I hate to disagree but an old tube anything and I own 3 is not the way to start, so ditch the Mac idea. I do own a Consonance M100 plus nice EL34 output tube sound very conventional input, driver and output tubes which are easy to play around with, once you get the hang of "tube rolling" also it has a remote. List is $1600 but you can usually get a very good deal. Drives my 89db sesitive Von Scheickert VR2s with ease. Otherwise If Antique Sound Labs wasn't such a pain to deal with, I would consider them. If you are not sure if tubes are for you (they have special beautiful sound and imagry) Then don't invest a fortune in an expensive brand right of the bat. Tons of fairly decent inexpensive Chinese brands on the market. The Prologue is good looking but I have only seen it written about in the last year or so, my amp has been in production for about 10 years I believe. One word of caution you don't need a ton of "tube" watts- 30 and up is good,just don't expect killer loud music especially bass. Also don't start with a flea powered SET amp, if you had speakers that sensitive you wouldn't be asking this question. And I don't mean speakers like old klipsch which I have in my collection.
