Hi Stan,
I'm happy to commit myself, I got my board today after a commercial friend installed the components for me - I'm useless with a soldering iron and don't know what I'm doing electrically - and I'm very pleased with the result.
First a minor point for others doing the mod: IMO the coil should be installed bent very slightly inboard as mine, fitted with the base flush to the board very slightly fouled the neighbouring PCB - note: it did not stop the board from seating properly but there is definitely contact between coil and board when the board is fully seated.
The words that spring first to my mind are realism and detail, better focus. This was very noticeable when listening to red book CD FLAC rips through headphones direct from the HP socket on the B-DAC. When the signal was routed from B-DAC fixed output to headphone amp the improvement was similarly noticeable.
When I tried Hi-Res FLAC playback there was also an improvement compared with the same path pre board mod but it was not so signifiant as for Red Book rips.
I have not done any listening through speakers yet but can think of no reason why the improvement should not be as noticeable - I'll let you know
.
FWIW another member of our threesome who followed the same mod path has found similar improvement but as he's more 'golden eared' (and 'golden tongued') than I am I'll let him post his own report, hopefully shortly
.
The third member managed to be out when the postie delivered his mod'd board so his findings are still awaited.
Dave.
