Hi, I had a chance to audition the Shigaraki and 25 wpc gaincard . I found the 25 wpc gaincard to be far superior. I also had the Audio Zone Amp 1 and at 45 wpc was very impressed. The Shiaraki build quality is poor and had a loud hum when I played my tuner through it. Hope this helps. Art
Art, Can you comment on Audio Zone AMP-1? When compare to 47 lab's 25 wpc gaincard, do they each other sound close? AMP-1 offer a substantial low price, half or 2/3 of the 25 wpc gaincard's cost. It would be interesting finally someone catching up.
