Good morning.. I'm new to the world audiophile..thanks for adding me.. I've ran into a few good finds and I decided to put together something that's ok I'm guessing.. so I'll tell you what I have and hopefully you fine people can give me some suggestions. I recently bought a pair of paradigm reference studio 60s for $275 and two amps made by carver ..TFM-35 and TFM-15 With a preamp CT27v .. the 35 powered up with all working lamps,but no audio.im looking to send it to a place called hi tech in Gresham Oregon.. the tfm 15 is mint like it was just removed from box.. so I set the system up with the tfm 15 running the paradigm,Sounds great by the way. Now I'm at a loss how to add the tfm 35 when I get it back ..any advice how to add it in with the tfm 15 on the same speakers or should I just use the 35 to power another set of speakers? .. I was looking at a pair of cerwin vega At 15 or Ls 15 but I can't decide .please tell me what you think thank you
