    Only at shows and my reaction has run from awful to lukewarm to interesting. But the Class D amps all seem to have the same characteristics. Flat, kind of unfocussed and loss of information.
    My finding so far is the same.

The Kaluga, much like the Q5, is resolved and uncolored - you hear what's in the recording. Not for everyone's taste, to be sure, but works very well for me.

      I really don't want to get on an amplifier merry-go-round. Perhaps there's something better, but I'm trying, for once, to be content with something that works quite well.

      Come listen if you'd like!
      Constellation amp is pretty good.

        I heard the Kaluga monos with the Makua line/phono stage, on our YGs and Evolutions. While they *do* have traits of the Class D sound, they're considerably less offensive than Class Ds of years past.

        The better deal of the two was the Makua preamp. You can get the preamp+phonostage+DAC for roughly $20k, and the cool thing is that *all* the 6 inputs can be used for phono!

        Now, if you want something impressive, check out the Kii Three speakers, from the same developer/manufacturer...

          Alex great meeting you at Newport. What are the traits of Class D amps?

        Do you mean it has 6 effective internal phono stages or it has 6 line stages for external phono stages?

          Only problem was the volume control squeaked everytime the remote was used at Axpona.

            One question I have is do Class D amplifiers have difficulty driving difficult loads eg. Mike's Thiel 7.2s.

              I have not found many solid state amps that do not sound bright on my Thiels. The Pass X-350 was one exception. And I think the Maggies are a fairly difficult load but the Gilmore Raptors drove them ok. Again amp - speaker matching is really important.

            No, it has one phono stage, and 6 inputs, and you can route any one of the 6 inputs to the internal phono stage. You can also have "virtual" inputs, so you can have a virtual input set for each one of your cartridges, with their optimal settings. That way, you can switch inputs, but the turntable is still connected to the same physical jack in the back, and only the settings change.

            Pretty neat, if you ask me

              Ah, I see, it has one very good phono stage with six phono inputs to that stage.

                This seems to be a good spot for Myles' impressions of the Merrill Veritas. (Subtle, ain't I?)

                  It has its own thread already right?

                    I have a NuPrime ST-10, upgraded by TDSS in Valparaiso, and especially for what I paid, I'm very happy. Running Dynaudio Focus 260 speakers. I honestly don't get "dry" out of these but I also wouldn't necessarily say they are warm by any means either. It strikes me as neutral, revealing, and quiet, from a noise floor perspective. Being that I listen to a lot of music with copious amounts of "drive" in it - wailing guitars, quick tempo drumming - the ST-10 has been a workhorse for me. That said? I am contemplating a move to a McCormack amp if/when I can find a decent deal on an already upgraded one. I actually worry that a McCormack might be a little too "smooth" for the music I listen to (hard rock, metal, prog) most. I want a little edge, a little bit of a visceral feel if that makes sense. The only other amp I have to compare to is an Odysssey Stratos, upgraded by Klaus. It's close, but for me the upgraded ST-10 is my preference. As for soundstaging, my room is small so I can only expect so much but I get a wide image and enough depth to keep me happy.
