Hi Agsain Johnathon
It was a Mac-Mini using Audirvana Plus direct connected to Mac 501's into Lenehan ML3 Reference. You quite possibly know of the MAC's but probably not of the speakers. They are lined with steel to reduce resonances and use nothing but Duelund VSF Copper capacitors in the crossover. Each speaker is individually hand tuned for the best frequency response. They are ultra accurate, ultra revealing and are the fastest sounding thing I have ever heard - they for example blow B&W 802D's out of the water (not hard - I have seen the frequency response of those - without going into the details YUK). I am biased though because they are the speakers I have.
As I said everyone who has heard it noticed the same thing - it benefited greatly from up-sampling.
I am having someone over tomorrow to check out my Off-Ramp and if we get some time may be able to do the test again with a fresh set of ears.
Thanks
Bill
