JOB 225 2-channel Power Amplifier ... update ...

If your preamp has 2 sets of RCA outputs, you could vertically or horizontally bi-amp. I'm thinking about trying it myself but I don't really need the power. I'd try it for the fun of it.

But you're talking about using each amp as a stereo pair, with one amp on the bottom and one on the top, and not internally modifying the amp. I did this for years with Snell Type AII's and latter with Vandersteen 3A's.

Also after a week with the Wyred STP-SE I post some thoughts tomorrow in the other thread.

Thanks Jack. Yes or one amp per speaker. I guarantee if Job made mono amps from the 225, it would kill some of their more expensive amps. I think they want us to taste the good life of high end audio without breaking the bank. If they made monos, many manufacturers would go out of business.

I've never tried it vertically, only horizontal. I guess for wiring purposes, vertical may be simpler though.

It's certainly worth a shot. I hate to complicate things but sometimes it's worth a try.

That was the way the Snell dealer in Tampa recommended to do it, plus I was using two different amps with both set of speakers so that was the only way to do it. If you are going to use the JOB for both vertical would be easier. Might be worth a try to try it with the MR and the JOB if you got the MR biased. I don't know which one would sound better in which position, but if doing horizontal, then just swapping the cables at the amp end to try each way would be fairly easy. I guess at some point I can try the JOB on the bottom and my "little" MR on the top.
 
Jack,

The thing you have to worry about is the gain of each amp. The Job will get you very loud very quickly so you'd need some way to match the output of both amps. If you use two of the same amps, the gain is the same so no problems.
 
I had an electronic crossover back then, but my son has it in D.C. with the Snell's and yes I would have to pick up another one to try it. Probably not worth it especially since the JOB is about twice as sensitive as normal. Oh well, just thinking out loud. Let us know if using the two JOBs on the TAD's make any difference. One good thing about the Wyred is that it has two SE and one balanced outputs.
 
Now then, I prefer to put a separate stereo amp on each speaker to isolate the left and the right channel from each other. They will then for practical purposes function like two mono blocks.
As stated, the issue is regarding providing a mono signal to each stereo amp without losing anything due to inferior splitters.
If, as proposed, I were to have to two different kind of amps on each speaker, I would most likely use the type of attenuator that is in line with the actual interconnect, so far I have only seen this offered by one manufacturer in the past. A minimalist approach which is basically a volume control on the interconnect, possibly similar to the line control seen on some headphones. But if the Job is so great; Why mix it with another amp ? And if, what amp could actually enhance oe blend with it ?
 
Wow!

Very cool. I do believe the Job pre will be passive mainly because of the high gain of the Job 225. Just a guess. I can't wait to get one.
 
I really have no idea, but my guess is that the Job passive in the pic is an old unit and has nothing to do with what is going on with the new pre. I could be totally wrong, just guessing.
 
In regards to passive preamps and the lightspeed attenuator, I have used a dual volume control lightspeed attenuator for a couple of years. It is good, but the equally inexpensive Goldpoint passive preamp is better yet, and can also be configured for both balanced and se, dual volume controls and more. Also, One should not forget Atmasphere's preamp which due to its adjustability will take any sonic influence of interconnects out of the equation. Evenso, I believe Goldpoint will give you a 30 day trial period.
 
Have the Bel Canto 500M driving Pioneer/TAD S2/Ex 87db 6 Ohm speakers. Sideways move trying the Job?
 
Welcome to the forum 2glory!

Thank you for joining. My personal opinion is the Job 225 will be more articulate and natural sounding. Sideways? Possibly. But a flavor that I would prefer with the Job.
 
Gary, welcome.

Joe I think has driven the CR-1s with the Job in the past.

The Job is class A/B so may be more enjoyable than class D power to you.
 
My Job has been, probably, the most satisfying solid state amp I've had. I know it a strong statement but it's very musically satisfying. Sure other amps do some things better but on the whole the Job kills. Sound great on the TADs and Evos and Studio2's and .... There is nothing it sounds bad on to my ear. I don't play very loud so factor that in the equation.
