I auditioned the LIVING VOICE AVATARS at a dealer
They were driven by CROFT separates [tubes], a DENSEN cdp, and cabled with an all top LFD cable array.
Lovely..... engaging ......full stop.
caution ...... the LVAs are finicky and perform at their best with a careful matching of associated equipment.
(1) The CROFT, DENSEN and LFD were a very significant step up upstream with a large multiple step up in both cost and build with an implied performance upgrade in lockstep, when compared to your QUAD
(2) I wouldn’t get influenced by their higher efficiency alone.
(3) If you can’t audition them personally then it’s a BIG roll of the dice (emphasis added ) with your current QUAD and your unspecified source and listening room acoustic warts.
FWIW .... I would not buy them blind .
