The L1 is easily the most highly resolving and most transparent preamp that I have heard. Besides, it also excels in terms of functionality, offering more user-selectable parameters than I have ever seen on a preamp before.
It baffles me why the Bricasti brand does not pop up everywhere, it certainly should. Beautifully sculpted and with immaculate build quality, these components are not inexpensive but in context, they surely are also not extravagantly priced.
This Naiu Laboratory Ella power amplifier is the MK2 version with a new faceplate. While it looks similar to the amp tested in August 2017 on 6moons, this concerns a similar, yet further upgraded version.
