Amp search


So I'm looking for an amp to bi-amp the upper section of my palladium p37f's. Either solid state class A or tube, between 50 and 100 watts. This is only going to do work above 550 hz with benign impedance loads. Budget is 2500$ so obviously used. The problem I'm having is finding one with 32 DB gain to match the the amp I will be using on the woofers. It's proving a bit tricky to find one. Variable gain one would be even better. Can anyone point me towards such a product? I'm open to  older models, within reason.

@atmasphere  I just learned from the manufacturer of my current amp that there's an input board available that lowers gain to 26db. This should make it easier to locate an appropriate amp. Are there any candidates out there that come to mind?

A crossover to match levels? Don't think I understand. As long as gain on both amps is the same, the levels will also be the same. There’s nothing wrong the my current amp btw.

 

Yes I know parasound offers this feature and I've heard this amp but that's way too much power and not really class A. Also not a high achiever when it comes to midrange and treble although it's ok.

I have a D Sonic m3a 1200s (class D) which I like a lot. It's just a a fancy I want to entertain and try something else but I didn't want to lose the bass and the control of what this amp provides so bi-amping seems like the way to go.

I wouldn't necessarily say I'm throwing parasound under the bus but i am familiar with that amp and not necessarily smitten. Also I am a firm believer in class D especially newer GanFet ones but they are few and far between and currently not many in the used market. Never owned a pure class A so that's why I'd like to see what' the fuss is about.

Not sure how I managed to miss that on Schiit website before but yeah, that might remedy the gain mismatch although I do plan on having the same gain on both amps. Like I said before I did manage to find a way to lower the gain on my current amp from 32db to 26db (currently awaiting gain input boards) so it should make finding a match easier.

Thanks but like I said I already own a good class D amp and am looking for class A or possibly a/b with high class A bias. Also it's seriously overpowered for my needs 

Yes active outboard crossover would technically be ideal but I really want to avoid going that route because it complicates things far too much. For example bypassimg my speakers complicated 3.5 way internal crossover and having the outboard active one sound as good? Tall order. Infact highly unlikely. Not a fan of DSP either unless it’s only in the low bass. I don’t really see a problem with feeding full range signal to a part of the loudspeaker even if low frequency are being blocked by the crossover and are turned into heat instead of drawing current from the amp to power the drivers, especially into high impedance load (above 10ohms) But there’s probably something I’m missing or are unaware of. With two gain matched amps there should be minimal differences that could be resolved with a passive analog line attenuator, like one mentioned above. No?
