Peterayer, please bear with me with some background before I get to answering your questions, I feel that its an important part of this conversation.
Nothing is perfect and judging any piece of equipment is always in the context of a system that has many variables including the stands, quality of mains and listening space. I know that I haven't addressed all the issues in my music chain so everything in that context. What I have done is move around a lot and tried enough different components in my own systems or those of my clients and friends to know what my music chain is or isn't doing right. My own two main systems have remained more or less the same for the past 10+ years so I'm very familiar with it. So always keep this in mind when people comment on equipment. its never in isolation. But there are certain characteristics that one can pick up if they know what to look for.
I have my standard reference arm/cartridge combination and almost the tables I refer to always have this arm/cartridge combination set up as standard. Unless provided by manufacturer, they all sit on massive vibraplane type lab tables but I don't use air with any of them.
The reference tables mentioned in my threads all perform at exceptionally high levels and don't sonically suffer in any obvious way, I really can't find any weaknesses in them. They don't have what a lot of people call vinyl sound. There's no thickness or ripeness like a Linn nor is it thin hyper detail sound ala Clearaudio, they're very neutral and balanced. Many listeners have expectation of overt character when it comes to lps and are initially thrown off by the neutrality of these players and even more surprising is the actual lp that has no "vinyl sound" like we always thought was there growing up with mass market systems. It takes them some time to get beyond that expectation. This is apart from the analogue vs digital conversation.
To your questions on the EMT 927, I don't hear any shortcomings that I can't attribute to other parts of my system. They're there with every source that I listen to including digital. I love the ergonomics of this table, its just joy to set up and use. For me 927's most unique sonic quality is what I mentioned above. Its the solidity with density and the way it brings forward the space and ambience of the recording. I'm not a reviewer and apologize for not having the vocabulary to express this in audiophile terminology. its not about bass, mids, highs, etc., or anything in isolation, its the total presentation that is very natural and real. That's the best compliment I can give any product. The American Sound has many of the same qualities and perhaps slightly more detailed sound.
Obviously I've only listened to a fraction of what's out there under controlled conditions. Mostly its been the mega buck unobtaniums that I have experience with. On the sane price level I like TW acoustics tables, very little to complain about, they sound excellent and considering the ridiculousness of high end audio these days are relatively good value . Given the availability of 301/401 Garrards and companies like Loricraft or Artisan Fidelity who refurbish and supply very good plinths, they can be considered current production and I highly recommend them. Again, aside from the excellent sound quality they offer value in today's market. I can recommend Loricraft's 501 as an excellent modern day idler, haven't heard Mosin's beauty but its on my radar and to try list. At the stupidly expensive end, I like the Vinci and of course the AirForce One, the upcoming, less expensive AirForce Two should be interesting too. Disclaimer, as a dealer I have vested interest in the AirForce tables.
