I have > 5K trouble free hours of blissful listening on my Ref 5se. Some PL experience but not ownership. In another thread, i am a self admitted fan boy cult member…ha. One could accurately say i fall into that camp with ARC preamps… but i have also had on long term loan a few other excellent preamps..notably Ayre R series, VTL, Lamm, ….
I think an inside track on a well cared for known REF5se is worth something…
On the 5se, budget or plan for a 6550 in the power supply every 1k hours and 2-3x that for the 5 small signal tubes. Just FYI.
