You might be a tube guy if:
1) you know in your heart and soul that tube gear sounds better than solid state, but you stopped saying that on audio forums many years ago; and
2) both your amp and preamp use tubes; and
3) you have gear that uses nonstandard signal tubes (typical is 12AX7, 12AU7, 6922, 6SN7, etc); and
4) you would never consider using the stock tubes; and
5) you have a collection of tubes in storage, most of which you don't recall when you bought them or what component they were for, but you refuse to throw them away; and
6) you buy only high-sensitivity speakers.
