The project was a lot of fun and I must say that your directions and packaging are as close to perfect as anyone can imagine. Please keep me posted about your emerging products.
I just finished auditioning the SC-1mk500 with output transformer. I recorded a Taylor acoustic with a Neumann TLM-193 into your preamp and then into a Tube -Tech CL-1B compressor. The results were fantastic. I couldn't believe how much clean gain was available. Not sterile clean, it does have "character", but clean! Solid lows and a sweet sparkly top end, it captured the Taylor perfectly. If I really hit the strings hard, the preamp could handle it easily.---My wife came in and she agreed, which is always nice, that the SC-1 sounded wonderful and was worth the expense. I won't hesitate to buy more modules and I'm already gearing up to purchase the package of three. You make a really great-sounding pre.
I own a couple of your SC1 Mk2 preamps which I put in a custom made case. I am thinking of buying a few of the MK3 version. Thank you for creating and offering these preamps. They are just ideal for classical recording, every bit as good as my [high end preamps]. - D.Rumley, USA
