are absolutely great. Solid build quality, surprisingly heavy with that distinctive sweet and fast Goldmund sound. They have better bass and more air, simply wonderful and a true high end bargain in the audio world.

    Re: Job 250 monos amps: absolutely wonderful ...

    THE JOB 250
    A Professional Ultra-High Speed Mono Amplifier
    The latest addition to the JOB amplifiers family is the mono version of the family.
    The JOB 250 is a Mono block of 250W in a reasonably small chassis, only slightly higher than the JOB 225.
    Totally protected, easy to use, perfectly silent, it is THE amplifier for an audiophile who is conscious of his budget but demanding the absolute best of the world in sonic quality and having speakers very demanding in power.
    With its extraordinary dynamic capability and its unconditional stability, it can drive anything.
    More, with the JOB proprietary "Ultra-Control" of the drivers, any speaker even a large one will sound better when used with the JOB 250.
    With extremely low distortion, especially IM distortion, literally zero group delay distortion, ultra-wide MegaHerz bandwidth and DC coupling, extreme silence and cool operation, it can be played at high level with the same impression of ease than at low levels.

    Thanks to the JOB Electronics large scale of operation on power amplifiers, the JOB 250 is also offered at a realistic price, where high-end audio manufacturers would charge $6'000 to $15'000 if the same amplifier were sold through the traditional channels.

    Re: Job 250 monos amps: absolutely wonderful ...

    Joe - I just saw a posting on JOB's Facebook page with some customer feedback on these amps. I'm assuming it came from you. These have been on my radar for a while now...I would love to hear them someday as they appear to be right up my alley in terms of sonic signature. Fast, detailed, yet sweet on top.

    Re: Job 250 monos amps: absolutely wonderful ...

    Yes, that was me. I've been a Job fan from the beginning. These are everything good about the stereo amp and INTegrated but MORE! I can't afford Goldmund, but these are a bargain and ship pretty much overnight, once the order is processed.

    All my Job gear and especially these monos will NEVER leave my system.

    I don't think you will be disappointed.

    Joe, what do you recommend for a preamp with these monos?

    Re: Job 250 monos amps: absolutely wonderful ...

    I'm sure the STP-SE would be superb. My BHK preamp sounds amazing with it but that preamp is a little quirky. I get a soft pop through the speakers with every volume step change on almost every amp I use with it. Of course my KXR20 is freaking awesome with it.

    Re: Job 250 monos amps: absolutely wonderful ...

    Congrats Joe. I am sure its a winner. Some folks reported that the soft pop is lot less through the balanced output than the single ended. You can try the balanced output of the BHK, though you might run into too much gain with the Jobs. I guess the intensity would also depends on the speaker sensitivity. I run balanced to the Nords and the pop is so low in intensity that it doesn't bother me....

    Re: Job 250 monos amps: absolutely wonderful ...

    These are another on my consideration list. I really liked the 225 that I had. I think it was a little too early in my "rebirth" into the audio world to truly appreciate it. I would love it if Goldmund offered the Job in black face ...

    I think the First Watt is similar in sound signature, only much more detailed. The other real difference is power... and gain... the First Watt is on the extreme low gain while the Job is on the extreme high end (Rothwells help a lot)...

    By the way, Gratz Joe... like you needed another amplifier ...

    Re: Job 250 monos amps: absolutely wonderful ...

    Randy there is always Krylon if you have to have black face or you could have it done at an auto body shop or powder coated. I prefer black too but the Job doesn't stick out as much as standard silver.

    Re: Job 250 monos amps: absolutely wonderful ...

    Rob

    I had good luck with the Job and the STP-SE but a tube preamp with low gain would be ideal unless you are willing to use the Rothwell Attenuators which I have with the Modwright. I am curious about the Backert Labs Rhumba 1.2 whose standard is 9db gain, but since you order straight from the factory I feel sure Andy could lower it if you needed. Something around 6 db or a little lower would be ideal.

    Re: Job 250 monos amps: absolutely wonderful ...

    Randy - the JOB and F6 might both be sweet, but FAST is probably one of the last words I would use for the F6.
    The Clones Audio 25pm monos I had for a while...now THOSE were fast. It sounds to me like JOB really captures the best of both worlds.

    Re: Job 250 monos amps: absolutely wonderful ...

    I don't know the F6 but the Job 250 monos, especially, are fast and sweet. Open, airy, ballsy and clean. They don't have a tremendously thick tone but, damn, I don't miss it one bit. They play like much more expensive amps and have the characteristic Goldmund sound.

    Re: Job 250 monos amps: absolutely wonderful ...

    Joe

    From what I have read the F6 sound would be akin to the Pass 30's of one generation or the other. For using the BHK with the Mono's, did engaging the Mute before changing volume eliminate the click?

    Re: Job 250 monos amps: absolutely wonderful ...

    Hi Jack,

    Muting before volume change absolutely works but it becomes a guess as to where I want to be volume wise. It's sort of a quick and dirty trick to get around the clicking.

