Should I replace my 20-year-old Hovland Radia Amp?


I recently upgraded my speakers to Sonus Faber Olympica Nova V. My preamp is a relatively new Pass XP-30. Ditto my VPI Prime Signature turntable and Moon 280 D streamer. My phono preamp is an older ARC PH-7. 

About 20 years ago a friend asked me to help him buy a new system. We took three days and drove all over Southern California. He purchased Wilson Sophia speakers. The dealer recommended the Hovland Radia amp. The Radia was the only solid state amp Hovland ever made. The company cliams it took ten years to perfect it. We tested the Radia against a few other very good amps and both liked it. Several years ago my friend passed away and I inherited the Radia.

Paul Bolin describes the attributes of the amp in a 2004 review much better than I could : "[The] Radia was a delight to listen to in virtually all respects. It consistently displayed a light, limber touch with images and timbres. Dimensionality was surprisingly and delightfully tubelike in its solidity and freedom from too-sharp, unnatural-sounding ultra-definition. The point source of each instrument's body was clearly discernible, but didn't exist in highlighted isolation from the air around it or the sound of the recording venue. The Hovland's overall resolution of detail was very good, bordering on the truly exceptional, and there was never any sense of resolution for its own sake. It always maintained a holistic sense of continuity, embracing all aspects of the music and knitting together the disparate parts of the recorded experience."

I was fifty-eight when I took that three-day jaunt with my friend who purchased a fairly expensive stereo system. I am now 78 and do not have the energy to go looking all over L.A. for a new amp. I could, however, go to a few dealers. The one closest to me carries Macintosh amps. 

My question is this: could the superb Hovland Radia now be so out-of-date that I should seriously think about replacing it? Or just "love the one I'm with"?

I was going to keep the Hovland Radia until it died or I could hear its sound being diminished by age. Then I found out that I could have Bob Hovland, the designer and manufacturer of the Hovland Radia, check it over and bring it up to spec. I couldn't pass up that chance, so its with its father for an overhaul.

I have a Linn LK 140 on loan. It's not terrible (except for the first few brittle hours), but I know why I love the Hovland. The Linn sounds as though the soundstage has been compressed. But in that compression everything else is compressed. Cymbals don't really decay. They more thud to a conclusion. Drums have a strong attack which I'm sure would please many listeners. "Great bass!" Except on the Hovland I heard the last vibrations which are missing with the Linn. It is as if the Linn is a rose bud and the Hovland Radia is a rose in its prime with all its glorious colors showing.

Finding subjectively ideal sonics within budget can be daunting, sticking with the Sonics you like in your amp is a solid choice.

I have the person who designed and tuned the amp evaluating it. The sparkling reviews I read of it when it was new described attributes I like. I'm thinking if Hovland works on it, the amp will only get better. At least, that's the bet I'm making. Hovland made all tube amps until the Radia which has all the good attributes of tubes while adding deeper bass and sharper attacks of solid state. I will let you know.

Bob Hovland the designer and builder of the Hovland Radia tested the amp to bring it up to specs. He said after twenty years everything was up to specs. Apparently he built the amp with high-grade industrial parts that don't wear out too easily. He set the biases and soldered a few wires that weren't tight. The amp is as good as new. It is an amazing sounding amp. That was confirmed when I borrowed a Linn LK 140 to use while the Radia was being tested. The Linn's soundstage shrunk as did the music and the air between instruments. The Hovland Radia is in a different league. My guess is it would be difficult to find its equal in its original price range of $10,000. I think it would hold its own with other very expensive stereo amps that are in the 100 + watt range.
