Nakamichi SR versus TA

My first SR4A started occasionally loosing a channel. So I installed the TA4A I had bought a couple of years ago as back-up.

Right now I am running an SR4A on my main system and the TA4A on my third floor system. I've had both the TA and an SR patched into the same system.

The TA does seem to have more bass though (agreeing with infinitebaffle) I think the SR has a more nuanced sound.

Anyone have an owners manual for a Nakamichi SR-4A? I was using it to run my Magnepan SMGc speakers but at 4ohm I decided to use a bigger amp. Bought a B&K 1400ii and connected to SR-4A via pre-outs but I get no volume control. Just full volume from B&K with no Nak control.

Another major difference between the SR and TA a lines is that the TA added "Pre-Out" and "Main-In" jacks on the back. They came with jumpers that can be removed and allow for introducing a signal processor or using these receivers for either their pre-amp or power amp sections. I can attest to the comments about the TA's that were made in China has inferior solder joints that fail over time and result in a channel dropping out or popping... that is what killed mine after some 25 years and for some reason shops do not seem to be able to trace the cause as I had it 'repaired' twice yet it still demonstrates the problem.

Did both have MC Phono stage? I believe Nakamichi made great phono stages. The one on my Receiver 2 is excellent. Recently someone advised me to compare the Stasis design to the HTA design.

Has anyone compared the Stasis amps to the Harmonic Time Alignments?
