Milimetr,
I enjoyed your digression. I have owned my BN since it came out. The Raven Anniversary is gorgeous and I would myself have gone that way just due to the ergonomics.
The battery PSU is a huge improvement. I have compared them side by side in my system. And the BN difference to the original AC is as you described.
Schroder is a piece of work. He comes from the watch industry which I know professionally. Quite a few brands limit production to create demand. Yes it is manual labor, yes it takes time. But Tonearms for $10K and where is the gold?
The problem is the Schroder Lyra match is something special. I own it now for years. You can see tons of posts by me here. I also have heard several setups with Lyras on Scroder arms and always have been impressed. I stopped changing arms before the latest round of wood arm copy cats came out. They might be good. The other idea which might be great is the Kuzma , Atlas combination. Lyra puts out a lot of energy and needs an arm that can handle it. And the Schroder is very difficult to set up. And, I am being nice in saying that, as very is based on years of experience.
I have never tried the Atlas or Allnic. But I owned a few Koetsus, Benz, Air Tight, VdH, Dynavector, and more. I just don't find a need to compare, when I find nothing lacking in my front end. If I had just 1 cartridge arm combination, then I probably would get back to searching. it is just that different music sounds different depending on the cartridge/arm used. not necessarily better, but more to the mood I am in.
I would never buy a cartridge from someone who rebrands it unless absolutely unique.
Lyra, Ortofon, Koetsu (but they are too delicate for the amount of money) and Dynavector are not equipment manufacturers first. They are primarily in the cartridge business. Some of the boutique brands are excellent as well as that is all they do. I just wouldn't buy a watch made by Porsche. Even though it might be excellent. I would much rather get a Breitling since that is what they do. But, I would consider some of the more limited production watches such as A. Lange etc.
