Biamplification in Mid-Fi?


I'm looking at upgrading my home system. It's likely going to end up being mid-fi. (Paradigm Reference Studio or B&W CDM Speakers) and I'd like to bi-amplify.

Ideally, what I'd like to do is use a quality integrated amp (Audio Refinement, Audiolab, Arcam, etc.) with a second (matched, but more powerful) power amp for the lower frequencies, and also be able to use the system as the front end of a Home-Theater system.

What I'm wondering is whether or not I'm better off to use an active crossover (brands, anyone?) and bypass the speaker crossovers altogether (which would require some rewiring, but I'm going to do anyway, to upgrade the internal speaker wiring), or save on the signal path, and just split the pre-out to the two amps?

Any opinions?

The issue of being complicated is half the fun (I like to play with these things). As for a major step, I'm going to be upgrading from some old NAD stuff & NHT 1.3's over the next two years on a rather limited budget. I don't want a too unbalanced system, and I don't want to sink too much into a CD player before letting the new formats work themselves out...

I feel the most important step is a new amplifier, likely an integrated, and I can retire my old NAD 3020. But the truth is, I see an upper limit to this thing around $5k for everything (Not including Home Theater).

Sounds like keeping it simple is best...thanks everyone.

But, the idea of building a set of speakers is interesting. Problems is, I worked in Pro Audio (sound reinforcement) and bi & tri-amplification is pretty standard. For awhile I had my old Paradigm 7se's biamped with NAD stuff, simply running the larger power amp to the bass set of inputs and my 3020 to the highs (using the internal crossover in the 7se to split the signal). I used a pink-noise generator and a Real-Time Analyzer(RTA) to set the balance for the room, and found improvements in detail, and tighter bass (was still kinda boomy, though). Since then, I've been thinking of trying the same thing with (somewhat) better equipment.

Oddly, its always been my opinion that with all the R&D manufactures put into their designs, that I could never approach anything they could build, yet I have a friend who builds excellent speakers/subs for pro sound reinforcement. I have the background in electronics, but not in acoustics, but I think it would be worth talking to him about it. The expense would be minimal, and the fun maximal, so why not?! I may suprise myself....

In the meantime, I think I'll be saving my $$$ for that cheapo YBA integrated (The Audio Refinement Complete), and biwire using some good cable (better than my current Moster Cable)

P.S. Thanks for the suggestion on the Richter Scale...looks like a lot of fun!
