Colleagues, does anybody known which tube amps (both power and integrated) have very low distortion and measure well in general? I am aware of only two : McIntosh MC275 and Quad II Classic Integrated.

I am sure that there are more out there. Could someone please let me know of other low distortion tube amps.

Many thanks.

Audio Research has several tube amplifiers that are currently in production, and has made many other model over the years that are available used. Virtually all of them have extremely low distortion. Many experts consider them to be the very best ones that are currently available.

The Audio Research Reference 75SE and Reference 150SE will possibly be of great interest to you.

Primaluna is another company that builds excellent tube power amplifiers.

BAT is another one.

Many many high-quality tube amplifiers have been reviewed by Stereophile over the years, and those reviews can be found here on this website.

I suggest that you look at the Audio Research website for the current models, and that you also look at the ARCDB website, which is a database of every Audio Research product ever made, including current ones, with complete specs and pictures.

You might also want to call Upscale Audio at 909-931-9686 and talk to them about what is available. They carry Primaluna and other high quality tube amplifiers.

The Audio Research Vsi75 Integrated Amplifier is another excellent product, and the Primaluna Dialogue Premium HP is another.

I would second contacting Kevin at Upscal Audio. I bought my DAC from him and he helped guide me in making a preamp choice. Very knowledgeable
