The Little Dot Mk V drives my Sennheiser HD650s nicely

Listening by the early morning glow of tubes!
A little dusty these days! Decware Taboo III.
I have the same and like it a lot. Goes well with my high-impedence Senn HD 650's. Curious what tubes did you upgrade to? I upgraded mine to some GE 5654W
drivers and Novosibirsk 6H6P power tubes. I think it improved the sound but nothing night and day. I actually thought it sounded quite good with the standard tubes but just wanted to play around with some tube rolling as much as anything. Great product for the price!
I got mine for $129 from Amazon. It was too good a deal to pass up. The price has since been raised.
So far I've replaced the input/driver tubes with GE 5654's from Riverstone Audio. The outputs are stock. Do you hear a big difference between the stock output tubes and the Novosibirsk tubes?
My only caveat is that it tends to run somewhat hot.
The Audio-GD R2R 11 (headphone amp/ladder DAC) in it's final resting place at home...
At the "testing facility"...the office:
I think 'hot" is normal for a Class A tube amp. Mine gets pretty warm as well but nothing outrageous. I certainly don't think the Novosibirsk tubes made a huge difference and they weren't cheap at around $45 for a matched pair. Admittedly I haven't swapped the stock output tubes back in for any real A/B comparisons. As I'm sure you found rolling the driver tubes is pretty cheap and I'm fairly sure the better bang-for-the buck.
Okay it finally came in..

Replaced my PRE-AMP in my main system..
WOW , I really like it..
That is a really nice amp.
Bottlehead Crack with speedball. My main amp, used with either the Beyer DT880 600OHM or Sennheiser HD600 headphones.
I had a CSP3 for a while driving a pair of DT880-600 phones. It was a very good match up! You need to roll some tubes to find audio nirvana!
