I bought my 1050 just about a year ago and I love it, so does everyone that hears it I recently got a new pair of mains, JM Labs Cobalt 816's, and would like to bi-amp them just for fun. And I happen to have two old Adcom GFA-2 power amps Problem is the 1050 only has one pre out for the mains. Any suggestions on how I might over come this problem?

Thanks for any help

You can try a pair of THESE .

Do you want to bi-wire or do you want to bi-amp? Two completely different things!and if you want to bi-wire, I would recomend to use the amp on the Outlaw for your tweeters it will sound better then the Adcom,and you could use the other Adcom for your mid-low in woofers.

I want to bi-amp, one amp for the lower end another for the higher end. Euro, you recomend using the 1050 for the high end? As I understood it, you should use the same amplifier power for bi-amping. Is this not true ? or at least not critical?

Well if you want to go Bi-Amp you are going to need an electronic cross over,(a 2 way)according to the manual of your speakers.Then you would use one amp for the lows, and the second amp for the highs,unfortunately you could not use the amps for the mains from your 1050 if you decide to go this route.But what is the main reason you would want to go bi-amping!Would it be that you are looking for better dynamics,more clarity and less compression?Or could it be you want to play them at rock & roll levels?

LOL, I'm getting too old to listen to music at high volume for too long now. Although I do appriciate a bit of Queen's of the Stone Age or Metallica once in awhile.

You do not necessarily need an external crossover to bi-amp. You can just use the internal crossovers. This would be a passive bi-amping configuration. Your speakers may or may not be capable of this type of biamping. Please check the documentation that came with your speakers.

The external crossover would be active biamping and is more efficient since you only send the appropriate frequencies from the x-over to your amps. This will work well if you can bypass the internal crossovers on your speakers.

Biwiring uses a single amplifier for each channel and runs a seperate speaker wire to the tweeter and midrange/bass drivers. Therefore you only use two channels of amplification for biwiring whereas you use four channels (or more) for both passive and active biamping.

For either biamping mode you would need to split the preout from the 1050 using some kind of splitter such as the one in the link in my post above.
