@keithr, Since you are coming from a Music First Audio TVC preamp, you will value a preamp that's not colored or voiced I guess. Shindo, Audio Note, CJ and the likes are all very voiced products. They have a strong house sound.
At least I have used them all and found it that way. If you want a really good preamp without voicing and full range, direct sound, check out Wavac PR-Z1 or PRT-1. Fast, natural, glowing sound without voicing.
