I met Ralph when I lived in Mpls,Mn after his first amps were coming out;I think his amps are one of the best in the world if your speakers are able to be driven by a OTL amplifier;having said that when I heard his amps they
were driving a soundlab speaker and the sound was first rate;controlled bass, midrange a tube lover dies for, and the highs were very exteneded; just fantastic.If your speakers are not OTL compatable Ralph suggests Paul Speltz's autoformer to increase the speaker impedance and make it a better load for the amp(s).
I think if there is any questions on that situation it is best to converse directly with Ralph;he will always give you a straight answer and not jam his gear down your throat to make a sale.
