What you guys think of Parasound Halo C1, C2 or P7 preamp? I think they all have sufficient options for analog audio input & provides XLR output for the A51.
Out of these 3, is there any model which will do a better job than another?
I think with P7, you can not do room calibration using a mic. In that case wouldn’t a C1 or C2 would be a better option even though they are a bit outdated?
Also, how do they compare to Krell S1200U?
