Default starving student vs jonokuchi or hybrid vs tubes for hd600 and sr80i ?

Currently i have xonar dx sound card as source, cmoy as headphone amp and grado sr80i as my first and denon dn hp500 as second headphones.

Now i am planing to make one more amp but this time with tubes.

My question is, is there diference in sound between hybrid and pure tube type of headphones amplifier.

I am also planing to upgrade headphones with sennheiser hd 600 and i thing that i should get bether amp than cmoy.

Now i am locking on those two diy tube amp.

Starving Student hybrid which is hybrid

and this one
Jonokuchi desktop amp which is pure tube type.

Which one is better for primarly sennheiser hd600 and secondly for grado sr80i which are just 32ohm headphnes??

Can't say much about the sound of either model. However, I feel you should also look into the practical issues before deciding on one:

- price: the Jonokuchi is going to be more expensive to build, because you need decent output transformers.
- high voltage: the SSMH can be built with an external 48V power pack, while you need to do mains wiring with a transformer on the Jonokuchi. Moreover, you have very high voltages (B+ is 340V) in the Jonokuchi. Only do that if you feel comfortable and qualified to do it safely.

I've built a Bottlehead Crack for a Senheiser HD 600 and the combo sounds wonderful. No output transformer needed. It was my first tube amp and I found it very easy to build. Have ordered their Speedball upgrade along with the amp but haven't upgraded yet.

...and I'll second the Bottlehead Crack - I'm using it with very old AKG K240 Monitor headphones (600 ohm) and the sound is very clean/clear. Easy build and excellent support.
