I love my Cary 300/300 but not with the stock tube,
I have roll several set of tube RCA MULLARD and
other brands and so far the sound is just no there. It is very important that you use high end cable with this unit. I have use it with Cardas Golden reference RCA and Nordost XLR. It took a long time for my unit to finally break in. I have notice that it sound better with a Cary Pre Amp, I used to have a CARY SLP-98 that I called my little sweet things I upgrade to the Cary SLP-05 that I call the beauty and the beast. I think that the Cary brand is 2nd to none.
