Guys, I have also received my pre2. It sounds amazing! I was previously using my integrated as a pre but this sounds much better (as it should of course compared to an integrated). Bass is amazing as is the space/air.

I have one concern though which has probably nothing to do with the pre. I was adjusting my all cables in the back and once I turned my 225 amp on after I finished all the cabling, there was a huge, very loud cracking sound from my speakers. I was afraid I blew everything up but luckily everything is fine.

The cables were properly connected. Was there perhaps anything in the order that I turned on the devices? Or is this the DC-thing of the 225? Hope someone can help me out as I'm afraid to touch anything now :-) Any help is highly appreciated (don't want to hijack the thread though).
 
Sources first, then preamp, then amp last. Amp off first, then pre, then sources. Something could have been loose or interfering with the cables. With everything off, check that all is tight then tun all back on in the correct order. Enjoy!
 
thinking of recommending the Job 225 to my brother just to see if it will work better than his Krell KAV 250a with his setup. He's using MicroOnes (like me) and source would be direct from Audio Aero Prima DAC (which is the DAC from the Capitole). Has anyone ever heard the Job and the KAV 250a by any chance?
Best regards

I have MicroOnes and they work well with the Job 225. I have posted a video with Job 225 and MicroOnes here. Check out the Job Pre2 thread.. the video says very little but hope u can hear transperency and musicality of Job.

I recommend that setup.

thanks for answering. nice to know that someone else is happy with the combination of both. do you feel that the current in the Job is enough for the MicroOnes. I'm under the impression that current is more important than power in their specific case. May I ask what the rest of your system is?
best regards

Yes, its completely fine. I completely recommend pairing it up together.

Rest of my system is:

Chord Hugo -> Job 225 -> MicroOnes

AQ Rocket 88 speaker cables/ AQ Vodka Digital Optical/ AQ Cinnamon ICs/ Shunyata Venom 3 Powercord

Picking up Job Pre2 sometime next month so itll be in the chain soon :)


Its really a good match between microones and job pre2 and youll love it.

Hi Folks

I'm new to this forum, but I have been following this thread with interest for a while. This week I ordered a JOB 225 amplifier. It's been in my system for a few days and my initial impression is that it's a very good amplifier for the money.

However I have one concern, I don't know if anyone else has experienced the same as me, but the amplifier vibrates slightly in tune with the music being played. My guess is that it's the power transformer. It does it at quite low volumes into my Living Voice OBX-R2 speakers (94dB/1 watt/1M).

I'm sure this is not a good thing, I've seen it before with some valve amplifiers, but never with anything solid state.

I'd be interested if anyone else has noticed any vibration from their JOB 225 when playing music?
 
The Job 225 saves money by having an inexpensive folded steel painted case. This does buzz in time with the music, but it is airborne and structure borne sound which is causing that, not something in the amp.
How do I know? Mine vibrates in time with music played in the room even when it is switched off.

Probably nothing to worry about IMO.

Thanks for your thoughts Frank. It's interesting as the Job amplifier is only about 4" above floor level on a low rack well behind the speakers.

My first thought was that it must be airborne induced vibration, but it's evident that nothing else in the rack is affected in any way, even the rack where the amp sits is free of vibration, it's just the amp case I can feel vibrating.

You could always add some sound dampening sheets to the metal.

Exactly like mine.
Mine is on the marble bottom shelf of a very solid GM rack. Nothing else on the rack vibrates either, and since I have two music systems in the room, don't ask, I can be sure that it is the sound causing the vibration since it is there when playing the other system with the Job 225 switched off.
Anyway, if you want to worry about it, feel free ;)
 
Hey guys, I want to thank you all for the invaluable information I have been able to gather regarding the Job 225. I appreciate your site here, and feel fortunate to have discovered it a week ago in my quest for audio knowledge. I see a wealth of ownership of some highly regarded gear by many of you, so opinions concerning some pairings would be taken with great consideration. I am attempting my first decent system in 20 years so bear with me on my lack of experience. I really like the idea of the Job mono amps, based on how AS members enjoyed the 225's sound. Does anyone know how they might compare sonically with what many feel is one of the best Class D amps, the Spectron Musician III? I am also looking at the PS Audio Direct Stream DAC, and would welcome any experiences with its sound characteristics. Publications have claimed it extracts more sound information from source than any other DAC. I am not sure about speakers yet, but I have a fondness for ML, Maggies, etc smoothness and speed but always miss the slam of drivers. Can't have it both ways? Would the Jobs be up to task with speakers where the impedance can drop so low? Thinking Mono's would cure the difficult load problem, am I thinking this wrong? Thanks to all, and I look forward to adding, and gaining any info experiences to share. Thanks

In my experience, I would not say that the DStream Dac is the most detailed out there. Its a good Dac, but definitely not my favourite. If Detail is what you seek over all else, I would suggest the Phasure Nos1a, Meither, top MSBs, etc. However, you may find that after listening to many Dacs you come to value musicality, naturalness, ease of listening, etc...other qualities that other Dacs excel at.

I use a tube Dac (Lampizator), so I am biased in that direction. Good things are said about other Dacs too liike MSB analog, Auralic Vega, Lumin Dac/Streamer, Bricasti, Antelope Platinum, Empirical Audio Overdrive SE dac, Aesthetix Pandora Dac, Ear Yoshino Dacute 4, Audio Note Dac 4, Chord Hugo and QBD, Ayre QB9 DSD, etc.

It also depends on if you LOVE DSD, so as to get a Dac that does it well....while still doing great PCM.

Never heard the Spectrons, but have heard a few Class D amps. I think the Job monos should be able to beat them, if you like the more classic amp sound. I will hear the Monoblocs likely next week and will be able to say. Goldmund makes very good amps, that is certain. At double the power of the 225, they should be able to hadle the Maggie (known power hogs) easily.

I myself use Heil AMT accordian style folded ribbons (air velocity transformers) as I love the airy openness of the mid/HF with them. I attach a picture of my 2 pairs running in a perfectly phase coherent manner...

Hello, welcome to the forum. I have rather difficult to drive speakers that are regarded by many to be power hungry speakers. EA MicroOnes . The Job 225 drove them perfectly fine. I think you would be fine with the Maggies.

As far as pairing the Job 225 without a preamp in the mix like the Job Pre2, I would stay away from Directstream and the Auralic Vega. There was a member here who have had problems with direct connection for Directstream to Job 225, and the Auralic Vega runs hot, I have personally inquired the designer of Vega pairing it with Job 225, and he advised not to do so. When I had my Job 225, I paired it with the Chord Hugo and got OK results. The soundstage was a bit flat without a preamp in the mix, but it was very musical nontheless.

For a DAC, I have heard the Lampi Big 7 at a show paired up with Wells Audio innamorata and was blown away. I wouldn't know how it would sound with the Job 225, but I think it would be a great match if you get get the Lampi 7 customized in gain for the Job 225. One thing I can say about Job 225 is that it's very transparent and have excellent detail in bass, so I think it's safe to assume a tube DAC/Pre like the Lampizator would be a great match giving you that musicality without any harshness.
