BTW the link above is only one of many that they custom make.
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.

Thanks @onhwy61 , I just found this https://apps.apple.com/us/app/boom-bass-booster-equalizer/id1065511007 I'm out of town, so I can't test this at the moment. Looks promising since Tidal is my only source! |
You are certainly on the right track. By using separate amps with separate volume controls, you can increase of decrease the bass without destroying the linearity of phase aligned speakers, and without changing the linearity of the bass output with a tone control. I am a definitely a Nelson Pass fan, and had forgotten about his pre-amps with dual volume controls, so I use a pair of Audire Diffet 3's. It really works! From my comments, you would be right to surmise that I would never go with an EQ. |
Guys, what about a pre amp with a built-in EQ, like this McIntosh MA9000 https://www.mcintoshlabs.com/products/preamplifiers/C53 |
@onhwy61 You mentioned tape loop. Like this "tape output" https://www.ayre.com/wp-content/uploads/2018/05/KX-R_BACK_Web.jpg And how/where do I add the equalizer in that scenario? |
