The 5998 is hard to beat for sure.
I still want to try a GEC 6AS7 but I'm definitely waiting for a deal. The prices they are going for are ridiculous.

Theyre not cheap, but worth it. Very different than the 5998.

I was taking a short sabbatical a few years ago from headphones and this guy offered to sell me a pair of GEC 6SA7's for a very reasonable price. I already had a pair, so I turned him down. I regret that decision constantly.

Waiting for some ZMF headphones to listen with my tube amps. :relaxed:

So, of all those beautiful amps, which one(s) did you like the best w/ ZMFs, and why?

They are some beautiful sounding amps with ZMF headphones but the amp's that is most special to me is Odyssey. It will sound gorgeous with ZMF headphones no doubt. This is an old school amp using amazing sounding Sowter output transformers. It's rich in tube tone but also tuned for extended treble sweetness, fast transients, engaging midrange and mid bass with impact. With Susvara, I've indulged too many hours listening to music.

I am sure it will drive Caldera very well. Likewise all the ZMF dynamic headphones.

So are you a rectifier believer yet? If I recall correctly your GOTL was a HEXFRED design.

1 - Great thread! Thanks for starting it...

2 - No love for SS here?

I have a couple tube amps (Woo WA3/OTL; Icon Audio HP8/TC) and of course my VO and Aeolus do well on them both. But my long-time reference for all my headphones is the Violectric V281, still my favorite overall amp. It's also a superb preamp--I use it as the preamp and #1 HP amp in my main desktop system:

I also get a lot of mileage out of the LGX on my planars (my beloved ZMF Ori & Final D8000). And the inexpensive but very nice sounding Cavalli Liquid Carbon v2 sounds great on just about every headphone.

If the Caldera ever finds its way here, it will get serious time on the V281 & LGX, both of which really light up planar headphones.
