What s the best Class A integrated tube amp over 80W


I am using Sound Lab ESL speakers, which have a very high impedance at low frequency (30 ohms). At high frequency, SL speakers have very low impedance (3 ohms). I loved the class A in Pass Labs amp, but it took too long to FULLY warm up in my small room (9x11)-5-6 hours. I have a thread on Agon on this topic, but now I would like some recommendations on the best Class A tube integrated amp with >80W. Usually, integrated are the budget model of the line, but must be GREAT class A tube integrateds. Any recommendations?

i agree the primaluna’s sound good and are an excellent value for performance and features... but i would not say they are with quite with the top tier of tube amps such as audio research and vac
"Primaluna Dialogue Premium HP 75w using EL34’s or higher wattage with KT88, KT120, or KT150."

The PLHP is a class A/B as some of the others mentioned. I have the PLHP. Good stuff for the money. Perhaps like most decent amps the PL HP's first few watt(s) or so is "class A"? Just a  guess.


An amplifier operating at true "class A" producing 80 WATTS would be as big as a car and produce massive heat. No one would be able to stay in the room. If they did, they would be deaf!

I’m two months in with a new Rogue Audio Cronus Magnum III. It is 100 wpc integrated that can switch from linear to triode mode, is built in the US and is a terrific value. Nice on board phono stage (the MoFi Ultradeck sounds fabulous through it) and a separate headphone circuit too. Runs not too warm which matters in a room your size. My Line Magnetic 508ia cooks me in the summer although I admit it is a better sounding amp all around. The Rogue is well built and has a flat, clean, industrial, exposed tube look. I am paired with easy to drive Klipsch Heresy IVs so I can’t speak to how it will handle the ESLs.
Leave you Pass Lab amps ON. I have heard of a sound studio left theirs on for over 20 years without a failure of any kind. You may find a nice integrated amp but will probably not sound as good as Pass equipment.
please give the Rogers High Fidelity EHF-100 or EHF-200 tube integrated amplifier some thought.
a definite plus is that Roger G. (in MA) always answers the phone and is extremely helpful without being overly pushy.
