Is the Cary SLP-05 still relavant?

I looked at Supratek before buying my SLP 05 and there were a number of issues that kept me from ordering one.  

Long lead time like 6 months plus was one, no balanced connections and limited number of inputs were other issues.  

Also the web site had virtually no information to help make a decision. 

Huh

Are you sure you’re looking at the right Cary Audio preamp? They have both balanced and unbalanced inputs and outputs. May want to double check. 

Seems to have passed the test, highly recommend one.

Anyone want to sell me their silver one? 😁

If any of you guys are still around, help me out here please. I'm a little confused on gain matching. The gain is high, 24db with balanced outputs, on the SLP-05. What is the ideal amplifier gain, or gain range for optimum performance match?
