Don't try to influence Greg on what headphone he should have. Everyone have their own preference. When I say that I have been through as many headphones as tube amps, I wasn't kidding. Audeze LCD2f, LCD3f, LCD-X, LCD4, Sennheiser HD650, HD800, Beyer DT880 250 ohms, T1v1 and v2, ZMF Eikon...

HD800. I don't mind HD800s but I prefer HD800. I bought the HD800s for my son so that I can keep the HD800 for myself. I was just at his place on the weekend listening to the HD800s with Violectric v281. The v281 is a nice sounding solid state with slight warmth but Ultimate is much much...

The only change I made to my HD800 is to replace the pads with ZMF pads for HD800. I have not remove them since and that's almost a year ago. I go through as many headphones as I do tube amps so it's a surprise that I am really enjoying HD800 now with Ultimate. It's a marriage made in heaven...

In case you're wondering why @rollinbr hasn't post in a while, he has just moved and have some health issues. However he is enjoying his Super Silver Supreme with WE300b tubes. That's what he told me. @Leicachamp recommended a friend to McChanson amps and he ordered Destiny and a Junior Wooden...

No he has quit. This job is too hard. It's constantly changing. You don't need a spreadsheet. Everyone should be an expert now. Every tube and adapter should be at fingertips. :wink:

I know of someone who has some of the best tube amps (Eddie Current 445 is one of them) and he has only one headphone - HD800. Congrats on the 5b/254m and the adapters while they are still available.

See I'm typing it wrongly myself. 5b/254a. These alpha and number names drives me nuts.

Those are 5a/254a. Both 254m and 254a are excellent in Ultimate. Deya's adapters for 5a/254m might be coming tomorrow.

Only buy tubes that matters. Quality over quantity.

Why give up buying tubes? It's a hobby.

I will get my 5a/152m adapters on the 21st of June.

GE 6BX7 and proud of it. :relaxed: GE 5U4G

We blame @bcowen for giving GE a bad name.

Skull goes back a long way. He's got the best ears.

This statement is 100% correct. I have never had a tube amp that is so adaptable. Not GOTL or any of the tube amps before it. Ultimate is the ultimate. Not only is it adaptable but the tubes sound their best in Ultimate. Even Odyssey is not that adaptable. I had a listen with GEC 807 ATS25 in...
