I have 6 days on my Lampi now. It is just nuts. First, I am one of those guys that don't really get much out of burning gear in. I mean I do, but I listen everyday because I want to... and over that time, it is difficult for me to tell how much it improved... because of course you can't go back and compare. The manual says 3 days opens up, 7 day more... I usually leave on for 10 days and call it done. So... I does sound amazing.
I put the stock tubes back in to break in and see what difference they make. Manual say 20% rectifier, 60% 6SN7s, 20%12BH7s? IDK. Right away I thought the stock tubes sounded pretty good. I did list to a bit. Still sounded great, but the magic was gone. Just everything diminished. It still sounded like it was voiced the same. Put my new JAN RCA 5R4GY back in... nope, that is better. Not like drastic, but you can tell. More weight, more texture. Next were 3 hole Bad Boys 6SN7s... Oh ya, there it is... it's back. everything was just much better. I do think it follows manual... biggest change. Next the 12BH7s had to go and back to my Mazda 12AU7s. Yep, magic. Just crazy.
I had stuff to do and did not have time to listen.... which is exactly what I did for the next 2 hours. I couldn't stop. No more endless audiophile crap... just started going through play lists. Modern Rock... basically grunge era. A-Chains, Soundgarden. I'm no big fan of Nirvana but their stuff sounds amazing. Something in the Way is just super spooky... Red Hot Chilli Peppers, Rage, Foo fighters, Green Day, Audio Slave... all of it was the cliched... brand new never heard it like that before music. I don't listen to it regulatory on good stuff... mostly MP3 workout... it's like a whole new catalog.
All my new Alternative..., Glass Animals, Neighborhood, Florence... hell EDM... Just nuts. Paul Oakenford "GO"... I literally thought it was a remix... never, I mean ever, have I heard "that" song before. Part of it really is because I never have spent a lot of time listening to good stuff. A lot was when I was training and crappy ear buds. I always listen to music in my vehicle and my system is really good. All active crossovers with DSP and 3-way front stage, Focal/JL Audio gear... but still, it's a vehicle. And... I have listened to my playlists with my old system and headphone setup... utopias even.
But what this DAC does, in a 2.1ch, with space, and stage, and holography... a realisim that is "alive"... just floored with what it does to my catalog of favs. Just can't wait to get back to it...