    Thanks for the suggestion.

    Re: Job 250 monos amps: absolutely wonderful ...

    Joe

    Is the match of the two enough to overlook the clicking? I would think the gain would be about perfect so it all comes down to the sound of the pair together versus the click.

    Re: Job 250 monos amps: absolutely wonderful ...

    Thank you Nikhil.

    Playing right now with the PS Audio BHK preamp. Just a great, great combination.

    Re: Job 250 monos amps: absolutely wonderful ...

    Yes, it's only a soft pop and sometimes if I change many steps, it only pops once or twice, maybe a few times. The BHK is a keeper regardless.

    A smaller cost if you, or I, didn't have Strads in the first place and probably decent performance.

    Re: Job 250 monos amps: absolutely wonderful ...

    The ELAC's offer similar price to performance ratio as the JOB. I don't think anyone would typically pair $45,000 Speakers with a $2k amp. Joe's Ayre monos fits the bill for that pairing.

    I was thinking how nice the ELAC/JOB pairing would be for not a lot of $$.

    But what preamp?
    Hmmm...

    Re: Job 250 monos amps: absolutely wonderful ...

    The BHK is awesome, the STP-SE would definitely be great, Ayre KX5-20 would be a combo I'd love to try, Backert Labs is another I'd like to hear. Oh, and the Primaluna pre would be awesome too.

    Re: Job 250 monos amps: absolutely wonderful ...

    Joe

    Terry London tested the Backert against the PrimaLuna HP and said it wasn't even a contest. He likened it to his EAR preamp at many times the cost. As the Backert's are built to order only a few miles from you by a master "modder" and repair tech I am sure the standard 9 db gain could be adjusted with the order. Tube preamps have normally high gain unless you buy from one of the smaller companies. The Aesthetix preamps have adjustable gain but like AI preamps of old only seem to like certain tubes. The safe bet for any amp with input sensitivity numbers like the Job is always going to be the STP-SE unless you want the stark truth of a pure passive like the Luminous, Hattor or others. Based on the Goldmund pedigree I don't think the Job mono's would be out of place in a pairing with the Magico S3, Vandersteen Quatro CT, Focal Sopra or the appropriate Raidho or Dali. I am going to break my 225 back out again in honor of Joe's purchase and see how they fair with the KO's.

    Thanks for the background info.

    I am sure the 225 on the KO's will be killer. I love Nola speakers and I am positive it will be a great match.

    You have a good point as the Job225 was my favorite amp on the Raidho D3's.

    Re: Job 250 monos amps: absolutely wonderful ...

    I don't get how a pair of 10kg mono's under $3.5k can push out those numbers without employing a class D topology? That makes my 42kg integrated seem bloated, and overweight by comparison . Does anyone know if Jenny Craig accepts amplifiers as new members? .

    Re: Job 250 monos amps: absolutely wonderful ...

    The Job mono amps are almost 23 lbs. each. Certainly a lot heavier than the Job 225 or INTegrated which I assume means a beefier power supply. There's also a bigger heat sink on the amps which to me means business

    Overall a terrific deal in my book and they feel like they will last a lifetime.

    Re: Job 250 monos amps: absolutely wonderful ...

    Joe, the Job mono's look well designed & have a beefy psu. They do indeed look like a very good deal like the Ascend Acoustics Sierra-2 bookshelfs I mentioned earlier. Just out of curiosity I checked the weight of my first integrated amp back in 1991, Nakamichi Amplifier 1 (see below) which tips the scales at 15kg & was rated @80 watts into 8 ohms. All I can say is those amps performs magic tricks like Houdini on crack! .

    I had a Nakamichi with a Stasis amplifier. That was a great little amp no doubt. Nelson Pass certainly made a fine amplifier back then (as he does now)!

    I think the First Watt is similar in sound signature, only much more detailed. The other real difference is power... and gain... the First Watt is on the extreme low gain while the Job is on the extreme high end (Rothwells help a lot)...

    By the way, Gratz Joe... like you needed another amplifier ...
    Randy, are you saying the Firstwatt is more detailed than the Job?

    I have a F7, and have been thinking about getting a 225 or the monos now.

    Re: Job 250 monos amps: absolutely wonderful ...

    Unless your speakers are very easy to drive, definitely GET the 250 monos. Waaaaay better in all respects.

    I know it's twice the price but more like 6 times the performance.

    Re: Job 250 monos amps: absolutely wonderful ...

    In my opinion, the First Watt is a more detail amplifier being that it is Pure Class A. However, and a big however is that it is very low powered, especially the F7. The F6 is the most powerful FW. The limitations are pretty much in that they cannot drive the systems extremely loud and hard to drive speakers they may not be able to get to acceptable levels. This is not an issue for me because the F6 gets my hard to drive speakers plenty loud enough for me. Many people would require more power.

    I have been considering a larger amplifier, such as possibly a larger ARC, or PrimaLuna or possible the Job mono blocks mainly for the possibility of going to a different speaker down the road. Something like a KEF Reference for example.

