@tvad Thank you for correcting me on the transformer-coupled balanced outputs. I forgot about that. To add more, there are both the single ended outputs and this pair of transformer-coupled outputs, but a switch is installed to toggle one or the either. Vlad mentioned he cannot bypass this switch and enable both outputs without sacrificing sound quality.
Your right in the sonic signature of his preamp, and it was a nice change from the preamp he offered many many years ago, which had less bloom and was much more etched and sterile in comparison.
