Will this amp trick work for increasing bass performance?


I'm considering matching Focal Utopia Scala Evo with two amps for bi-amping, to separate bass and mid/high. 

I'm considering the Pass Labs XP-32 pre-amp, which has individual volume controls for each channel/amp. By slightly increasing bass amp volume over mid/high amp volume, I get to feel more punch from the 11" woofers. The crossover in the Focals cuts off at 220Hz, so only bass and sub bass are affected.

Which two power amps would you consider? Power amp budget is about $30K. Was told Focals like power, so >250W for bass amp seems the minimum. Pre amp will likely be Pass Labs XP-32.
Maybe Pass Labs X250.8 + X150.8 or X250.8 + XA60.8?

Your thoughts please? Any other ideas to get more bass performance from the 11" woofers in the Focals? Subwoofer is not an option. I know McIntosh has a pre-amp with equalizer, which would solve the problem too. But I always thought EQs are a no-no.

30K for bass? Even millercarbon is being is being overly nice.
Good lord...XA60.8 for bass duty... I would never..
That’s a sin not an insult, God can forgive ya, I can’t... LOL
Crown or Parasound maybe, most likely a great class d for 1000.00 or so a pop..
500-2000 watts of pure dark background, cool running amps, that idle at 25 watts..
11" boom, booms will have plenty of headroom, room....AY..

30K Wow.. I’m truly envious. I really am, rare for me. Enjoy...

Tell him MC, spread the word...I’m a column and OB servo guy myself...

DBA is kinda like a Gatling gun, bound to hit something. sooner or later.

BUT it’s better than most...

BTW, saw my first and only UFO in 1976 on July 4. Over 100,000 people saw it in the Bay Area. It was never explained... A true UFO.

Weird... Bicentennial. 5 lights. There is actual footage, GOOD footage..

What a night...Pioneer 6x9s x 4 with a Crag Power play 8 track.
James Brown....Tighten Up....

Regards,
The product is wonderful, just a dream come true..

Either or, both are just a Wonderful, a wonderful.. !!!

But bass duty...Really. I suppose it has to look good I suppose it need to match? I duno..

I shouldn’t say things like that.. If you’re looking for the best, you chose it for sure...

I’m still thinking, if I could, would I? Answer is still no..

I couldn’t.. BUT, I’m pretty frugal, 5 or 6 depressions ago maybe.. LOL.

Enjoy whatever it is.. I say great class Ds, will make um hum.

Pass, oh yea..they will sound great... I guess I’m a little grumpy, finishing up my projects..LOL

Ok we're up to 35-38k, for a little more bass, and control.

A Pro mixer in a stereo system? Is that what you're suggesting?

Why?

Everyone keeps saying DBA, He states NO SUBS.

I bet this is a VERY nice room. 

I would use something quietly hidden, with lots of goodies for bass management...300.00 USD tops, daisy chainable, laptop for TOTAL access, parametric and graphic EQ,  threshold limit, timing correction, phase correction, L/R channel summation or MIC data collection/measurments, for real time on the fly remote correction.

Choose good amps. I like class ds doing bass, just makes good $$ sense.. Plug in, have fun...

I've used OXO for bass management 20+ years..
Nothing gets close with my frugal budget..

It's not the Gatling gun, DBA approach.  Much less floor space is being used, or covered in boxes... OPs decor, may not tolerate DBA, not to mention, partners, and or guest..

You don't even have them in your room yet, so you don't even know how they will perform.

I think he has, that's the reason for the biamp, unless I missed something.

He has the speakers, but only a single amp per channel, he want two for more boom boom, in the room room... BUT he wants no subs...

30k budget... 3k aught to do it. He may be picky,and likes Pass, nothing wrong with that.
