Open Up Your HD650/6XX cans with this Tube!
by Tony Fernandez
These sound phenomenal, mind you my ears are use to solid state amps, just got the Darkvoice, and have jumped in to this tube rolling thing recently. The Tung-Sol I grabbed from here sound great too...but these, the Electronic-HArmonix...wow, so open and spacious, and clear, everything feels tighter, faster, so good this tube.
Worth every cent I paid, overall tone is very very pleasing
by Barney Wee -
Worth every cent I paid for. Before I forget the low shipping price (before the covid19) was a clear incentive for me to buy. OK, the quad of this tube, is on the overall well integrated. The bass noticeably palpable (not bruce lee punchy), and the highs are expressively controlled (can be a little more extended). But the overall tone is very very pleasing, nothing jumps out disproportionately. BTW, I used it on my Schiit Freya+ Preamp.
