Of course it does. Tonight, Susvara sound particularly good from Ultimate with Philips E80CC and EL38. I am rather surprised that the amp seem to sound even better after one year. I just love this amp's performance so much. A tone that moves you and connects with you.

It's great. Hard to evaluate when all the drivers are good. :relaxed: I'm using Philips E80CC SQ with EL38 now. This thread seems to love the E80CC. https://www.whatsbestforum.com/threads/e80cc-comparison.34935/

Just heard from Matt. He's sending 12J5 tubes and 2 pairs of coupling caps to Eric for his Super Black Ultimate. Duelund CAST Pure Copper/Silver foil and Vcap Cutf. :relaxed:

Can't beat Bcowen. He has more GE and Fotons than me. :wink:

Tidied up. I'm getting a bit more organised. Easier to find my tubes now. :relaxed: There are some that are not shown here. Drivers and power tubes separated.

Using Mullard 6201 PQ with EL38 now. That's the tube on the right. Haven't tried this for a while and it's a pleasing sound. So many drivers and power tubes. Just change often. Says Made in Holland. The H has been rubbed off. Got a pair new from a friend.

Tube and solid state amps will never sound the same no matter how you mod the HD650. I've have a whole range of ss headphone amps before I gave them up for good and I did the whole shebang of modding HD650 following Purrin's method.

It should work because it's made to emulate the 807 and you have an adapter made for KT66.

For me the original HD650 with a good tube amp is sufficient.

@Deleeh your first picture of the EL38 with the double O or Halo getters at the bottom is exactly like mine. I'm just using it now with 6S3P. Eric is going to pass me 6S45P and adapters to try. The adapter goes on the 6S3P adapter. Whilst I like to try quad c3gs sometimes, I won't use it all...

I've done the complete modification before but I gave the headphone away. Now I just use it untouched.

It's a custom amp call Ultimate. This is where you can find out more info. https://www.head-fi.org/threads/mcchanson-amps-appreciation-thread.972577/#post-18090431 https://www.head-fi.org/threads/mcchanson-amps-tube-rolling-thread.972576/ Any other question you can message me privately because...

Yup still a good headphone even in 2024.

The ability to use 12.6v power tubes is a big plus. GU50 is a russian copy of the German LS50 and 12av5 is dirt cheap.

Yup pentodes and beam tetrodes. Far too many for me to enjoy now.
