i won't say improvement but rather the change in signature is much greater than that of rolling op-amps. changing tubes can sound like you're changing amps sometimes.

technically that's the idea but getting tubes isn't that easy here. I import them from UK, and how many tubes you are you going to have to try, just to find your perfect signature?

but what i feel is that for that one amp, by changing tubes, i can match my amp to different kinds of headphones and iems.

This is the V2 now... even better.

do let us know what you think of the pairing with DT880 and the TTD as a whole.

hahaha i saw it, but i was waiting for you reply, since you're a dark voice / la figaro user.

he did try it before. but he didn't like it all that much, as i recall.

different signature preference.

can tell from his hd650 + symphonica + lavry da11 setup, which is very different from akabane's wood and yamamoto setup. i'm somewhere in the middle, biased towards akabane.

the darth beyer mod is for dt770/80 only.

600ohms lah! since you have darkvoice to drive

FaezFarhan: received your TTD yet? how's the pairing with your dt880? i really need to find some senn users for the TTD

i'm waiting to see if there's gonna be a dt880 replacement - T80

100hrs for the tube to stabilise but about 250hrs for TTD to really starting singing.

leaving it on without playing is not burning. at best it can be considered a warmer. the TTD actually is pretty cool for a tube amp. larger ones get even hotter.

if you want slightly more bass, the GE/sylvania tube is a possible option. i will finish burning the amperex tube tomorrow morning, and will then switch over to telefunken.

Quazacolt: hahaha imo, tube doesn't go with AT-AD series. unless you just want the mids to shine while giving up treble and bass, like the woodies. for you, give the meier concerto amp a try, its a SS. i think your taste runs that way.

meier concerto? Jaben KL carries it. and i knows a guy in KL running his HE-500 with the concerto amp.

Added on December 6, 2011, 11:53 ami just play music through it. my TTD v2 has been running 24/7 since i got it 2 weeks ago. i've yet to turn it off. so far its like 24hrs x 16days already. but use it in a well ventilated area and all the common stuff. not buried under a pile of paper in a drawer...

hehehe it sounds much better than that writeup. but its good that you've auditioned it. hahaha i'm more familiar with tubes and concerto is one of the few SS amps that i've auditioned. & i prefer concerto to lavry's amp.

ahhh ok. the concerto is a pretty good amp. i do find it a little on the drier side, but nothing that a good pair of copper ICs can't solve.

which headphones are you referring to?

around rm2k i think. check with jaben.

well, after that you can drive the T1 with the concerto. and that's a 2k amp driving a 5k headphone.

what is your dt770 setup now and what are you looking at to improve? which version of the dt770 are you using? 32/80/250/600?

i think if you want to tighten the bass, its more worth while to get a good amp than to do the mods and increasing the dampening.
