Icarium Posted September 2, 2007 Report Posted September 2, 2007 There's a fan in the chassis?? I wonder if there's one in mine. I dunno my SDS with the tube complement i have now is really kickass. I've heard the Qualias out of a properly tube tuned Zana Deux and it was pretty damn good as well. I can't really cede a victory to it ;p The Zana Deux definitely sounds better with w5000s so far but I haven't really looked for tubes to optimize that sound on the SDS ;p But the SDS definitely sounds better for me with L3Ks (Though this was with the kenrad/sylvania 6SN7 tube complement which isn't super duper optimal for anything).
tkam Posted September 2, 2007 Report Posted September 2, 2007 He only put fans in the very early ones w/ the older toaster style chassis.
909 Posted September 2, 2007 Report Posted September 2, 2007 fans in an amp especially a tube amp, he supposedly doesn't do it any more, but it seems so counterintuitive. i can't even think of one instance where i've seen or read about an amp having a fan in it--very strange.
tyrion Posted September 2, 2007 Report Posted September 2, 2007 From what little I've heard, purk's "SE" version is a sonically step up from mine, especially with the R10. The Zana Deux is competing with my SDS, so I'm guessing that the SDS SE would be a bit better than the ZD as a headphone amp, though perhaps not for all headphones (Qualia?). This is the first time I've had a headphone amp in house, where (after at least a week of listening) I felt it was at the level of the SDS, with multiple headphones - besides Purk's SDS, of course. The noise floor is definitely higher on my SDS than the Zana, not sure about purk's, but the noise doesn't bother me. I'm a vinyl fan, remember? I think most of the noise floor is coming from the chassis fan's vibrations transported through the chassis to the tubes and exciting them micro phonically. Which bring me backs to the chassis - the big steel chassis looks awesome (IMO) and is a conversation starter for sure - but it's a terrible liability as a preamp because it's incapable of managing or dissipating vibrations. The ZD is an excellent amp for the Qualia. The ZD is an excellent preamp. I used it with my F1 for speakers and K1000. The biggest issue I had was the heat generated by both amps. I simply couldn't tolerate it in the room I am using now.
Icarium Posted September 2, 2007 Report Posted September 2, 2007 Yeah I can't even imagine using a ZD in a Cali summer. Let alone a florida summer. That is just... geh :/ I wish I had bought your ZD though Tyrion !

A few big power amps that use tubes like KT88s have fans in them.
909 Posted September 2, 2007 Report Posted September 2, 2007 didn't know, but what about headphone amps? any fans in headphone amps besides those earlier SPs?
deepak Posted September 2, 2007 Report Posted September 2, 2007 didn't know, but what about headphone amps? any fans in headphone amps besides those earlier SPs? No idea about headphone amps, I thought you meant tube amps in general.

That is just... geh :/ I wish I had bought your ZD though Tyrion ! Your summer is like our winter. It felt like the temp in the room would go up about 10 degrees from the rest of the house. The WA5 doesn't get nearly as hot.
909 Posted September 3, 2007 Report Posted September 3, 2007 No idea about headphone amps, I thought you meant tube amps in general. initially i did, but i'm also curious about tube headphone amps.
Icarium Posted September 3, 2007 Report Posted September 3, 2007 what about using the a/c? My parents conditioned me and my brother to believe that AC is for pussies. Unless we aren't paying for it ourselves.
humanflyz Posted September 3, 2007 Report Posted September 3, 2007 My parents conditioned me and my brother to believe that AC is for pussies. Unless we aren't paying for it ourselves. So true of an Asian upbringing, I had to LOL because my parents are exactly the same way.
909 Posted September 3, 2007 Report Posted September 3, 2007 crazy, how could you stand the heat or sleep comfortably without pumping the a/c? my folks always kept the temperature in our home around 68* during the warm or hot months and 78* during the cold ones. my wife and i like to keep out place pretty cool usually below 70* though not below 64* when it's cold.

I know what you mean, I got too comfortable with central air in my apartment. So now if it gets over 75 in my room I usually just sleep in the basement's (fully furnished) guest bedroom which is always really cool. I thought about moving my headphone setup to the basement lounge/game room just because it's so cool. But meh laziness (I was only home a month). I can't stand the cold, usually keep it at 78-80
postjack Posted September 3, 2007 Report Posted September 3, 2007 crazy, how could you stand the heat or sleep comfortably without pumping the a/c? Living where I live, every few years a hurricane comes through and knocks out the power for 1-3 weeks. You really do start to get used to falling asleep in a pool of your own sweat, but after you get used to it you get all crazy in your head. Like you sleep in sweat all night, get up and take a cold shower, and go to work and you're like, I don't know, crazy. I felt so insane in those weeks after Katrina, probably was the whole scene that contributed to it. Modern houses aren't built to take advantage of breezes, and this becomes a painful fact in southern alabama with no power in september. so far as temp I like it at around 74.
granodemostasa Posted September 3, 2007 Report Posted September 3, 2007 Berkeley has been in the lower 80s lately.... and dipping into the 60s in the night. but my place is always around 75ish... due to two factors: the way it's built and my zana deux at night.
postjack Posted September 3, 2007 Report Posted September 3, 2007 due to two factors: the way it's built and my zana deux at night. and we have come back OT, good job demdem.
mulveling Posted September 3, 2007 Author Report Posted September 3, 2007 my apartment should be a constant 67* Haha, same here. Hot-running tube amps, no problem - just crank that AC. So I like it pretty cold - but sophomore year college, I had one roommate in my on-campus apartment (4 bdr, 2 bath) that just seemed crazy. He's always turn the AC up to the point that I was fucking freezing, in the middle of a GA summer. He actually looked kinda like an eskimo, so we thought it was just in the blood...but one day we were in his bedroom and we saw he had all the air vents sealed shut with paper & tape (keep in mind HE was the one who always cranked the AC), so we all like had a major WTF moment right then. Seriously, Willis....WTF?!!!
postjack Posted September 3, 2007 Report Posted September 3, 2007 maybe he stashed drugs in the vents and cranked the A/C up to keep it nice and cool? what drug has to be kept cold besides LSD? an eskimo with LSD stashed in the vents, fucking awesome.
mulveling Posted September 3, 2007 Author Report Posted September 3, 2007 what drug has to be kept cold besides LSD? an eskimo with LSD stashed in the vents, fucking awesome. His dad was a professor there. I think it was physics, not chem, but still seems plausible. Wasn't LSD invented at GA Tech, or something?

Wasn't LSD invented at GA Tech, or something? If by "something", you mean LSD was invented at Sandoz Laboratories in Switzerland by one Dr. Albert Hofmann, then yes, you are correct.
deepak Posted September 3, 2007 Report Posted September 3, 2007 Creepy people do creepy stuff, I wouldn't worry about finding any logic. He wasn't a furry was he? Because that is some disturbing shit.
hungrych Posted September 3, 2007 Report Posted September 3, 2007 There's a teacher in my school named ms. albert-hoffmann.
