Serpentine comment: I demo'd the VTM 200's as well as the Ref 300 MKII, and purchased the latter. These were replaced by the Tenor OTL's which were better to me. After 2 years with the Tenors, I moved to the Tenor 300 Hybrids, which I thought bettered the OTL's. About a year ago I demo'd the DarTZeel and A/B'd it in house against the 300's, sold the latter and purchased the former. Ergo, unless the Verity's are a herculean load from hell, which I happen to know they are not, to me the DarTZeel would be the unequivical choice. It is the best sounding amp I've had in my system, and although system matching always needs to be considered, I can recommend the DarTZeel without hesitation. It is music.
