OK ghd. At 90 years old soon I have no right to make mistakes for what will be my last improvement. So which preamplifier could replace my CJ? ARC, CJ, Manley, Cary, Cayin, new or rather used.

 I’d start by upgrading the DAC before anything else. My suggestion would be a DAC from Lampizator, LTA, or the AQUA (like La Scala Mk II).  Any of these would represent a substantial step up from the Mytek both in musicality and overall refinement.

There are many used DAC listings here and on USAM.

Maybe and CJ ET7SE? This is a contemporary CJ Preamp. Changing brands would add an additional level of complexity. I think the CJ is a very complimentary preamp in your system.

Lampizator, LTA, Aqua ,are not available over here in France. 

CJ ET7SE used not found . What about a used Cary SLP98P ? or aARC LS27 ?

I have an all Audio Research system. If I didn’t It would be all CJ. Yes I would highly recommend the LS28SE, or LS28, or LS27SE... how ever far back you have to go back. I have the Reference series.

A good friend whom I helped to choose his system has an LS28SE. It will a bit more detailed and neutral, but musical like your CJ. If that appeals to you.

I feel that the warmth of your CJ helps to offset the more neutral lean Manhattan.

I’d put your equipment and proposed changes into ChatGPT and evaluate to sonic characteristics of the change. It typically does a great job.
