Quite a review on this preamp. It uses Lundahl and Jensen transformers. The lundahls especially the amorphous core transformers are very transparent. I like the ground switch,shows good design as this option can and will effect the clarity. At 8K this preamp was probably a steal,twice or 3 times the price less so. It has all the sonic markers of a great preamp. I don't think,low gain is needed for this level of performance,but again that's just my opinion. Someday I will listen to this preamp.
I did a little research later on the web and found this by Steve M. commenting on the transformers:
"I now use Lundahl amorphous-core transformers in my amp upgrades (and in my VRE-1 preamp). I started with Jensen transformers, but switched a few years ago when I found the Lundahls offered better transparency. I originally used input transformers to provide a balanced option, but I then found that I preferred the sound of my amps with them, regardless of which input (balanced or unbalanced) I was using. First of all they provide complete immunity from DC and RFI, and well-designed units have outstanding common-mode noise rejection (CMRR). This allowed me to simplify my amp's input stage, and the net result was sound that I hear as cleaner, clearer, smoother, and more "pure" if you will excuse the expression. And keep in mind that my design handles both balanced and unbalanced signals via the same path (the only difference being the input jacks) so you get the benefit of the transformer either way. Of course this only works well with great transformers, but that is the only kind I use ;-)
In short, I feel the input transformers are a sonic benefit even if you use only the unbalanced inputs. The only downside is the relatively low 10KOhm input impedance, but this is an issue with only a small number of preamps."Best regards,

You'll notice Steve M. talks about RFI and CMRR,very important for the kind of transparency that his preamp exhibits.
Just my opinion.
