I'm done with my studio for this year. Here's the Lindell 6X-500 preamps in their A Designs powered rack.
No, not the world's most awesome color-combination (brown on cream).
I recorded some acoustic guitar with the preamps (boosting a little 6K on each channel just because I could.) The Lindell Test is at 96kHz, the Anubus was recorded at 48kHz. I downsampled them both to 44.1 based on the theory that such an obnoxious downsample would adversely affect both of them about equally.
I threw both of the signals through identical non-linear summing plugins. Obviously, the performances are not identical because that would be impossible for me to do.
