Hi Yetis,
Happy Thanksgiving!
Is there any update on timing for the balanced xlr version of these amps? Also, is it possible to get an extra set of binding posts, for a full bi-wire output.
I've explored this - just forgot to post about it. I can make the Lilianas with XLR inputs currently without the tube stage.
I'm pretty sure I can also configure the tube stage for differential use. So if this is something that you require, please let me know
and I can configure this custom for you.
Yes - I can fit an extra set speaker posts in there for bi-wiring.
And just any comments on how you decided on what class d amp design to use?
The Liliana uses a discrete Class AB MOSFET output stage (8 output stage FETs) -
not class D.
The tube input stage is Class A.
As you move up the power band and given the warm reception the liiana have received, do you see the possible application of more powerful amp stages? I assume it is a battery capacity, but it sounds like this could be addressed.
It's really not an issue of battery capacity. Larger, higher voltage packs can be made. It's more a question of "how many people would need more
power than the Lilianas?" I'm guessing not many - and the other issue is more cost, and we'd probably need larger (e.g. Signature 57 sized) enclosures for each channel for higher power.
On this last point, the review you posted amp shoot out suggested you could make a second battery pack. Does that assume that the Black Lightning would work with these amps? Would you be able to do that with multiple outputs, to support three amps?
The Liliana's get up to 8 hours of playback on a full charge (running in pure battery mode). Of course one can play and charge in "AC mode" with no time limit for background listening. But if a customer needed more play time in pure battery mode, we can made an external "Black Lightning like" enclosure that would fit higher capacity batteries. It would be custom, but it can be done.
Thanks for all the good questions!
Vinnie
