I have to say that Porcupine Tree - In Absentia; tracks like Trains sound very good indeed.
Their later albums in my opinion haven't been mixed as well. I may be wrong
This is exactly what is great about progressive rock and progressive metal. Most of it is recorded well, some of it very well. Progressive artists actually seem to care how their music sounds which is great for us audiophiles. I don't have to cringe listening to most of my favorites with resolving headphones like the Q701, and the GR01.
Porcupine Tree is recorded well, most of Opeth's stuff is recorded well too, it seems most of the little known bands (non-mainstream) seem to really care about production. Threshold's new album is good, both of Haken's albums are good, Headspace, Oddland, To-mera, Frequency Drift, Chimp Spanner, Andromeda, Riverside, Arch/Matheos, and OSI are all bands that have good production on their music. I'm listening to Oddland right now, and the clarity is great, especially the vocal mix.
I've really been enjoying the way the new High On Fire album sounds. De Vermis Mysteriis. I usually find listening to metal on headphones to be a depressing experience--headphones are good for lots of things, but not metal, I've always felt. This is one of the albums that proves me wrong.
Right. That said, I actually think the production on the new High on Fire album is quite good. The first time the drums kick into the mix (which is to say, as soon as you push play) they actually sound like drums, which thrills me to no end.
as for me here is one of the best (not in order):
Yngwie Malmsteen - concerto suite for electric guitar and orchestra in b minor op. 1 and millennium Concerto suite
an Evening with Jordan Rudess and John Petrucci
Eagles Hell Freezes over - DTS audio CD
The Classical Conspiracy and Score: An Epic Journey by Epica
any other idea please share here.
Krallice - Years Past Matter

For progressive rock, Glass Hammer's Culture of Ascent is an amazing sounding album. There is a lot of complexity, and the production is top notch... I find something new almost every time I listen. Unfortunately, I made the mistake of downloading it off itunes. I wish I had it in lossless.
Wintersun - TIME I
The musical interludes and power of the instrumentals seems like it would only get better with equipment.
EDIT: On a related note, Wintersun is one of the best live metal bands I've seen in a long time!
