I would have gone for the Wyred except I decided to splurge and go for the BCref1000m2s for a significant premium.
The premium got me 100K input impedance compared to 60K and perhaps an upgrade in the on-board power supply.
I like the Wyreds as the best value overall though that are capable of driving the OHMs to the max and also mate well with most tube pre-amps.
So if you want to splurge, you can substitute the BC ref100m2s for the Wyreds in the equation, but you may end up with very comparable results with the Wyreds as well I suspect. Some reviewers have suggested an audible sound difference between the two, but I have never had the opportunity to compare.
And yes, I am a fan of the MErcury Living Presence recordings as well and they provide some of the most captivating sound available on a suitable system. A lot of those used very simple miking techniques combined with a focus on delivering a captivating stereo sound experience back in the day when stereo was a new and big thing. The OHMs deliver this in spades as they are capable of doing with most all very good recordings I have tried when driven to their max potential by an amp like the Wyred or BC Icepower amps.
I do not understand what the Icepower detractors are hearing to justify that position. The sound may not be to everyones taste (nothing is) but there is certainly no graininess or any other artifacts that people associate with anything even remotely digital in nature.