    But for me, the JOB 225 was great, and had a lot of power. The only real draw back was that it is very high gain so something like the Rothwell Attenuators was a requirement to achieve any kind of volume control from my Pre-amplifier. In absolute purity I do prefer the First Watt, but the JOB if very good and very acceptable. So if more power is needed, they can't be beat!

    Re: Job 250 monos amps: absolutely wonderful ...

    Randy

    The STP-SE was the only preamp I tried other than the Nuprime DAC-10 that didn't have a gain issue with the Job 225. The Nuprime just happens to have a similar volume control circuit to the W4S. All the others required the Rothwell's for any volume control flexibility. It would be one of the reasonable priced options with the Job unless something like a Luminous or Hattor works for you. With only a couple of hundred dollars difference at MSRP I would find it hard to justify the Job preamp instead. Plus no upgrade path for the Job.

    My speakers are 91 db efficient, 6 ohm, and use a simple series crossover...yet my F7 has a difficult time with them. I switched to my old Monarchy Audio SM70's and they sound MUCH better on them. Particularly more detailed and more lifelike.

    This makes me wonder if my F7 needs some attending to.

    As far as the Job goes, I don't really need the power they have, but I've read that the clarity and speed are outstanding. I use a TVC passive preamp, so it would seem that they'd be ok, as far as volume control.

    Re: Job 250 monos amps: absolutely wonderful ...

    When I had my JOB I was using a McIntosh, and then the STP-SE. The Rothwell's helped. But again, too early in my re-evolution...

    It sounds like your F7 has an issue... which Nelson said he has never had.... 100% reliable. My speakers are extremely hard to drive compared to yours. My F6 gives me great sound and plenty of volume. My ARC gets a bit louder. Also, the First Watts are very low gain, so you have to push the volume control a bit more than other amplifiers...

    From my listening experience F6 is better than F7. I found the F7 somewhat lifeless compared to F6

    This makes me wonder if my F7 needs some attending to.

    As far as the Job goes, I don't really need the power they have, but I've read that the clarity and speed are outstanding. I use a TVC passive preamp, so it would seem that they'd be ok, as far as volume control.
    Great amp & very underrated...not surprised it beats the F7...get it checked if you like...but bet I am right...

    I have never listened to the F7, but I know from speaking with Nelson that he only adds a new model when he feels the design is worthy of the First Watt name. With that said my F6 is a great sounding amplifier but I am also intrigued with the JOB mono blocks moving forward.

    Currently I do not need the extra power, but down the rad if I want to move into a different speaker I might.

    Re: Job 250 monos amps: absolutely wonderful ...

    My Job 250 monos are great. Destination amps. I've been playing them on my Strads and while I love and could easily live with the Job INTegrated, the 250 monos are just a heck of a lot better in all respects compared to a lot of other amps that I've heard. They have both XLR and RCA inputs and so far sound great with my BHK preamp, they are incredible with my KXR Twenty preamp. I know that is an unusual pairing but any decent preamp will be great. Air, 3D, articulate bass, sweet vocals, big soundstage and dead quiet makes these amps almost perfect. I love these and they are not going anywhere.

    Hi Joe,

    Seems that you have recently bought a pre2 as well. How is the performance of pre2 + 250 combo? I wonder if the JOB combo makes the sound more coherent than using other preamp in the chain.

    Hi Rubato,

    Welcome to the forum. Thank you for joining.

    I am a big Job Electronics fan from the beginning. Like I've said before, the 250 monos are absolutely amazing. The Job Pre2 is a solid performer and depending on your taste or preference, could be great. I prefer a preamp (typically tube but not absolutely necessary) that adds a little warmth and bloom. The Job 250 monos are fast and clean, but in a really good way. Adding a little warmth, sweetness or bloom just makes perfection to me at an amazing price. I believe that if you have overly warm speakers, the Pre2 and any Job amp will be great. If your speakers are a little tougher to drive or you just want a little better performance, the Job 250 monos are just right. Assembling a system is like a really good recipe, add seasoning to taste - to make it your own. If your sources are warmer or sweeter than the Job Pre2 will be great. My preference is for a slightly better sounding preamp.

    Re: Job 250 monos amps: absolutely wonderful ...

    Thanks Joe! That's informative and helpful.
    One more question, I wonder if 250 monos are better in all aspects than 225? I have a pair of Reference 3A de capo, very easygoing (92db, 8ohm). I am currently using a 30W DIY amp but considering an upgrade. I understand 225 is good enough for the purpose, but if the monos do not overdrive sensitive speakers in general, it may be a good investment so that I have more options when upgrading the speakers later.

    Hi,

    If you don't mind spending twice as much for the Job 250 monos, they are an absolute upgrade able to drive a much wider variety of speakers and do it much better like I describe in my previous post. The monos are way more versatile and the sound quality is better in every respect. I feel that even the amp portion of the Job INTegrated, sounds better than the 225 and the 250 monos better everything below them.
