I have been comparing my HD650s with my beloved HD495s and W5000s. Amps used were an AT-HA5000 (very handily has two outputs for easy comparison!) and a Kasuga KA-10SH (tubes). The HD650s do seem a bit weak, it has to be said. They...

Have you considered returning them for a refund? I know that audio being highly subjective it is hard to claim manufacturing defects, but this certainly sounds like it qualifies.

Thanks for the tips guys, sounds like a different amp is required. At the moment I have a HA5000 and Kasuga KA-10SH (tube) that I primarily use and they both work well with my 495s. It's so hard to buy 'phones like the HD800s because...

Yes it is output transformer coupled. I am going to give it some serious listening this evening and tomorrow now that it has as reasonable amount of burn-in on it. I had a listen to the demo one in the shop though and thought it was...

Here is the schematic and translation of the text accompanying it.     I will be going back to Kasuga next month and am thinking about getting another tube amp kit, and maybe the upgrade Alps volume pot for this one.

Evening all.   I finished the KA-10SH tube amp kit I bought from Kasuga in Tokyo earlier this year. It uses 6DJ8 tubes and is naturally 100V only so I use a step-down converter for 230V. The kit didn't take very long to...
