NAD C 375BEE Integrated Amp Replacement Recommendations

Outlaw Audio has an integrated? I know they have a receiver. And, more refined with more grunt than a NAD C 375BEE?

There's a used NAD M3 listing atm. Heard this at a couple shows and sounds smooth and powerful. It's an older item, though. They just released a streaming M10, which might be worth a try and new, it's within your budget.

I am not sure you will find anything that would make for a significant improvement over your NAD at your budget. If I were looking for an $2500 integrated, I would look at the Vincent SV337Mk. Sold by Audio Advisor.  

motokokousanagi, thanks, I used to own the NAD M3 many years ago with different speakers. Had the M2 as well. Not sure I would go down that road again.

mr_m thanks, I was thinking about the Rogue Sphinx II after reading post about it in another forum. What’s your experience with the Sphinx if I may ask?

Any old schoolers here have thoughts on the Jeff Rowland Concentra- does it have enough low end weight/? I'm certain it should be refined and resolving.
