To Bi or not to Bi? That is the question


I have recently purchased a pair of Dahlquist CA2 and W2 speakers. These were/are a fabulous speaker designed to be bi-wired or bi-amped. For those not familiar, there are two cabinets, one for the highs (D'appollito array) and the other cabinet contains 2 6.5" woofers. The two cabinets stack one on top of the other and are bridged together. I currently am using the same amp I had to drive my old speakers which is a "modest" Hafler 9180 (105wpc). Needless to say, I'm not getting the best from my new speakers. What I am looking for help with is in the biamping process. I really like the 9180 which has that warm MOSFET sound and am thinking of keeping the amp to run the top cabinets. I would then like to get a stronger amp (looking at Hafler or Bryston)to drive the bass cabinets. I am a little concerned because I have read differing opinions on using two different powered amps in this configuration - some say they should be the same amp while others say a combo produces good results. What do you think? Also, my pre-amp only has only one set of outs for the mains, so a Y would be needed here - which brings me to another problem - where to fing a high quality Y (I am currently using AQ Opal to go to the main amp)? Thanks for the help in advance! BTW: I do not use an external crossover. Tony

Tmcroy somehow I've become a bass freak realy believing that subharmonic bass freequencies drow the main line of a sound signature and imaging. I also have the same monos as you do and probably will be planning to acquire 200W/ch-ish SS amp that is probably specifically great for bass(I believe it could be McCormack DNA1). The speakers that I have are Totem Forest(a great value for the bass freaks). I will also look towards building an active crossover with Marchand parts since I also believe that there is no point using different amps in passive bi-amping.
It is OK to use amps of a same kind without active external crossover.

If you can wait and stretch you budget(not realy big) or even browse to find used models of Rogue 88(power amp) and Rogue Tempest(integrated) that are designed for biamping together, you'll never regret. I might mistake on model numbers which means there are Rogue amps ntegrated and power amp having the same output power and double outputs for bi-amplification i.e. do the research.

And finally, I've enjoyed reading such controversal responces although choose to stay with my position that is completely in sink with Tmcroy.
