- Greetings!
-
- I have an amplifier question I hope somebody here can answer. I
- was recently reading some literature from a company called
- TubeWorks, which builds musical instrument (read: guitar, bass,
- keyboard) amplifiers. They started out tube-only (thus the name).
- However, they now have a product line called MosValve, which uses
- MOSFETs, but wired up more like tubes than transistors, such
- that their natural tube-like properties come out. They claim (and
- apparently some reviewers agree), that this produces better tone,
- more volume/watt, and even-harmonic-only distortion.
-
- I was wondering if any of the audiophile companies have employed a
- similar approach to home audio amps to get a warmer, more tube-like
- tone out of their hardware, without the extra size, heat, expense,
- etc. of tubes. Since I'm considering putting a new amp system based
- around the Sony TA-E2000ESD, and will need power amps, I thought I
- might try to find something a little tube-like.
-
- Anybody?
-
- Thanks!

- PS: I'm sure that some of you will argue that tubes are just better,
- period. I'd probably agree with you on a tone-only basis, but there
- are obviously practicality issues, too. If this is a case of
- personal preference, please keep it short. If, however, you have
- some sort of technical shortcomings of MOSFET to bring up, yell
- away!
