The Reference 75 ($9000) is similar to the Ref 110 and Ref 150 in that all three use input circuits using direct-coupled JFETs and a 6H30 tube. However, the Ref 75 has only four Tungsol KT120 output tubes (in ARC's ultralinear "partially cathode coupled" topology), compared with eight in the Ref 150, and eight 6550Cs in the Ref 110.

The Audio Research Reference 75 is the baby power amplifier of the company's top range and is intended for those who want top-quality sound but don’t need any extra power. (Those that do need the oomph can have the likes of the range-topping Reference 750 monoblocs, which output a spicy 750W and sell for an equally spicy rather hefty £27,500 each.)

Holding my hands over my ears, I ran back into the room to check how far into clipping the meters were registering on the peaks—their scale far exceeds the Ref 75's claimed output of 75Wpc. "45W," they said. Comparisons I compared the Reference 75 with my Reference 110 ($9995 when last offered), which has the stock 6550C output tubes. (Although all current ARC power …

Audio Research Reference 75SE stereo power amplifier. Sircom’s First Law of Amplification states that the thermal output of any amplifier under test is directly proportional to the ambient temperature of the environment.

Firing up the Audio Research REF 75SE for the first time, the amplifier is pleasant, but not OMG. However, like all ARC products, the REF 75SE needs some time on the clock to give it’s all. ARC suggests 600 hours of playing time, and while past REF components required close to this, even after the 50 and 100-hour mark has passed, the magic happens in earnest.

Audio Research 75 SE. I just heard there is an Audio Research Ref 5 SE and they are offering the update to Ref 75 owners.

Anybody heard it.
