This is a timely posting from my perspective - I have a spare Wyetech Labs Opal pre-amp and Bryston 14 amp, and am contemplating trying some non-box speakers using these as a downstream combo.
The Avantgarde Unos (the much smaller siblings of the fancy Trios above) are one possibility. An internet search suggests that these speakers don’t pair well with s/s amps, and are better suited to lower power SET type designs. However, given the hearsay nature of the net, I’d like to ask forum members and James if anyone has first hand experience driving Avantgardes with a Bryston amp? (I recall that a dealer was driving Acapellas with Bryston to very good result).
Auditioning these isn't easy, so any thoughts are most welcome, many thanks.
