system synergy

So, the basic question is: how important is synergy between amps and preamps? In particular, how much benefit can be expected from mating amps with preamps that are in the same series? One would think that a good signal from a preamp is a good signal from a preamp, but I imagine impedance and maybe bandwidth matching might be very important. I'm not gear-head enough to say.

There is likely no general answer to this, but I do have a specific case in mind.

I have an Accuphase P-300 and an CJ Motif CR8 Pre (solid state). Both of course excellent vintage (and vintage-ish) units. But the Accuphase was designed with the C-200 preamp in mind, as it were, and the CJ Motif with the CJ Motif power amps in mind.

So, what would I likely find if I switched the Motif for a (sound) C-200 (features aside)? And likewise, what woud I find if I switched the P-300 out for a Motif Power amp (assuming proper matching with loudspeakers)?

Any experienced answers, or even educated speculations appreciated.

Thanks.

One obvious note is the output impedance of the pre to input impedance of the amp. Try to stay at least 10X the latter of the former.

that said I think you can assume that one company would make their own gear sound good together.

You should be good from an impedance standpoint. It's a general rule.

I don't think that system synergy is dependent at all on same-name components, it just makes the job "easier" if you elect to go all one brand. Of course, that's not half as fun as trial and error :)

Again, a long way of saying trial and error. If you have a piece of equipment you want to try to stick with, then you start with that and build from there. If you get the same brand associated components it would take away the trial and error part, not necessarily if you will like the house sound.

Right now I'm toying with this stay-or-go concept with respect to my speakers -- whether to ditch them in favor of some tube-friendly more efficient ones. Cost and the unknown (ie after spending a lot of energy and money will the new system blow my mind or not....) so I've elected for now to keep the speaks (ie the 'safe' route). Therefore the amp requirements are set. But I want a tubed pre so trial and error with that. Not sure there will ever be the ultimate set up, as one agon member said "if you find something you like, appreciate it."
