Integrated for 2500 new or used?

I don't believe any thing on the market matches this one
I have had Gryphon,MBL and others

UHF Magazine's Audiophile Boutique has recently discontinued Moon I-3.3 integrated amps on closeout. They come with or without a DAC or a phono stage, and there are refurbs at slightly lower prices.

you would not have to spend anywhere near $2500 on the used market to better the Rega ... many many options both solid state and tube

You might want to take a look/listen to the Wyred4Sound STI-500 or STI-1000(if you require more power). Very nice sounding integrated amps at a great price.
