Pairing Yamamoto A-O8S amp with Supratek Cortese

I am running an Edgarhorn Titan ll system with Seismic Sub. The system is rated at 107DB into 8ohm load throughout. I have both a Yamamoto A08S and Korneff 45 and the 2 WPC will idle into these speakers. These two 45 amp.s are both in the top category of 45's and each offer a different perspective with the 45 tube. The Yamamoto with NOS RCA GLOBE is more lit up in the midrange and the Korneff is focused on tonal hues and richness with a more powerful bass on these speakers. Your mileage will vary depending on the speakers but I think 45's have a limit of speakers that are not much less than 98DB into 8ohm load in a small to average size room. One thing for sure is that if you mate one of these amps. to the right speakers it will walk the dog but once the efficiency point is reached your out of gas quickly.

I am using a Korneff 45 with upgraded Klipsch K-Horns, the only thing original are the cabinets and the 15in woofer. The mids horns are Volti Audio and have a 2in throat matched to a BMS 2in Driver rated @118db, and an upgraded tweeter. This is by far the sweetest combo I have heard in my setup.

Volti Audio truly understands Horn Loudspeakers, and All Horn Loudspeakers like their Vittora. I have heard these extensively and I have never heard a cello, upright bass and just bass in general sound so palpable in a room than with the Volti Audio Vittoras.
