Eidolon vs Opus

I find Jtinn's strong comments on the Kharma vs. Eidolon a bit perplexing. Eidolons with fast and resolute electronics, like Spectral and the top ARC amps, is as coherent, transparent, and resolute as I have heard, very close to electrostatics in many ways. I have heard the Kharma Exquisite and Lamm combination only at shows, and it was clear that the Kharmas are excellent speakers with fuller, more fleshed out bass than Eidolons; however they were probably imaging the bloom provided by the Lamm tubed electronics. Eidolons will also image bloom from tubes, as was evident in Harley's many comments on the ARC/Eidolon combination.
In the end, you should listen to both Eidolons and Kharmas (which Kharmas?) with your own choice of electronics. I can't imagine being disappointed with the Eidolons, which have been widely praised for the same characteristics that Jtinn mentions.

Flex: I am not dismissing how good the Avalon speakers are, I am very familiar with them and they are quite good.

I have heard the Avalon's with Spectral, ARC, Ayre, Atma-sphere, and many others and my conclusions were always the same. Personally I thought the best combo I heard was with OTL's.

The Kharma's are just amazing. The Avalon speakers do tend to be on the thin side and do not integrate the bass and midrange as well as the Kharma speakers. As good as the imaging and staging is with the Avalon's, the Kharma's take it up a few notches.

The Kharma / LAMM synergy is quite good, however when matched with the Tenor amplifiers, they are the most lifelike speaker I have ever heard.

MES had the combination of Eidilon's and ARC Ref 300 MK II's. He hated his experience with them. He found the lower midrange to be very bloaty.

As a reminder, I am a dealer for Kharma and not for Avalon. If I liked the Avalon speakers enough, I would carry them.

Jtinn, nice follow-up. Thanks for the additional clarification and for reminding everyone that you are a Kharma dealer. I must admit that I don't hear the mid-bass bloat you say MES complained of with the Eidolon and ARC Ref 300 MK II's. I run my Eidolon's with Atma-Sphere MA-2 MkII's and find the integration to be outstandlingly good. Given what I hear with the Eidolon/Atma-Sphere combination, the Kharma truly must be outstanding.

BTW, you never did clarify which model of the Kharma you're referring to.

After reading this post I think everyone can see that what works for one person doesn't work for another. Go listen for yourself and go with what you like best. If someone buys Kharma and another buys Avalon they both will have great speakers to them. To others they will not like those speakers for one reason or another. What I find funny is today its Kharma, next week its Avalon, the week after that its something else. I always like reading old post where one person will say something is the best they have ever heard until they hear something else. I have been very lucky (I think) to have owned many speakers and all have their strengths and weekness. One of the best systems I have every heard was with Avalon Radians. Now does that make Avalons the best, no but they where nice.

This is starting to sound like the person who buys a BMW just to hear another person say they use to like BMW but now Mercedes are the best. They all are very fine and I would love to own either.

Ha, Ha, Ha -- well said, Bryans! And in the meantime we've lost any additional replies to Rmaurin's original question about what to expect if he upgrades from Opus to Eidolon.
