The best speaker you ever heard?

I have listened extensively to the new Auditorium-23 Cinema Hommage speakers. They are absolutely stunning in every way. Musical presence, soundstaging, instrument textures, timbral accuracy, transparency, dynamics, resolution, weight - everything I could ever hope for in music reproduction, rendered in a way and to a degree that I have never before experienced. It might take weeks or even months, but I am going to find a way to own a pair!

I will go arc/sonus faber combination. I have ref3 if I go smaller I will get vsi60 arc integrated with sonus faber speaker.

The two that have stuck with me – each for a completely different reason - were the Volti Vittora and the Goldmund Prologos.

+ 1. The Prologos are very dynamic and musical speakers. They sound very smooth and are good sound stagers. I would love to hear the mighty Apologue Anniversary!

the 80k Rockports are pretty amazing too. Forget the name, but I've heard them really sing with some incredible amplification and vinyl.

in my own personal experience I have to say Advent 6003 speakers are best I have had. I bought a pair new in 1985 or 86. I first took home a pair of the large, 2 way Advents with the fried egg tweeter. my wife insisted on the 3 way speakers. we returned the 2 way speakers, and got the 6003s. never have regretted that. still have those. we had listened to a lot of speakers and for $650 for the pair new we thought those were a great buy. I sell Jolida audio gear. Have had quite a few Klipsch vintage speakers come through our store. The 6003s sound a good bit better than the Fortes, a bit better than the Cornwalls, and the 6003s put the RF52II and RF62II speakers to bed handily. No comparison there. Connected to the JD502CRC tube amp and using the FX DACIII jazz sounds live right there in the store. Norah Jones sounds so nice. There is not much information on these speakers. Made about 85 and 86. 3 way speakers, 10" woofer that does put out some bass. These are hard to find speakers, and rare to find in really good condition. If you ever have a chance to get a pair do so. With the right amp these are capable of being real exciting to listen to. And very real to life sounding. In my own opinion. In the old days Advent represented real value for an accurate sounding speaker.
