only source material that one can play on this to hear the inherent advantages of great analog playback is limited to LPs from the Golden Age (~58-80).
This could be debated (tongue in cheek). But, when Doug Sax died, "..Acoustic Sounds’ CEO Chad Kassem has purchased The Mastering Lab (TML) from the estate of legendary mastering engineer Doug Sax." http://news.acousticsounds.com/post.cfm/acoustic-sounds-buys-legendary-vinyl-mastering-facility. So, Chad has the complete tube mixing panel that Doug Sax developed.
Also, some of the re-pressing of the older music such as https://store.acousticsounds.com/d/...n-This_Ones_For_Blanton-180_Gram_Vinyl_Record, are really very good, and in this particular case not terribly expensive.
Bernie Grundman can mix with a tube console, and keep it analog to the end, it's up to the customer. https://www.berniegrundmanmastering.com/equipment-technology.html.
Kevin Gary can mix/cut completely in analog, again, it's up to the customer - https://www.cohearent.com/our-system/.
Additionally, there has been quite a bit of work at bettering the vinyl composition that can challenge the benchmarks of say the legendary (and mysterious) JVC compound. So, there are examples of record being pressed today that can challenge the best of years past.
Curious enough, this new Solution 787 Turntable is not very big (~19"W x 18"D x 10"H) and it's not very heavy 36-kg (79-lbs). In comparison to many uber tables, it's downright svelte. So, interesting to see the roll-out and reviews and the price and see the community's overall reaction.
