iBasso confirmed that the charge rate through the USB cannot keep up with the operating current and that the battery slowly depletes.   When I asked them about the rolling kit - they just said to swap over components - not really helpful, since I am not able to identify the alternatives.  ...

I thought that lossless encoders were just that, bit perfect representations of the CD or source.  I got into a bit of an argument with a Naim user who had 'perfect rips' of the CD's onto their hard drive. He claims that the output of that system compared to say, the FLAC output of a Rockbox'd...

I did a couple of days of burn-in and compared sources again. Added to the mix was a newly acquired iRiver H140, with Rockbox, via the optical line out.   Using the DB2/PB2 with ipad/adaptor/usb and the iRiver H140/optical outputs - I was surprised, for the same source file, to detect a...

DB2 also works with USB camera connector and an iPad. Comparisons with the iPad sound direct to the headphones was a little surprising. In the brief time I had to compare, the two results were quite close.  I need to do further work to find out if the iPad output via headphones is good, or if...

Just go the little beastie from China, complete with a balanced jumper.  I have only had enough time for first impressions of the DB2 with the PB2, using Grado SR225i and Senn HD650 phones (the later balanced).   I compared to my reference Sugden CD/Preamp system output - the DB2 took a...

Thanks for the info folks - I'll take a look at finding some RS1i's or 2i's.  I note there seems to be two different versions, with and without a wooden button in the middle - is this just cosmetic or should I be looking out for one version rather than the other?

OK- I'm game - what's a 'woody'?  Do I get a lathe and turn myself some ear bowls? Chris

I have SR225i's and wondered about upgrading within the Grado family - especially if I could increase the overall warmth of the presentation a little - My 'phones are run-in and whilst they compliment my balanced HD650's, covering many recording balances - the difference is a little difficult to...

I checked with iBasso today on my DB2 order. They waiting for PCB's and should be shipping from the 15th onwards   regards Chris

thanks for that - I don't think I would have anything quite as big as 320Gbytes, more like 32Gbytes on an SDHC card. Are there any alternatives - apart from out of production items, that are compact audio players with digital outputs? I have done several searches without much success.  ...

I'm not sure if this should be in this forum, or the portable source forum but I'm thinking of buying a Squeezebox touch to use with an iBasso DB2/PB2 combination fed from it's digital output.   I'm working on the premise that whilst I am at home, I can stream from my network and use SD...

Part III with the iBasso PB2 - comparing AD797 / BUF 634 with OPA627BP / BUF 634 in balanced mode with Silver Dragon cables and Sennheisser 650's. The source was an iPod 5.5g with a Kimber dock cable.  The date code on the OPA627BP was 9820WM5016 and measured 50-60Kohms between pin 1 and 5...

After about 50 hours burn-in I evaluated the Silver Dragon balanced cable on the HD650's against the stock single-ended cable on the PB2. Gosh what a difference! - and not in the way I expected.  With AD797 and BUF in place, I evaluated the two configurations back to back. In balanced mode, I...

Silver Balanced HD650 cables and OPA627's should be with me for the weekend and I pre-ordered the iBasso DB2 today - proceeds to Japan. Do I need to run-in IC's?  I thought it was capacitors which were the main reason for burn-in? regards Chris
