We are now have stock of the
Graham Slee Novo headphone amp. Initial listening tests are very impressive.
While the amp doesn't look much, it drives high impedance headphones like the Sennheiser HD650 or AKG K701 with real authority. Exhibiting the signature Graham Slee delivery of very open mids and highs, with plenty of low end punch, I like this amp a lot.
The
Graham Slee Solo has long been the benchmark headphone amplifier for listening tests here at HiFi Headphones. The Novo looks set to give the Solo a run for it's money, even with it's significantly cheaper price tag.
