nCore is getting some good reviews. And there are a bunch of ICE-powered designs that are gaining traction. It is a *very* good time for high-quality, real-world pricing on all sorts of gear...
If everybody knew those brands the high end would not be the dieing old man's game that it is today.
That said, D'agostino, Continuum, Allnic. Funny that you don't mention any tube gear since good soundstaging seems to be the calling card of tube electronics.
Halcro appears to be out of business or dormant.
"What are the new brands which also can give a very musical sound and a holographic 3d image?"
I'm not so sure its a good idea to go about looking for equipment just by picking "new" companies. I think that there's something to be said for a company that is successful enough to become an old. also, old companies make new models.
I'll meet you half way. Based on the sonic qualities asked for in the above quote, I recommend a middle aged company. Ayre.
My vote for new brand would Mystere. I have a Mystere CA11 tube preamp. Couldn't be happier. I traded in my Primaluna preamp for the Mystere. Very nice tube preamp. I highly recommend Mystere to those individuals looking for quality sound, robust build, and affordability. The warranty is also above industry standard in the price class.
Stereophile is doing a decent job of covering CES and you can read a little about several new companies, as well as several old companies that have resurfaced with different names...like Edge. I don't recall the new name for the guys that developed the Edge gear, but they have lowered their prices a lot, yet still pack them full of audio quality.
I know this thread is old now, but I want to second the vote for Wells Audio. I tried the Innamorata amplifier in my home and compared it directly against two conrad johnson amps and a Marantz amp. All three were at one time or another highly recommended by Stereophile etc. The Wells was substantially better. More micro detail, quieter, more dynamics, better bass yet smooth highs. I was sold. I bought two and use them in a veritcal biamp set up. At $6k retail, I think this amp is fantastic.
They are not really new, have been around for many years but are still relatively unknown is Bakoon Products. Amazing sounding solid state amps that are quite beguiling. They sound so right. The little 15 watt integrated drives my Tannoys really well but also my Gale 401a's very nicely, to relatively moderate levels.
Not sure where to draw the line between new and old, so I just list the ones I have heard that do that particularly well.
Audio Research, Bel Canto, mhdt, Dynaudio, Triangle, OHM, mbl, Magico, DCS, PSB, Daedalus, Rockport, Totem, Tidal, Cathedral, Classic Audio Reproductions, Atmasphere, Nola, Magnepan, Rogue, Vandersteen, Goldenear, Krell, Classe, Martin Logan.
These are the ones I have heard that stood out. SO many other good ones.....setup and synergy is always a key.
The Pass Int30A would be a better match for the Pl-200. But....for the Pl-300 the A32 will be a much better advice. Why? Very simple, it gives you much more control and drive. This is the funpart of the Pl-300. Don't forget that the Pl-200 3 years later came on the market. Exept the drive the Pl-200 is far superior over the Pl-300. I sold mine and many of my clients their Pl-300. They now play with Pl-200 and a subwoofer. This outperforms the Pl-300 with a subwoofer with ease!
