Anyone using different tubes to stock ones/PsVane/Gold Lions that they feel is particularly amazing with HA-1 ?
I'll be avoiding the vintage ones though..too pricey some of them.
@WaveTheory are you using stock tubes ? While I see what you are saying about low Z cans and my Flux Lab FA-10 did have a tighter low-end it does not come across as flabby on the tube with PsVane on pre and amp section, more filled out is what I would say....I guess my set-up is at the borderline for what you were experiencing and I know its best to have a hybrid tube for planars to really control that low-end strictly.
Edit : Yes, am hearing that farty low bass with Sundaras which I have not tried on this amp extensively.
Guess I could use Ha-1 pre into a flux amp but pricey on that combo...the Flux lab amps kind of sound like a very transparent tube amp but they have a brickwall on volume increases due to their volume pot incline...you go form medium volume to super loud over the tiniest of dial after 1pm on the pot..is why I reverted to HA-1.
Also Audio-gd Master 19 cannot compete with the Ha-1 IMO, it lacks the dynamics Ha-1 has - strangely...that amp is loaded to the gills with components...but it all added up to just an 'OK' nothing stand-out kind of sound IMO.
I'm guessing the difference in sound on the HA-1 two 6.3" volume ports is a difference in voltage.
The left has a very dynamic mids focused/saturated SQ and the right port is more balanced on focus and less dynamic at matched volume...but it does get dynamic once cranked higher than left port...anyone else got an idea on how the two 6.3" ports sound different ?
