Quote:   I am curious, if small amounts of jitter make no audible difference then what is the most likely explanation for audible differences between different digital interfaces (Coaxial, Optical, USB)? I have personally observed that an Audio-GD NFB-10SE sounds somewhat drier and...

I do find it curious that so few head-fi orientated DACs and amps come with published THD figures. If they did, then surely there would be a easy way to bypass a lot of "it sounds great / it doesn't sound that great" back-and-forth threads, just compare and see which has the most uniformly low...

I used the E9 with the HD650 and thought they weren't likely to improve further in terms of definition with different amps. Moving to a Audio-GD 10SE balanced setup improved the bass impact and integrated it better with the music, but left the clarity of the music as a whole unchanged (still a...

I've tried the iBasso PB1, Fiio E9, Audio-GD 10SE and RSA Hornet with the HD650. Ranking in order of preference: 1. RSA Hornet. Wonderful clarity, can pick out instruments with ease, voices have no grain and sound natural. Bass impact is a little lacking compared to the 10SE but not weak or ill...

I was wondering whether you've been able to compare the single ended input from your Pico DAC with balanced input from the DB1 into the toucan since getting your phones reterminated for balanced?   I'd be really interested if yourself or anyone else has been able to evaluate what differences...

Quote:   Why do you think this was? What was it about the DT990 pads that fixed the issue do you think? I've recently ordered a pair of the new DT770/600s (with velour pads) and I certainly don't want to be stuck with the excess bass, so if just ordering a different pair of pads will fix...

Has anyone with the Boomslang DB1 and PB1 compared using the PB1 with the balanced input from the DB1 and using it with a single ended line in from another DAC? I'm interested in the difference having a balanced source makes when using a balanced amp. A blind test would be fantastic - you...

Thought this might be of interest: http://www.headfonia.com/ibasso-pb-2-first-impression/   PB1 vs PB2: Quote:   PB2 with balanced IEMs: Quote:   Conclusion: Quote:

I take it then that with the PB1 and the HD650's the bass was truncated at the same passage? Quote:

  Quote: Does the extent of the improvement vary depending on what headphones you're using? In other words, is the improvement more noticeable on some of your phones than others? I'm most interested in the difference it makes with the HD650.

Does anyone have any more impressions of the PB2 compared to the PB1?

Quote: From my extensive headfi reading the only firm conclusion I've come to is that the only final word on whether amp x can adequately drive phones y is by reading people's experiences of using the combination. That said there is often suggested headphone impedances given in the amp...

Quote: I'm ordering the DT770/600 and have no plans to get the DT990/600 because it is the same as the DT770 except with an open back instead of a closed back. Personally I don't see the point in having more than two headphones in regular use, one for home and one for work.   

  Quote:   I'm curious, which do you prefer out of your UE SuperFi 5 Pro and the Beyer DT 990 600 ohm? I've previously owned the UE Superfi 5 Pro and I'm ordering a pair of Beyer DT770 600 ohm phones.   For the record, I'm going with the PB1 (using the balanced out) for my new...

  Quote:   Sounds better with which headphones? I can understand why moving from the PB1 to PB2 will make a big difference with very hard to drive headphones (like the AKG K1000) but any phone that is already sufficiently well powered by the PB1 won't necessarily benefit from the extra...
