The BS5 Encore fortunately is much less than a PC, it has no cooling fans and no hard disk, both very poor for injecting noise onto the DC supply. It's this noise which unstabilises the power supply and is reflected in clock variation, which in turn manifests itself as jitter on the output. There seem to be two ways to tackle the issue - clean the power supply inside the player or, if I could obtain a USB output then this problem is negated as the clocking is asynchronous, ie is applied outside of the players environment.

The Stello U3 is limited to 24bit/192 kHz. You may want to research DIY devices that can do better - exaU2I USB to I2S interface and a Buffalo or AckoDAC.

You may need to do some further research regarding PCs for audio use. Fanless is trivial as is the use of a system SSD. One can easily make a PC with much lower electrical noise than the B&O. Unless you specifically like the styling or badge there is simply no technical reason to go for it.

Well, I politely disagree about the fans, (having witnessed the 'scope, see SoTM), SSD helps but still requires thorough PSU filtration to remove the damage caused.

The dilema with the B&O kit is exactly as you mentioned though, technically I can better it from almost every aspect with other kit that's on the market...

HOWEVER, B&O have the MOTS playlist feature which, in my experience, having owned a variety of systems including the Sooloos, is the most desirable button to have for a music collection. The Sooloos Focus/Swim combo is very good - but relies extensively on accurate metadata which may or may not be in place depending from where you have sourced your music... The MOTS ignores this and refers to the individual track itself.

To highlight the difference... I have a Poison album on the system. I would classify Poison as "Rock" genre, maybe even put it into the "Uplifting" category - so, if I wanted to listen to Rock or if I wanted uplifting music then the album would be included in my playlist. However, on the same album there are a couple of fantastic ballads which would really be better listed under "Ballads" or "Romantic" categories.

So, one would need to go through every one of the 7000+ tracks and categories each song appropriately before my playlist facility would work correctly... or, I could use MOTS which does all that for me whilst I drink tea and chill out...

The challenge now is to combine the MOTS facility into a media player that sounds excellent with reference levels of minimised jitter etc...
