My evaluation was totally different. The Ref 2 MKI was boomy in the mid bass, very noisy and tonally off. Although it is still quite good, the MKII using the 6h30 tubes is much better. It is a bit quieter, faster and more tonally accurate.
I would recommend you listen to the Aesthetix Callisto MK II as it is in a totally different league. The other preamp that is very good is the BAT VK-50SE.
If you have any questions, email me directly.
Good Luck!
