Does EAR324 phono stage sound like tubes ?

I had an EAR 324 for a a few months. It was initially quite impressive - very quiet, great detail, dynamic. But after a while I found it unsatisfying - to my ears, it had a cold, metallic sound which I found rather un-musical, so I sold it. I also borrowed an 88PB which I found to have a similar tonal quality, although with a little more bloom. Again, though, I found it too cold sounding for my tastes. I have gone back to using my Exposure 13 phono stage (which has not been manufactured for about a decade), although it was much cheaper and perhaps less quiet, and certainly less flexible than the 324. It is, however, far more musical.
