I found it had strayed much too far from the "wire with gain" model for my tastes. My view is that an amp should, above all else, but true to the source material in terms of speed, dynamics, punch, detail. Both the Taurus and the V281 do this very well, but differently. The 430HA does not - it is slow, veiled and soft. It can be very engaging and entertaining with the right genres of music, but it just fails as am amp for me. Build quality and functionality are superb, but that was irrelevant to me as the primary function of the unit as an amp was compromised. As always, YMMV.
After being disappointed in the 430HA, and unhappy with the brightness of the Taurus and its inability to drive the HE6 properly, I did some more research and took a chance on the V281 and have been very happy with it. Powerful, detailed, dynamic and with a touch of warmth that the Taurus lacked. Perhaps not quite the same level of iron control of the bass as the Taurus - it can get a little bit "boomy" - otherwise an excellent amp.
