The reason I was asking about the Rotel is that I have the Pre-5 too. I love it. Stepped down from tube pre and this little Pre-5 is spectacular. Not as airy as tubes, but it does so many things right and has a beautiful sound. It is a gem.
I am currently using it to drive a Pass Labs Aleph 30 amp. It matches well but I want more guts. That is my interest in the Rotel. I haven't heard there newer stuff and was interested if there is synergy between the two. It was either that or an Audio Refinement Multi-2, 3, or 5 power amp. They are 125w/ch. Is that enough for Maggies as I have thought about them often, but not with my current 30/ch. I want more flexibility with more power than my 30/ch class "A" amp.
If you listen to CD's a lot a dedicated cdp will really bring your system to another level. I discovered the Cary CD-308 last year and it is spectacular. It can be gotten for about $850 used. Not much can compete ar its price. Great detail, bass, soundstage, clarity, and w/o grain.
What amplification do you use for your HT speakers? Do you use another set of outputs from your Pre-5 to another amp for HT? It sound like a good idea that I may try.
Anyway, you do have a system to be proud of.
