Hello Sunnyboy,
Wonderful! system you have put together.
No doubt music through your Quads is fabulous to hear driven by Conrad Johnston electronics.
As a long time Quad owner myself since 1984, I quickly realized their strengths Upton first listening to music through them back in the early 1980s.
Shocking natural sounding timbre with acoustic instruments and life like vocals were immediate with the Quads with good recordings.
I listen to Jazz ,Big Band, folk, Rock and some orchestral.
Through out the years I have always used two different pairs of speakers and electronics depending on my mood for music type.
I still have my Quads and do use them on occasion and just up until recently used a pair of Dynaudio Anniversary Special 25s I bought in 2004 for listening to Rock, Orchestral including some of my Jazz collection and Big Band music for sure.
A beautifully made small musical speaker with a big sound, plays loud and sounds best driven by vacuum tube amps.
A gift at a used price if you come across a pair for sale.
Something to consider for a Pink Floyd fan with Quad speakers.
