How many hours do you have on your Achilles / Alexander?
Have no doubts you've been working very hard to get so many new RALR items past the initial stages. If you already started listening to Classical. This indoor listening season is going to be incomparable.
Can I ask for a stylistic description of music you are currently finding exemplifies equipment in house. Obviously better sound is yet to come if you are just now getting some expressions of energy welling up.
I can't put a number on the hours, only that I think I have just recently crossed the "burned in" threshold. I was told the sound changes quite a bit after a couple hundred hours—and there were the typical good and bad days along the way. But, as Pilium is SS I didn't need to worry about using up tube hours, so was comfortable using Roon Radio and playing for good long stretches then shutting things down for a few hours and starting again. That said, things improved more when I started "exercising" the system with music at 70-90db levels. If anything, the Alsyvox Botticelli external crossover is probably still the piece of kit that can benefit from more hours.
The Pilium kit is remarkable—it will compete with any of the top level kit, excelling in a liquid delivery that completely gets out of the way. Detail with delicacy and nuance, without a hint of harshness anywhere.
My wife has invited her office team over this afternoon for a social gathering. She's very, very fond of Botticelli X, so those are moving into position shortly. They'll stay until at least next week as I have a visitor interested in hearing them.
I'm unsure of your question re: "stylistic description" so I'll just say I am primarily a jazz, blues, and funk kinda guy. Pop-rock, classic rock too. Melody Gardot to Van Morrison, with Daft Punk, Yello, etc. Classical—I can enjoy it so long as it is melodic (same for jazz) and dynamic. Otherwise, to me, classical is one of the best sleeping pills I know of. Chamber music... I'd rather eat broken glass (with some exceptions).
Every night I have a very big smile on my face. I never imagined having such top level kit to enjoy, it is so much fun!
