i dig my musical paradise mp-301 amp. these days its dedicated to headphone duty. love the tube rolling capabilities of the amp. the sound of the amp is good - but could be better.

does anyone have mods or upgrades to suggest?

thanks for any input.

regards -andre

It seems you've found your sound. You could do a few small things like rubber rings around the tubes. A power conditioner of some kind.
Tube rolling is easy. You like what you have. Don't end up with a load of money invested in a drawer full of tubes. Still, I'm glad I have my stash of 6sn7, 12AU7, etc. bought thirty years ago.
Of those tube options I go to RCA 6L6 first. To me the first consideration in tubes is quiet. Eventually I had only two venders I bought from on Ebay. Once they knew I was a repeat buyer who exercised "buy it now", they provided guarantee. They even looked for what I wanted. And I paid a fair price for their knowledge and expertise.
If you solder then caps can be changed. Other than that, I say listen to music. Can you listen to IEM from this Amp, or is there hiss?
