I must work again with the recto, but I'm really happy about the result!!
Well I certainly don't buy into the myth, hence why I own a TS7, but honestly, none of the things you've described as being characteristic of the SD-1 appeal to me personally! (especially the lesser amount of bass cut, cuz that is...ahem...QUITE necessary with the amp in question here)
