" This, coupled with a balanced, spacious, and easy-to-listen-to sound signature, make the SV023 a great choice for budget-oriented, style-conscious audiophiles.

OTL amp owners should put the SV023 on their shortlist, as there are few high-impedance options beyond Beyerdynamic, Sennheiser, and ZMF. The SV023 slot in nicely, priced slightly above the German options, and bring a taste of the luxury offered by the high-end ZMF models."
