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?

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.
Hello Chungjh, if I were to tell you, you probably wouldn’t believe me or it.  I’m assuming because I didn’t, but learned the hard way. Spent a ton of money and got me almost there: But not to where my system was perfect.  Now I currently have 3 setups where they sound perfect to me.   What am I talking about?   Older items.  People, including myself discounted older items because in my belief, there couldn’t  be any way something older could sound better than something new-  I needed to learn.  I’ve listened to a lot of “state of the art” current products and many of them fall way short of some of the classic designs.  I have many great tube amps to recommend that are a little old but are truly killer. Do you want my advice? Been in this hobby for 30 yrs.   I’ll just leave you with 2 different sounding amps but extremely fine items. Conrad Johnson Premier Four (100 watts)
