Yup grail is good:Alex
Oh gosh..... with high impedance cans like mine and Senn 650's its as good as it gets.Its scary real... just absolutely all around wonderful performance.Totally dead silent, soundstage is surreal.Bass drum, kick drums are so so tight, taunt...There are other good amps but this crack from bottlehead is one of the best.I don't want to get all mushy on this one, but a real lover of listening to music will be in audio heaven here.It always sounds good to me, just as good as it was for the first time...I just put a upgrade in it this am..a speedball kit which is a constant current source, more power supply isolation etc...Another step up...To me it sounds like a 10 out of a 10. A beautiful pairing with the beyers...and senns.AlexNote: I had a Lyr and LCD 2's as well!
Hi Guy!I followed your adventures with the Crack....I have several tubes I have tried and to tell you the truth their isnt much difference in them to me.They all sound good.I usually run a NOS RCA 6AS7G coke bottle and a RCA 12AU7 that came with the kit...I tried a EH 12AU7 but their is no real dramatic difference!!.The speedball upgrade made a nice difference, dead silent and very nice openess, sounstage, but I would have been happy withthe normal crack as well....but for $20 deal it was a no-brainer to buy and install.I like soldering and building and have built several DIY amps in the past...even a desktop version of the O2, my ODA by AGDR over at diyaudio.comI am listeng to to it as i type..still a wonderful amp for what it is, simple, so very simple...for high impedance cans.Alex
