I enjoy them, obviously the measurements of a no NFB single-ended triode amplifier aren't going to blow anyone away, but I find the sound delightful and tube gear is fun to design.
Here is a recording I made of my system using a Zoom H6 digital recorder, XY mic configuration recording 120 degree stereo. Obviously not the same as in real life, and further compressed by YouTube, but I think it gives a flavor of the sound. This is all analog, system below:
Turntable: Thorens TD 125 MKII (restored and rewired for 2x 3-pin XLR balanced output)
Cartridge: Hana EL MC
Phono: DIY balanced input MC phono featuring Lundahl LL9226XL MC input transformers, triode-strapped D3a / EF86 gain stages, all-in-one passive RIAA
Amplifier: DIY MH4 input / 6A5G output 3.75W single-ended triode featuring Lundahl LL1620 output transformers
Speakers: Snell J/II (restored, re-crossovered, drivers / tweeters replaced)
Maybe I should post this somewhere on a dedicated thread, just don't know if what I like to work on is of much interest to ASR readers.
The song is Moanin' by Art Blakey & the Jazz Messengers.
