There is a thread on the Slim Devices forums re the SB+ that you might find interesting.
Patrick Dixon, the designer and manufacturer of the SB+ is a regular contributer to the forum over there.
From the fotos the SB+ and its matching PSU look to have a very professional build quality, unlike the homemade look of the Bolder mods.
Patrick has a long history in electronics design and seems to know what he is doing.
On that thread 2 guys are getting together to compare the SB+ V the Transporter.
The review you referenced was originally to be a shootout between the SB+ and a full modded Bolder SB with ultimate PSU but apparently there was some malfunction in the Bolder unit so it became a review of the SB+ only.
In the US I would suspect it might be easier to check out the Transporter. It's the most musical digital source I've had in my system.
(I prefered it over the Bolder full mods)
I found it to rival the Ayre in my system.
As usual, YMMV, IMO etc.

I listen to the TP with xlr outs.
