Improvement?

check out the jolida and prima luna separates or integrated tube amps. these would be a more musical setup than the NAD/Creek combo. i used to own a pair of arros, fantastic little speaker. easy to drive. i used a small jolida integrated in my den with excellent results.

howabout adding more Rega gear?

If you don't have room treatment and want an improvement this is the ticket. Room acoustics have a huge effect on the sound quality.

Consider that the average room has peaks and dips of 15db! This is like letting a child adjust a graphic equalizer for you at random. That's what the room does to your sound.

You'll hear more of an improvement with room treatment than changing amps could ever do if you have an average room. What's an average room? Good question. Please go to the acoustics circle at audiocircle or Ethan Winers site realtraps.com and read. Also of course do a search here and read. This could be very interesting to you.

I apologize for not suggesting an amp. The reason I suggest trying to improve your acoustics is because alot of us who've been in the hobby didn't realize how important it was for decades. It's hard to imagine the improvement until you've heard it yourself and I get the impression you're newer to the hobby than many of us here.

Btw you came to the right place for help. There's thousands of years of experience on these forums.

I suggest pairing the Arro's with warmer sounding electronics. I agree with Rbstenho about Jolida. I use the Jolida 302b integrated with the Arro's with great results; this is a very good pairing.

You won't look back.

Try a used sim audio I-5 integrated...good match with totem for me. Upper end integrateds can be better than lower level seperates. Portal Panache Integrated is a good deal new or used.
