I'm not sure if you read the prior page or just lept into the fray, but for context, my post was a continuation of a discussion on the previous page, responding to a question from hughkk about purchasing a transportable amp to complement his anticipated BH Crack - which I (among others) highly recommended and discussed with him at some length in the hd650 thread.
I suggested looking at the O2 as a semi-portable simply because (i) I "suspect[ed]" it measured better than two other options he was considering - which it apparently does; and (ii) it is cheap. If there's a reason you disagree with this suggestion - I'd be interested to hear it. In any event, I don't want to derail this thread any further.
I really appreciated your guidance in building my crack beefy, and I'm sorry my quip rubbed you the wrong way. I didn't mean to stomp any toes - well aside from armaegis', just a little.
Don't say "sorry" man, that's lame. You gave advice and your opinion, you didn't offend anyone and even if you did, it's your opinion, don't apoligize.
I don't know anything about electrical engineering and very little to nothing about audio but what I did notice during these first couple of months of browsing amps,headphones,sources,.. is that a lot of people aren't buying what they think sounds best, they are buying what other people are buying because it's supposed to be the best, earns you the most bragging rights and makes you feel special.
Apart from buying and building a CRACK, all I've done is browse amps/sources, you know, dream a little about what I'd get for when the upgrading day comes. When I read about the O2, my first reaction was to deny it and ignore it.. It simply isn't as special as any other amp that you can buy. I would rather have bought a schiit amp and DAC than look into the O2. Wonder what it must feel like when you actually own any of the gear that the O2 supposedly beats.
On topic: The hum is back .. what the hell.. my crack was dead silent for a couple of weeks, didn't use it for one week and now the hum is back. I swapped between my two 5998 and it's identical, I swapped back to my stock tube and the hum was superlow, it was still there, exactly the same but a lot more silent (to the point it isn't an issue anymore). I have noticed that volume is louder with the 5998 compared to the stock tubes. My gut tells me that the problem is actually the 12AU7 tube but that the hum is simply louder because volume in general is louder with the 5998, could this be correct?
Last time I had this problem (hum, volume independent), it was the 12AU7 tube.
Thx in advance
