Best Tube CDP for $2000 Budget

My Favorite CDP is the Audio Aero Prima - smooth, detailed, with the most realistice portrayal of instruments I have heard to this point. I left some more detailed comments here:
Audio Aero Prima 24/192 Mk II cd player......
My impression since then has not changed. The Prima is still difficult to beat at this pricepoint for a CDP (compared to the Linn Genki, Unison Unico CDP, and even my previous favorite the Planet). Also, I was never very impressed with the Cayin CDPs that I listened to.

Finally one more alternative: Have you considered a PC based system? Computer audio has come a long way and there are excellent dedicated USB DACs available. I currently use the Wavelength Brick and althought the sound is a bit different with the right tubes it does offer an improvement in most areas over the Prima.

Your best bet is to listen for yourself...

Ditto on the on the Audio Aero Prima a very smooth sounding yet detailed player. You can also buy the Audio Aero DAC. Another choice which is more revealing but superbly built in your price range is a bit more difficult to find. The Granite Audio CD 657. It is a tube variable output CD player which sounds great, if you can find one used it will likely be a steal, because most people are unfamiliar with it. Finally if you are thinking of an inexpensive player the Easter Electric Mini Max is very musical whether it has tubes or not. Given yor preferences the Rega is a perectly fine choice why switch?

I'll second the Prima and it can be had for a lot less than $2k. Also it's characteristics sound even better when isolated on a Silent Running Audio VR stand

Used Metronome should be on your list. Cheers,
