Just a few. Not much info but here's what I now of. The vintage Mics I've used essentially were wired for triode operation, and the designers just stuck a dual-FET "tube" in place of the triode, and output it into a MOSFET setup. LI could also stand for low impedance on this case, as FETs are inherently high impedance, but doubling them up and running bipolar current through could make them more efficient. Not really something I know a ton about though, info is sketchy even on the pro audio side of things. (I'm just a lowly music student though, so take it all with a grain of salt XP)

Thanks for the info TPM!

I guess it's sorta like how you can put in different opamp chips in some amps like the iBasso portables?

A little. From what I understand, the FETs are essentially replacing the vacuum tube. The benefits in theory should be a harmonic distortion curve more closely resembling traditional tubes but with more linear freq. response and lower distortion numbers, similar to transistors. A theoretical "best of both worlds" I guess.


If the LI is indeed lithium ion, the electrolyte battery may be functioning as some sort of capacitor? That's pure speculation on my part though.

Using an FET to replace the function of a tube is standard solid-state amplification.

  Combining a MOSFET output stage along with a Li cap array used as a storage medium for impulse response could create some interesting topologies... but again, I'll wait and see what Master Baldr says.

Kind of along the lines of what I was thinking! Will be excited to hear about them as well.

Btw, hope you are feeling well Ableza, I know you said a health issue prevented you from attending.

Hey thanks to you and to all who sent good wishes.  I'm fine, just recovering from some surgery.  The hassles of getting old.  But I sit here listening to Neil Young and Crazy Horse through my Alpha Primes amplified by Lyr with Gold Dragons, DAC by Wavelength.  All is good.

Glad you are on the mend! I resemble your getting old and surgeries comment. really wish I had been a golfer instead of a linebacker, they are still trying to put me back together

I think Schiit is going all retro with their new products and the news release will be in morse code.

  Does the Mjolnir 2 automatically turn off the preamp outs when you plug a headphone in? I don't seem to see a switch for controlling the outputs.

Most Schiit amps do not do that.

Lisst solid state "tubes"

OK,  "Linear," not "Lithium."  So basically a plug-in FET instead of a tube.  Cool.  Clever design.  But not for me.
