Older Nakamichi Gear ?? Stasis ??

My opinion is that OMS-7, or 7II & SR-4a or TA-4a & you will have very wharm sound ...

Having owned a lot of it and sold it when it was new. The TA and SR amps are quite nice. The CD Players are pretty bad sounding by today's standards those.

I had a TA-3A which worked wonderful with a pair of Kefs. Not a bad sounding amp for pennies these days..

I would stay away from the older CD players though..

I've owned several Nak pieces over the years. Used to sell it back in the late 80's. I currently own a Nak Ca-5 preamp; MB-2s cd player and SR-3A reciever. I also have a broken OMS-5 cd player in the closet. Stay away from the RE series receivers as they are not anywhere near the quality of the SR or TA series, nor they sound anywhere as sweet. The SR series was the best receiver they built. Lot's of current well designed and practially bullit proof. Very open and dynamic once the idle current stabilizes. These have high idle currents so they tend to run on the warm side and need to be on for awhile to sound their best, IMO. The TA series stopped being buit in Japan and I feel it had a slightly lower build quality. Also they added video switching on all models and seperate listen/record tape switching which makes the design a bit more complicated. Same basic Stasis design as the SR each model produced more watts than any of the SR's. The TA's are still nice sounding units and it might be hard to hear a difference. The build quality and the additional switching are the weak links IMO for the TA series

The biggest problem with the OMS series of cd players is their age. If the transport mech. or laser assembly hasn't ever been replaced, I'd be suprised! This is a major expense if you can find the parts, and frankly the player isn't worth the repair. These players use old conversion technology, which at the time was the best, but now is mediocre. I'd opt for the original MB series if you're looking for a changer or the CDP series if looking for single. The MB(S) series has been known to have more transport problems(lesser build quality) than the original MB series, but I've had mine 7 years w/o incedent (knock on wood). Again almost impossible to get parts and more expense than the player is worth. They sound OK, clear and detailed, but completely lacking in soundstage width and depth. I use mine with an outboard DAC. When my MB-2S bites the dust I'll get something else rather than fix it.

Hope this helps.

The SR-3a seems to be the high point of the stasis receivers.  I have owned some of the SR and TA series, the top two, and never liked the variable loudness.
