Saturday. They are testing the first batch right now.

Does rolling opamp increase/decrease the power output?



Well it depends upon what you use for the opamps. You should be able to increase the power output but of course with a decrease in battery life although there are some opamps that you could use and still get good battery life. You could bypass the buffer with a jumper and just use the opamps. There will be many options.

Sounds like fun all over again as with the D1 but with a new and improved model and smaller!

Exactly! So the rated 100mW is only applicable to the opamp that is pre-installed. However, swapping a different opamp can increase power with a caveat that it will decrease the battery's life.

Some quick comparisons of the D10 vs the D1

D10 uses mostly the same chips as the D1, with the exception of the D/A, where the CS4398 in the D1 has been replaced by the WM8740 in the D10. D10 is defintely the more portable package, being half as heavy and abt 50% slimmer. It has some new features not present in the D1 - impedence selection, charging on/off switch.

Price - $290 vs $230 for the D1. What has gone into the $60 jump?

Sound quality - we'll have to wait for the 1st reviews - can't wait for Jamato or HiFlight to start the op-amp rolling!

D10 Specs
- PCM2906, converts USB into a S/PDIF signal (same as D1)
- CS8416, DA-receiver chip (same as D1)
- WM8740, D/A chip (vs CS4398 in the D1 - which one is better?)
- OP+BUF structure for amplification, (same as D1)
- 2-Setting Gain Switch for impedance matching (+3/10dB)
- Dedicated MCU (Micro Controller Unit) to manager inputs, outputs, and functions. (same as D1)
- Flexible input and output compatibility. It has USB, optical, coaxial, stereo input, line out, and stereo output. (same as D1)
- Works as a combo or a stand-alone AMP, DAC, USB soundcard (same as D1)
- Built-in rechargeable Li-polymer battery plays up to 30 hours (30 hrs for AMP, or 20hrs for combo) (D1 wins - 40 hrs for AMP, or 20hrs for combo)
- Measures 55*21*104mm, and weighs 168g (D10 wins - D1 is nearly 50% bigger and twice as heavy - measures 78*32*120mm, and weighs only 320g)
- Comes with power adapter, leather pouch, optical cable, USB cable, warranty card, owner's manual, and opamp rolling kit. (includes AD8656*2, LMH6643*2, Dummy adapter*2) - (largely similar, apart from the additional opamp rolling kit for D10)

So who'e pulling the trigger? The form factor does seems very attractive for iRiver H120/140 combo.

* I may be tempted by the slim form factor and battery life because my PCM1793 DAC is rather longish

Well, the price has definitely go up by quite a bit - $290 vs $230 for the D1 when it was launched. But hey, if the SQ is good, I'm sure many will spring for such a portable DAC with many input choices.

I'd say it's still a fair price. The D1 is still available new from AudioPhileChina and they demand $279.00 - considering it is a tried and tested Amp/DAC I am not surprised.

But if this D10 were to be coming from RSA or Qables or HeadAmp or Meier, even if priced over $350 people will still pull the trigger without even blinking. Yes, brand name still play a big role in purcshase decision

The price is $275 not $290. It is a little smaller than my iRiver H140! Woo hoo, what a combo. I hope. :^)

Last I heard from iBasso in November the D10 amp section wasn't quite as good as the D3 yet, which they felt was their best effort (as does Skylab) - they said they were working on improvements, which may have lead to the decision to socket the opamps and buffers so it would not be limited to how good it can sound.

I felt the D1 was very good with AD797 or AD743 in the main amp, and AD8397 or LMH6643 buffers, and LTC6241HV or LT6234 in the DAC (and sometimes AD8656 in DAC). It was limited more by it's USB DAC performance, while the optical performance was better (more air and space and ambience and micro-detail).

I am disappointed that they didn't do I2S from USB receiver to DAC like the D2 and D3 models, and stuck with S/PDIF.

The price seems fair to me.

I really hope the build quality of this thing is good. Of course components fail and that's life, I understand that. However, I've read more than a few people complaining about issues with previous iBasso products. Hopefully iBasso have looked at what has and has not worked with their previous products and made this as robust as practical.

I dont mean to sound negative. Its not exactly cheap sending stuff back and forth to China.

Email them and ask them why they didn't change. It might be interesting to know. I mostly use optical so I am not very much effected. On the RCA for a coax input it should have been a BNC as that would be a true 75ohm connection, which is what you want for digital reflections.

On the sound they stated to me that the soundstage is slightly narrower than the D3 but that is with the stock opamps. What it will be after opamp rolling is anyone's guess.
