I'm not sure what motivated me to read the owner's manual for the Audio Valve Eclipse, but I'm glad I did: As it turns out, this line-level preamplifier has at least one distinctive feature that I would have missed otherwise.
First, a few basics: Audio Valve was founded by Helmut Becker, a German guitarist and music enthusiast who began building amplifiers 40 years ago, at age 15, and who has spent the greater portion of his professional life building audio electronics and medical equipment. Herr Becker and his wife, Heike, operate Audio Valve in Kalletal, a municipality in the Lippe…

Sidebar 3: Measurements
I performed all my measurements using the CD1 input. I didn't measure the Audio Valve Eclipse from its XLR jacks, however. As explained in the manual, these are not true balanced outputs; instead, they are unbalanced, paralleling the output on the RCA jacks on pin 2, with pin 3 connected to ground. The preamplifier's maximum voltage gain from the CD1 input was a modest 7.15dB, with the unity-gain setting of the volume control at 4:00. The gains from the other inputs ranged from 5.15dB, CD2 to 15.9dB, tuner and tape. It looks as if the different input sensitivities…
Robert J. Reina wrote about the Audio Valve Eclipse preamplifier in June 2008 (Vol.31 No.6):
I was excited when I heard that Art Dudley was going to review the Eclipse line preamplifier from German manufacturer Audio Valve (Stereophile, August 2007). I have owned the preamp for four years now and have enjoyed every minute of it. But I wondered what Art might say about it. To my ears, the Eclipse was detailed and dynamic, but had no sound of its own—no coloration, no sonic signature. How could AD stretch that into an entire review and make it informative and entertaining? I then thought…

When I attend Stereophile's annual Home Entertainment show, I rarely sit and listen to music for very long. Instead, I try to hit every room, press the flesh, find out about new products, and play a little jazz.
But HE2006, in Los Angeles, was different. I must have spent three hours listening critically to the wonderful music and sound I heard in the three rooms occupied by the Audio Research Corporation, who'd hooked up their Reference line of electronics to speakers from Thiel, Vandersteen, and Wilson. The ARC gear included the Reference CD7 CD player, the Reference 3 line-…
The second of the 110's remarkable strengths was its ability to render high frequencies with a clean, pristine, extended presentation totally devoid of electronic artifacts. This was also my reaction to the high frequencies of ARC's Reference 3 line-stage preamplifier (see my Follow-Up in the June issue, p.139); in this region, clearly, these two designs were cut from the same sonic cloth. I tested the Reference 110 with both the Reference 3 and Audio Valve Eklipse's line stage, and the amp's high-frequency strengths shone through both (although the effect was notably greater with the ARC…
