Have owned Classic 30s (a pair used to vertically bi-amp) on ML Arias and Dunlavy SC4s, and currently own a pair of Clssic 150s. I have played with a '60 while making the decision to go whole hog and grab the 150's many years back. I've been running the 150's very happily ever since into Merlin VSMs. The entire Classic series are brilliant amplifiers, particularly when you dial in the sound with some good NOS tubes. They respond particularly well to ARC's newer linestages. Oh, and one last thought. There are a handful of MIT coupling capacitors in the circuit which a capable tech can replace with Hovlands that along with the afore-mentioned NOS tubes, really eliminates any tendencies toward "glare" at high outputs that some Classic users have noted. Highly recommended!
