If you are happy with Rega's tonal profile, I would look at the following.
Rega Elicit R - you get more power and a better transformer as you step up. Rega integrateds do improve as you rise in the line. I believe this lists for $3K.
The Naim Nait XS 3 is going to be $3490 and is a VERY nice integrated amp. Naim tends not to have high power output into 8 ohms but will be shockingly good with tougher loads / lower impedances.
The Rogue Pharaoh is a hybrid. It has a tube input stage and a Class D Hypex output stage. It uses two, relatively inexpensive, tubes in the input stage that soften the edge you sometimes get with some Class D amps. I own the Rogue Hydra which is a power amp that has been around for a while. I love it but you would need to roll in different tubes.
These are three options that tonally will keep you in a similar place but improve the quality of your amplification. There are many others that I have no doubt will also work.
I am a dealer for Naim. I have no affiliation with Rega or Rogue other than I am still an owner of a Hydra and former owner of a Brio R.
