Job 250 monos amps: absolutely wonderful ...

Are you using SE or Balanced IC's between the Music First and the Job mono's? If the former try swapping to XLR cables and see if it goes away.
 
Must have built your home at the wrong spot [emoji6]

Synology NAS, LPS-1, microRendu, Job INTegrated, Penaudio Cenya.

Actually, I was using XLR cables but have come to the conclusion that it needs to be RCA. I bought a XLR-RCA adapter and the noise went away, I've double-checked today, if I remove the RCA adapter noise comes back. Unfortunately I had my Baby Classic built in a minimal way to only have XLR in- and outputs. I need to check with Jonathan if he can modify it for me without it costing a fortune...

I suspect that my "microphonic" Lampi is the source of the problem though.... would be interesting to try with a solid state DAC, but I don't have any spare on the shelf....
 
Hmmm... from my understanding XLR should be less susceptible than RCA interconnects to hum and noise, not more. Please correct me if I am wrong on this one.

The only reason I use RCA is if the equipment does not have XLR (such as my First Watt amplifier).
 
I don't know anything anymore, I've started hearing things from outer space or a parallel universe so I'm probably not to be trusted when it comes to tings like this.

What I can think though is that my Lampi DAC is truly balanced and the Job's are not, and this combination causes the problem somehow... but I'm not sure. For now I'm just glad the noise went away, and particular happy that the static buzz went away. I'm really enjoying listening to music right now....

When it comes to cables I actually have no problem in trusting RCA cables and I don't see much value of using XLR's unless the components are truly balanced, double everything, dual mono configurations, and far from all gear that has XLR connections are built that way as I understand it...

In your mind you have abilities you know....
To transmit thought energy far across the land...
You close your eyes...you concentrate...
Together that's the way...
Upon the recitation we're about to sing...

I probably don't have near enough hours on my 250's yet, but damn... these little babies are soooo addictive! the sound is very organic, vivid, airy and 3-dimensional, it has punch with a very special touch or flavour or how to describe it. they are incredible fun to listen at and they keep dragging me into the music and especially if I turn up the volume a bit they're freaking awesome! I think they're a wonderful match with my DAC, preamp and speakers.... it might be difficult to tell exactly how much is thanks to what or how much of the others is shining through etc, but the combination of them all just feels absolutely wonderful to me. I can definitely relate to the feeling when Joe says they're here to stay, and I could not agree more, these will be with me for a long time. Also I want all of my gear now to be as tiny as they are.... hehe... :)

Told yah! Recall my month demo was with a Lampi B7 and an LDR Aum Acoustics premp (only Joe I know has one like it). I think Joe still has his...he can confirm. This means I heard them somewhat in a similar setup to you (but with Heil speakers). I was very impressed, but did not need the extra power vs the 225.

In the end I needed my modded integrated amp for its extreme versatility, but the monos were jummy.
 
haha, yeah... I think Job and Lampi should get married... they're like match made in heaven for each other.

I was almost for a while (like a nanosecond or so) considering exchanging my Lampi for a solid state DAC the other day when I found it to be a little bit too microphonic and causing some noise, but now I don't understand how I could have such dirty thoughts.... this is some seriously good stuff... :)

I am truly happy for you. These Job 250 monos, having the DNA of Goldmund, really shine compared to other amps anywhere near or several times the price. In my book, they are stellar. I love reading about happy outcomes regarding my recommendations. I know it can be tricky because we all have different tastes but I am confident in my Job gear. No brain-er for sure.

I do still have mine. Wonderful passive. Richard is dedicated to his craft.

Most of my speakers were fine with the Job 225 but the Job 250 monos and even the Job INTegrated show improved performance on my speakers.

These are my taste for sure, I'm VERY happy I decided to buy them. In 6 months time I've bought no less than 2 great products thanks to you and it seems one can simply not go wrong with a "recommended by joe" purchase... :) many thanks goes to you!

I'm carefully avoiding any new threads you are starting though.... seriously!!! I'm out!!!
 
:heart: :blush:


Thank you so much for the kind words. I can not tell you how much I appreciate it. I am honest about the gear that moves me. Glad you love it too.

Generally speaking, mosfets offer a sweeter sound. Whatever is in the Job 250 monos is wonderful and sounds great. I was listening last night with the Studio2 and was thinking to myself, what more do I need/want? Nothing! I love them. Absolutely great amps.
 
Yep, I usually don't worry too much about hardware design as someone much smarter than me (hopefully) decided what parts should go in there and what should not. I'm more of a software guy...

I'm still very very happy with my cute little Jobs, and I'm almost sad to say it but once I get my new upgraded preamp I don't really know what else to wish for... and maybe that is a good thing, allowing me to recover a bit financially as I bought way too many cables this year... it's very tempting to try some other speakers one day though, but that just has to wait.

Oh, I still have a pair of Synergistic Research Black fuses to put into the monos.... I have waited as I wanted to get to know them a bit first... I guess this is overriding the statement about trusting the hardware designer though... haha... :)

I have no idea... the 6moons review mentioned something about Exicon Mosfets though.

And for someone like me who don't have a clue about what a "mosfet" is, would it be a good or bad thing? :)

The metal–oxide–semiconductor field-effect transistor (MOSFET, MOS-FET, or MOS FET) is a type of field-effect transistor (FET). It has an insulated gate, whose voltage determines the conductivity of the device.

Dr. Oskar Heil, noted physisist and inventor of the Field Effect Transistor, began his research into loudspeaker design, not with abstract theory of how a loudspeaker should work, but with a study of the peculiarities of the human listening aparatus. The result of this intensive year-long research program led to his discovery of the principle on which the Oskar Air Velocity Transformer is based. By applying this principle to the design of a loudspeaker diaphragm, he was able to achieve a revolutionary breakthrough in solving the fundamental problems of diaphragm mass, inertia and self resonance. In the following, we describe the results of Dr. Heils research and how it led to the development of the Heil Air Motion Transformer speaker.
 
ahh, thanks... now I understand exactly what it is... or.. eh.... :)

as long as it sounds good they can call it whatever they want... hehe...
