Thank you everyone for suggestions,
I'd like to keep this preamp at least for a while for several reasons.
One is that there is more in its sound that I like than what I dislike. The soundstage is great and instrument separation is just incredible, IMHO due to dual mono design.
Another reason is that CA-7A is a "control" preamp, allowing to remotely operate another Nakamichi gear connected to it. I found this feature very convenient to control my Nak Dragon.
Finally, what I hear now is a sound of a "stock" CA-7A version which I believe could be improved with modification of circuits or just simple things such another (dedicated) power cord or an interconnector cable. It worked well in the past and so I hope it will also work well this time.
I will try some Cardas cables, starting with Crosslink, and also Audio Metallurgy GA-0, Audioquest Diamondback and perhaps some others.
Stay tuned!
