Totem Dreamcatchers integrated amp, under $1000.

Haven't heard them together, but I've heard excellent things about matching Totem and Rega. If I were you, and depending on what you need in terms of inputs and features, I'd be thinking about the Brio-R and a very cheap DAC. I've had great results with a FiiO D3 (for $20-25). You can always upgrade the DAC later on ...

Creek is a good match too

Naim goes very with with Totem. I have heard the Naim Nait 5i-2 with Arro and Sffaf and really liked it. Should go with the DC also. Just checked, one on sale for just over $1K.

NAD could also be good. No experience with the Rega. IHMO, the Rotel can be a little forward and harsh, which may not mix as well with the DC.

could go with an older non-remote Brio model...this pop up now and then...creek, Nad, etc would also work...

You may be able to find a nice Arcam integrated amp within your budget. I've heard wonderful music with original Totem Model One's driven by an Arcam integrated. Have fun.
