The reviewers Hirokazu Shinoda / Iori Yoshida use Airtight ATM-3211 to compare with Sun Valley SV-S1628D. SV-S1628D is a big bargain..
It is very nice to be compared to a product that is 98% more than SV-S1628D.
Here is the comment from Mr. Hirokazu Shinoda / Iori Yoshida
This Amplifier provides transparent, uncolored and dynamic and reproduction; the strings are clear, vivid with remarkable sustain and inherent overtones. The design of the 211 incorporates a self-biasing function consistently yielding rich, natural and expressive power, making this component even more outstanding.
