Summary:
Considering I inherited it (free)from my father who switched to remote controlled mckintoshes, the P-4 is superior value for money. I did compare it with his new amps some time ago and it sounded similiarly silky. After 1 hours warm up, the CJ is seductive and you tend to forget its lack of bloom and sustain, and will get into the music. Replacing the tubes, will probably give it a new lease of life although the whole set of tubes will cost S$800. (anyone tried Sovteks, gold lion and other brands?) Currently makes great sound from a Philips CD 842, Motif (CJ kit) FET Pre and vintage Polks via unknown brand interconnects and 'installation' grade Nordost wires. Next upgrades will probably to Maggies 1.6QR (to increase height of soundtage) and the CD player (for more detail) - should it be ARCAM 72, Planet2000 or a really practical 300 disc changer and a good DAC? Still searching for that elusive vinyl analog sound. Suggestions welcome!

depth of soundstage,full-fatty bass and outstanding mid range

missing the fine delicate treble

Summary:
I bought one of these used in near mint condition. I find the sound to bequite nice on this amplifier. The construction is quite robust, and this
amplifier weighs in at a substantial 82 pounds. I have no complaints with the
purchase of this high end quality amplifier. The use, and set up is quite
easy. To bias the amplifier all you need is a small screw driver. You simply
turn the screws for each tube just until the red led's go out. That's it. This
amplifier uses (8) EL-34 output tubes. I expect this to last many more years,
and continue to sound as expected from all Conrad Johnson products. This amp
puts out a hefty 100 wpc and should be able to drive most any set of speaker. I will give this unit and enthusiastic 3 star rating out of 5 stars. Just remember to get some lifting help when you lift it out of the box..

Summary:
One of the biggest disappointments ever. I purchased the Premier 4 new when it was first introduced. I was lucky to unload the thing. About the only good thing I can say about it was that it looked really good.
The sound was nothing like the Premier 5's or the older MV75a1's. In fact, the MV75 is a much, much better amp at a lot less price.

A poor product from a great company.

Summary:
This preamp is smooth, warm and three-dimensional, particularly in the mid-range. It is very life-like when played up to moderate listening levels. Also, it appears to have a very robust build quality; 80 plus pounds for a 100 wpc stereo tube amp. I chose this amp after owning PS Audio, Threshold, and Quicksilver. I don't think I'll ever look back!
