I don't know how much effect tuberolling will affect its sound, but it can be tuberolled. For instance if you want nice warm sound with more low end, stick an RCA grey glass 12SN7 on the input, and if you want to rock out to metal swap it for a GE 12SN7GTA. You can also use 6BL7's instead of 6BX7's which should also give a warmer sound. As for cost, if you want to do it for cheap and build it on a plank of wood, I'd estimate it can be done for about $150-$170. I'd think $250 give or take would make for a decent spec with an enclosure. Looser101 would be the one to talk to on costs since he's actually built one, if you can't reach him here hit him up on head-fi or bug philodox for his contact info.

Sometimes, I miss the blindingly obvious. Ok, we all know the K340 needs a really powerful amp, preferably, a tube amp. There was one sitting under my nose all this time. Now, this does require sourcing parts and soldering it all together, but all the parts are readily available. Behold, the Aikido Headphone Amp, and yes you can stick high power tubes like 6BX7's and 6AS7's into it, and run nice cheap 12SN7 tubes at the same time. I've heard the version using 6CG7's and 6H30's, it drove my Senn 580 and Phil's K340 with no trouble at all. It was meet conditions, but I'd say it's quite close to my own tube amp, which is to say damn good. If you're comfortable with a soldering iron or know someone who is, build the Aikido, I'd take it over a Darkvoice any day. More details & assembly instructions can be found over at the TubeCAD website.

Well, if you're handy with a soldering iron or know someone who is, there's a relatively easy fix. Stick a 12V transformer in it or mount a jack for an external adaptor and have it run 12SN7's. Snip the filament wires on the 6SN7 and solder new wires going to the new transformer or jack. Needless to say this voids the warranty so you better make sure the stock amp works first.

Judging from your impressions so far, I'm reasonable certain that the pair you just got is the bass lite version, while the NOS pair is the "neutral" one. The bass heavy version which I have is seriously rolled off in the treble and a lot slower and mushier sounding (when stock) so I'm quite certain it's not the one you have. Still nice, but christ is it ever a pain in the ass to tweak, it still shares the K340 family sound but it doesn't have as much potential goodness when it comes to modding. Now you just got to get one more and you'll have the whole K340 family.

Sounds like you got the stock version of the one philodox has, I think that's the best one out there. Also, since you're getting a 2nd pair, will there be any plans to mod one of them?

How much difference does cables make in your system?
aerius replied to deepak's topic in Audio Accessories
In my system it barely matters, if I had to take a guess it's like the last 1-2% or so, chances are I wouldn't notice it 95% of the time. Why? I don't know, maybe my gear just doesn't care about cables. Strangely enough power cord changes are pretty darn obvious, but that's getting off topic. -
Since I don't have to mail-order it, my personal favourites are magnet wire and Cat6 network cable. Sometimes I'll also use RG-6 TV cable, I strip off the outer coating and shield and use only the inner wire along with its thick foamy insulator.

Pretty nice capacitors which I don't think are made anymore, said to the be 2nd best after Teflon. Available only in small values under 1uF as far as I know, mostly in the pF & nF range. Generally found in phono stages & pre-amps.
-
There was another company other than Solen which made large value film caps, can't remember the name though since it's been a few years. My personal cheapskate solution is to use motor run capacitors which can be found on ebay as well as industrial supply and airconditioning places. The one downside is they're bigger than the Solen caps, a 75uF cap is about the size of a Coke can. As for Blackgates, they might be better than a standard electrolytic cap, but in terms of performance they ain't anywhere close to a film cap. We're talking orders of magnitude, not little dinky percentages here. Electrolytics are evil, kill them wherever you can.

Your genitals. You don't want all that radiation, RFI, EMI, and all that other stuff frying your most valuable of valuable parts do you?

I've heard nearly their entire range except the Evidence series, other than the Special 25 I can't stand them. It's like they took the worst of the Senn 580 and AKG K701 and made a speaker out of it, to me they're veiled & dead sounding while at the same time managing to be harsh in the treble & lacking in detail & resolution. The top speaker on my list would be the Living Voice Avatar, it looks like a blocky piece of crap but it's ridiculously good. Very high resolution, clarity, & detail, yet it remains musical and will not make sub-par recordings sound like crap, everything sounds good. It's slightly rolled off on top compared to say, a Wilson Benesch, and the bass doesn't go down to 20Hz, but everything else is top notch. Was my reference speaker for perfect sound until I heard the Avatar OBX-R. Another choice would be the Opera SP Callas, which is good enough that it can be mistaken for a Quad ESL57 if it weren't for the bass. Not quite as detailed, dynamic & fast as the Avatar, but ridiculously good for what it costs. Haven't heard the Diva yet, but I'm guessing it would be a warmer sounding Avatar based on my listening experience with the Divina & SP.

Bit of an AKG buying spree: electret-dynamic systems on the way
aerius replied to deepak's topic in Headphones
There was a Darkvoice at the last Toronto meet, I don't know if you got to it before it died. I gave it a couple minutes of listening but the channel balance was completely fucked so I can't make any real judgements on it. Maybe. I think it does just fine at low volume, much better than my Senn 580 or Grado 225. But that's out of my amp which I've custom tuned to the damn thing so results may vary etc. etc. -
Cool, so when are you two getting married?
