Hello all, thanks for interesting posts :-)
I have now auditioned the PS Audio BHK Signature for about a week, and I think it is an amazing good preamp. Actually, in my ears, and in my gear, it is the best preamp I have ever heard related to price!
It is so close to my BAT VK-53SE on many parameters, costing 40 % of the BAT :-O
It is inferior to the BAT on the following areas:
- Resolution (but only slightly)
- Bass extension (I assume it rolls of 3-5 Hz higher up than the BAT which goes VERY deep, I guess that for most loudspeakers this will not be noticed)
- Macro dynamics/slam
- Harmonic tone structure (if that is the correct English words to use), (noticed on piano, big string instruments etc)
- Soundstage depth (but only slightly)
Conclusion:
The PS Audio BHK Signature preamp is a bargain and highly recommended! It sounds musical and natural, and presents all kind of music in an engaging way.
PS
I tested the preamp with Mullard NOS tubes (1958), which was an improvement relative to the PSVANE standard tubes.
