Info on the Cary slp90L?

I was searching for some info or reviews on the slp90. I should be recieving this unit on Thurs and although it has some age I still should be able to find something on it. Also if anyone has this unit would you share any tweaks or advise. Thanks in advance
I used to own one of these pre-amps. It's very nice sounding, sweet and full. Try some NOS tubes.
I also use an SLP-90L. In the past ten years, only it and my speakers have remained constant. I've never seen any reviews on Cary preamps.
I owned the Cary and it is midfi at most. Their amps are Cary's strength
