iBasso products are (IMHO) quite nice, their size, and the SQ has been a boon to my hips.

I wish I had known the 180 degree turn in the size of the D1. Seems my left side has formed a dis-symmetry to my right.

Hopefully, their newer amp, when it makes its Ta-Dah! appearance will have most of the features of the D1, and be less massive than the lead brick that is the D1.

Trans-portable, but not, by a stretch, a comfy portable.

The sound, however, makes me smile.

Looks like Headfi is back.

So, more impressions?

What is the difference between the LT1364 and the LT1361? I have a whole bunch of LT1361's I want to try out.

Also, does anyone know if the LT1122 is safe to try out in any of the slots on the D1?

Check this datasheet for the LT1122. Especially the supply voltage. That should answer your question.

I have a few extra LT6234 (un-mounted). I am looking for a pair of LT1364, does anyone want to trade? Send me a PM. Thanks.

BTW, I have been trying the LT6241 w/ LHM6643 as buffers. It is a hard call but I may go back to the AD8599 w/ LHM663 as buffers.

I think I'm going to try out the LT1361's and 1364's.

Do your D1 chargers emit a high frequency noise when plugged in?

 

[jamato8]

Mine doesn't. Do you mean from the charger or a high frequency sound out of the D1 that you hear in the headphones?

 

[itsborken]

FWIW, I've gotten that high frequency sound out of the charger occasionally. It doesn't seem to matter.

 

[Schalldampfer]

Out of the charger. And it seems to be consistent, too.

I've noticed the charger influencing sound quality after I've had the cover off to roll opamps. It seems that if the metal sheath of the charger plug is too close to the metal of the back plate (as is wont to happen) there will be some sort of feedback in the audio output. I find that the feedback goes away if I jimmy the back end of the board to one side, so that the charger port is centered within the opening in the back plate.

I've stayed with the AD797 x2 in LR, AD8397 x2 as buffers, and LTC6234 DAC since 11/5/07 - I have no desire to change anything now

 

[jterp7]

has anyone received the updated version yet?

I will have that setup soon except with the LMH6643 in the DAC position

. Happy to hear that it is doing great.

I received mine on 20 Nov. Still in the burn-in stage. To my untrained ears, it sounds pretty good. Yesterday, I switched from USB to optical input from MacBook Pro. I think I am hearing an increase in the upper registers. Extremely detailed with HD-650s.
