Milos what's your scope/gear that you'll be using to measure your T2 when completed?
Hi,
I'm trying out the Stax 4170 system and can't detect any 'etching' in the mid-range. I'm not sure exactly what an etched mid range is supposed to sound like but the SR-407 headphones are clearly a step change from dynamic headphones. Compared to my previous Sennheiser HD 700 there's no excruciating emphasis of the treble so sibilance is not artificially emphasised. The SR-407 seems to produce a warm sound compared to my old Stax Basic system with no fatiguing treble issues.
However, for financial reasons I may end up buying a SRM-323S and SR-407 instead (after selling my HD 650 and Graham Slee stuff). Is there a very noticeable difference in the sound quality of the SRM-323S compared with the SRM-006TS? I've searched the forum without luck. Due to size of these amplifiers (compared to my tiny Stax Basic system) the SRM-006TS has to sit on top of my PC tower. I know class A valve amplifiers run hot but the SRM-006TS is like a radiator.
Thanks

Through ebay, I have bought from Japan a SRM-T1S (Japan version, 100v only). I have connected my Fiio X3 to it through the line out and it sounds great.
My questions are two:
1) I was sourced by the seller a 220V to 100 V converter but the Power is too low, it overheats and disconnects. I have bought a 220V to 110V converter. Works fine with it, and since I have seen that there is a fuse inside the amplifier connected to the main current plug, I assume that I run no risk (otherwise, the fuse would blow out). I understand that having a 100V converter would be better but they are extremely hard to source. So…. what are the risks, if any, I am running by doing this?
2) Thinking in replacing the SR-5, does it make sense to buy the 507?
Thanks!

Ya, I don't hear any difference when connecting a second headphone to my DIY BH. In fact, at meets I usually have had 2 headphones connected to it at the same time. It would be interesting to see the measurements produced by adding a 2nd headphone to amps with a high output C or low slew rate...I think the LL mk1 has something like 150-200 pF output capacitance and the SRM-T1 is probably pretty limited in slew rate. It would also be interesting to hear some subjective comments on the addition of a second headphone to some of these amps - is there an audible difference, and if so in what way?
