Re: Premier 2 Blue Book Value

I've no problem fixing my self since I've built several tube and solid state amp in 80s and was a hi-fi technician while I was in college.

Premier 2 Blue Book Value

I got a Premier 2 needs fixing, one channel faded out after using it for 30 minutes. I have put in all new tubes and the problem still persist. Can some one tell me the blue book value such that I can make an informative decision regarding how much money I would spend on fixing it. Thanks.

Re: CJ Premier 10 Balance Control

When I fully turned the balance control to one side, there are still some sound came from the other channel and it was not totally mute. My other CJ Premier 2 pre-amp balance control can fully mute a channel and therefore I expect the Premier 10 will do the same thing. I wonder whether it is normal?

Re: Please Help Me To Choose Premier 12 or Premier 140

The search game is over. I bought a re-furnished Audio Research VS115 from ARC for $3300 shipped which is cheaper than both CJs which I am looking. It sounds great and it is brand new which came with ARC 3 years warranty. Now my system consisted of 1 CJ head amp, 1 ARC phone amp, 1 CJ line stage pre...

Re: Restored vs Modern Amps

I would say a $7000 amp made in 90-00 is always better than $3000 modern amp. In your case, I would prefer a used Premier 12 or Premier 140 over Classic 60SE. This is only my personal speculation since I have never heard those amps before.

Please Help Me To Choose Premier 12 or Premier 140

Please help me to chose between Premier 12 (140 Watt Mono Amp, made and end in early 90s) and Premier 140 (140 Watt Stereo Amp, Made and end in 00s). The 140 came with the inter-lave winding transformer but not sure about the 12. I think this will be my key tie breaker if the 12 did not come with th...

S.E.T. Vs CJ Amp

Lately, I am interested in Single Ended Triode (SET) power amplifier and have done some research about it. To my surprise that given their low output (3-18 Watt) and extremely high price (6,000-200,000 USD), people seems to like it a lot and rave about their sonic capability. My question is ... Any ...

Re: Hsu Research VTF-15H subwoofer with Rosenut Veneer Revie

My new basement media oom is about 18' W X 22' L X 9' H. I think it should be big enough to run this configuration. The only thing that I need to decide is to either spend the money on the sub-woofer or replace my 2+2 with KEF Refernence 201/2 full range monitor and then add the subwoofer later but ...

Do you think it is a good sub to use with my Accoustat 2+2 full range planner speaker? I mainly use it for 2 channels listening not setup for in-home theater. Thanks.
