Why dont more standalone DACs come with ethernet???
There are definitely getting to be more available. Bel Canto e1X and Black EX DACs both have Ethernet input. Disclosure: we're a Canadian Bel Canto dealer.Gold Note is another and there are more as well. But, still not very common at all. 
Hegel H390 vs Krell Vanguard digital integrates amps
There was a review by HifiCritic pitting the H390 against the Krell K-300i and the Mark Levinson 5805. Both are much more expensive than the Hegel, but in the review the Hegel easily came out on top. Disclosure: we're a Canadian Hegel dealer and I... 
Phono preamp worth it with MM cartridges?
A good phono preamp will definitely be worthwhile for MM cartridges as well. The best we've heard in the under $2K price point is the Vertere PHONO-1 MkII.

We subscribe to a top-down philosophy, so typically higher in the signal path provides more improvement. In this scenario, I'd go for the better cable from your source to preamp.  
Best debut album
Tord Gustavsen Trio - Changing PlacesEven though it wasn't that long ago in 2003, it inspired a lot of incredible Norwegian jazz that followed it.Tracy Chapman - self titled album. Not just "Fast Car", but a great album across the board.

Bel Canto products have always worked well with Logitech Harmony remotes. 
Salk bookshelf or Dynaudio bookshelf? Or something else?
Thanks for the extra information. Unfortunately, I'm not up on vintage speakers, so I'm unable to offer an opinion on either of those speakers. 
Salk bookshelf or Dynaudio bookshelf? Or something else?

Floor protection from spikes
For a very reasonable price, we really like Soundcare Superspikes. They're a threaded spike with self contained footer. A really durable felt goes underneath the footer which makes it very easy to slide and reposition your speakers while keeping y... 
Bel Canto ref500 question
The REF500M monos are a step up from the REF500S stereo amp, but it has been a long time since I've compared the two that I can't fully recall the differences.  
Bel Canto ref500 question
Currently, they are only building the REF500S stereo amp. The REF500M have been discontinued for quite a while already. The more recent REF600M are quite a step up from the former REF500M.  
Moon by Simaudio, Arcam and Hegel: Quality of Customer and Technical Phone Support
Sound quality and value for the money with the Hegel integrated amps is exceptional. However, feel free to take this with a grain of salt if you like as I'm a Hegel dealer in Canada. Depending on your speakers, the Hegel H120 could be a great fit.... 
Moon by Simaudio, Arcam and Hegel: Quality of Customer and Technical Phone Support
Absolutely agree with cleeds. These are services to be provided by the dealer, not the manufacturer.  
Hegel H190 Universal Remote
Most universal remotes typically have a learning function as well. If not, the Hegel codes are quite common with some other brands. I was able to control a Simaudio integrated amp with the RC8 before, so you could try Simaudio codes if listed for ... 
Bel Canto 3.0 vs 2.7 DACs
I haven't done a side by side, but their latest DAC2.7 is supposed to eclipse their previous DAC3.7 which came with the VBL1.
