1. You can buy light dimming led stickers on Amazon for $5 for 100 variations. I use silver ones on my Atma-sphere class D’s and other electronics because they are in my living room.
2. I moved from a Line Magnetic 805ia SET amp to the Atma-sphere class D’s and don’t miss it whatsoever. I leave...
Yes 805ia. I found that tube rolling progressively resulted in the amp sounding less and less 'tube-like', all in a good way. Getting the Atma-sphere class D's just took this process to it's ultimate conclusion ... :) I had even thought I might need to keep a tube pre-amp in the chain to...
While they don’t necessarily sound like a tube amp, I replaced a Line Magnetic SET with these about 3 weeks ago and do not miss the tube amp whatsoever.
The Atma-spheres do a 3D image better than my LM, and the space/clarity/depth around instruments is outstanding. One of my favorite things...
@shakti good point re B4 label still saying ECC82.
I guess I was thrown by this comment by Lampi, suggesting maybe more than just shipping with different tubes, eg. a change to the operating points inside the analog section: Another big change is in the analog section where big and bold 12BH7...
Thanks, so you are saying they are the same I think. But the B3 with engine 11 still took 12AU7/ECC82 but the B4 takes 12BH7 right? They have different plate currents and operating points afaik.
Ah, very nice!
One thing I am still confused on regarding the B3 -> B4 transition. There were a number of folks who got B3's with the engine eleven board. Do those also have all of the other B4 upgrades, but with just a B3 label? Or are they still missing some other running changes that got...
Hi, how did you upgrade from B3 -> B4? I thought Lampi NA had stopped doing upgrades/trade-ins?? I would love to upgrade my B3 to a B4, not just because of the DAC/engine improvements, but the resistor-ladder VC, so I could remove my preamp from my chain.
Interesting. So is this the JL Sounds USB card you are using in your DAC's ??? http://jlsounds.com/i2soverusb.html . I do see it mentions Galvanic isolation and the option for dual/separate power supplies. Wasn't aware of that.
Yes they are. I also bought a pair of ACME 805's and a pair of ACME 300B's from them. One of the 805's arrived with a broken internal filament even though well packed. The dealer got Psvane factory to replace with a new pair that has been functioning fine - and sounds great. I do wonder if...
$1325 + tax + shipping for a pair of Acme 300b’s? That $1500 to my state. I bought a pair of ACME 300b’s AND a pair of ACME 805’s from Hifi-amplifiers for same price all in. Nice to have the US distributor but hard to justify!
