http://www.kenrockwell.com/apple/iphone-6-plus.htm#measurements   Seems the performance is quite remarkable, basically eleminating any need for a portable DAP.   For comparison, Benchmark DAC1 HDR measurements:   http://www.kenrockwell.com/audio/benchmark/dac1-hdr.htm#measurements

  There is still a long way to tP :)  (Planck time)   Give me one of these (with more bits) :)   http://www.researchgate.net/publication/257672452_Implementation_of_Six_Bit_ADC_and_DAC_Using_Quantum_Dot_Gate_Non-Volatile_Memory   Quantum Dots are small, must be good for portable u fink...

O.O   http://www.audiocominternational.com/latest-news/2014/01/new-37-femtosecond-jitter-clock-for-sabre-es9018-dac/

So, um, anyone here tried the MSB Diamond DAC IV Plus with 77 Femtosecond Galaxy Clock? :)   http://www.msbtech.com/products/dac4diamond.php?Page=dac4home

I ended up picking up Arcam rDAC-kw on ebay with wireless dongle. Sounds great and wireless sounds lossless to me as advertised. No trouble connecting.   Dual wm8741 dacs, dCS anti-jitter tech. Original price was $700 i think, now discontinued.

  I suggest one of these bendable cable tie brands:   "Gear Tie" (a bit more rigid) http://www.niteize.com/product/Gear-Tie-3.asp   or "Flexi Ties" (padded, soft) http://www.amazon.com/UT-Wire-Reusable-Organize-Yellow-6-Piece/dp/B003P9W0RE

Loving this track on my TH-900 :)   https://www.youtube.com/watch?v=1D70nk6Datg

Btw just for the record, TI TPA6120A2 is not an opamp chip, it's an actual single chip end-stage amplifier that is intended to be connected directly to headphones (Stereo Hi−Fi Headphone Driver according to TI diagram). The card uses 4 more fairly high end opamps for pre-amplification.

>> That is, unless he is specifically determined to play the T1 game, rather than enjoy music.    I want to like the T1, i love the design and how comfortable they are. It's a beautiful piece of audio equipment. So I actually want to make it work and sound better than the TH-900 :) They are...

>>if you cannot afford a proper amp   So you are saying my amp is not great but if you look at for instance   http://www.wooaudio.com/products/wa22.html   Signal/Noise: 92 dB THD: <= 0.3%   While ZXR amp's THD is 2000x lower (!) and S/N is 120db (28db higher which is enormous), so I...

  Hmm, thanks for the reply. Perhaps i should give it a shot with a stronger amp. I don't understand why it should matter at lower volumes though?

ZXR has a specific setting for 600ohm headphones and is using TPA6120 amp rated at 80mW into 600 ohms at 0.00014% THD+N (!!!) and 120db S/N:   http://www.ti.com/lit/ds/symlink/tpa6120a2.pdf   Also note SMPTE of 0.000095% (!)   So i think its more likely the headphones since the technical...

I guess they don't sound horrible but they clearly can't resolve nearly as much detail as the TH900. So for instance I'm listening to M83 Dead Cities, Red Seas & Lost Ghosts, track 2 (Unrecorded) at around 3:00 there's a lot of intricately layered high frequency synth that T1 just doesn't seem...
