I have just acquired one of these amazing valve amps and been using in conjunction with a pair of 1966 Goodmans eleganzia 2's speakers which are rated at 16 ohms. The results are truly breathtaking. The warm sound added with superb bass control and superb dynamics can only be described as amazing. very highly recommended.
