Just wanted to share some measurements I got from my new KEF R11s.
mic at 1 meter in room with all reflections active.
REW measurements, MacBook to Mytek DAC+ to McIntosh MC462 vs. to Wyred4Sound (W4S) ST1000 (ICE 1000ASP) low (RCA) + MC462 HF (XLR) bi-amp. Using XLR out to the Mc and single ended to W4S. Bi-amp has about 1-1.5 dB more gain in the low end. Using 4 Ohm taps on MC462.
I thought I could here a difference when playing bass heavy pop. However, I did blind testing and it was a wash. Here are the measurements.
Overall, these KEFs are amazing, only give way to my previous active set up at extreme SPLs.
1st Mc462 alone
2nd MC462 + W4S bi-amp
3rd MC462 alone distortion
4th Bi-amp distortion
PS: compared to KEF R3, the bass distortion is commendable.
Also look at the noise floor, much lower with McIntosh.
