Job 250 monos amps: absolutely wonderful ...

I hope you are using Sweetcords with the 250s. They are a MUST. Thank me later.

Hehe... I know you want me to try the Sweetcords, and I'm very curious about them as well, my "problem" though is that my current powercords (Ansuz Diamond) are simply stunning, and I just can't see how they can be bettered by anything. I hope to be able to try them one day though, but I need to recap a bit financially first.

LoL

Its not about the cable quality in this case so much. The sweetcords have an AC curator circuit built into them and they are purpose designed for the job circuit which does not like power conditioners. THEY ARE MEANT to plug straight into the wall outlet via sweetcord. The AC power source is used like some kind of power reserve as well. Bad explanation for what is going on.
 
The sweetcords definitely sounds promising, and I promise I will try them one day... I don't know the technical details about my Ansuz products, but I believe their power distributor is very different and not really to be seen as a power conditioner that impacts on dynamics with filters etc. It's quite an incredible product actually, and so are their cables and I cannot speak warmly enough about them. They have changed my view on power, decouplers and cables forever.

I actually used the stock cables that came with the Job's for a short while when I was experiencing my weird XLR issues in the beginning, but then the soundstage kind of just collapsed and things sounded quite dull and uninspiring compared to when using my Ansuz cables. So while I certainly believe the Sweetcords is a great thing and a perfect match for the Job's, I have heard the difference with my cables also doing really really good things together with the Job's.
 
I've used the Sweetcord on the INTegrated, the preamp and Job 225 stereo (when each was hooked up). I bought them for the 250 monos but honestly have not installed them. I find the amps so good with my current cables, I have not even hooked up the Sweetcords. They are still in the bags. I'm too lazy to swap them in. I have 3 Sweetcords now and even like the one on my preamp.

Did anyone else try the Sweetcords btw? Joe?

Pretty please Joe,
Do the comparo and allow is to get rid of the nervosa!
You are uniquely qualified.
 
Joe, did you try changing the fuse in your monos? I just put some Synergistic Research Black into mine and first impression is that it's definitely worth it, I'll now let them burn in as I remember from doing it with the Nord's it took some time, but it sounded VERY promising right away.

Norman,

I just saw this. I'm using the sweetcords on my "regular" gear. I'll have to switch things up a little.

I have not yet. The damn things are so good as it is, I don't feel like messing with them. I should break down and order some.
 
Any idea if the job monos are fully balanced? Ayre gear seems to sound best through fully balanced connections. Intending to get this for my QX-5 Twenty before deciding on a preamp.
 
If I should elaborate a bit more on the topic, I've written before in this thread about my early experiences with the monos where I tried to use XLR connections, both directly from my true balanced tube based DAC, and from my passive transformer based preamp. The latter was not possible at all, it just gave a high static buzz. When connected directly to the DAC it worked, but I had lot's of noise in the speakers, which probably came from my DAC, but it was not acceptable. Today I'm running the Jobs unbalanced from my preamp with RCA cables, it's dead quiet, and sounds amazing... :)

I think this experience is probably not normal, but I also read in the 6moons review about the XLR connections being on the Jobs merely of convenience. All in all, I would say unbalanced RCA connections seems to work best in my experience... and hopefully it doesn't scare you away from the Jobs as I personally think there's so many other parameters affecting things that I would prioritize before going balanced again.
 
Srajan Ebaen did not mince words about the balanced connectors on the 250s in his review

we do know why the 250 can hum when connected XLR. With its single-ended input stage, its XLR is a mere convenience feature. It's not a true balanced input. What's more, it includes a protective resistor. When fed from a true balanced circuit like my new COS Engineering D1 DAC/pre, this resistor can cause hum whilst RCA is dead quiet. Faux balanced connections ...

+1

I’ve used both inputs and for me, both have been dead quiet. It usually depends on my choice of preamp.
 
I just put all my Ayre gear up for sale. I am very interested in the JOB Monos. I'm running Sonus Faber Il Cremonese and the VX-5 Twenty sounded good, but I know the speakers could use more power. Any good options for a preamp? I liked the KX-5 Twenty, but If I could get something that sounds as good for less I could treat my wife to a vacation for putting up with my audio addiction :)
 
As the Job mono's have an input sensitivity of only .75 volts the preamp will need to be low gain like your Ayre. Likely candidates would be to me Linear Tube Audio, Wyred 4 Sound STP-SE Stage 2, Backert Labs Rhumba or maybe even the Don Sachs Model 2 which has adjustable gain. When I was using the Job stereo amp I had to buy a used STP-SE to work with it as all of my tube preamps had way to much gain which is usually the norm rather than the exception. How much savings any of these will get you over the sale of your used Ayre is yet to be seen.

Wow that's a drastic move. Assuming you get the Job Monos and MicroZotl, what would your replacement DAC be for the QX-5 Twenty?

Good question. The Mytek Manhattan II is something I'm currently looking into.
 
The Ayre KX5-20 would be great but my choice would be the Micro ZOTL MZ2 with a sweet 12AU7 to lower the gain a bit. It's still only single ended but it's superb and will add some tone and 3D to the mix. The Job 250 monos are awesome, adding the MZ2 will be a great combination.

I'm not sure that you will gain much power, if any, over the Ayre combo.
