Berkeley vs Bryston vs Lampizator

From my Lampizator dealer friend:

For 2017, Lampizator discontinued L4/L5/L6, and now have 3 DAC lines: Amber2 (better than L4 was), Atlantic (better than L5/L6 was) & Big7.   There are different options & versions of each including top end Golden Atlantic and Golden Big7 is Golden Gate.

I had Atlantic in my system and is very good if seeking a little tube magic.

I owned the Berkeley Alpha 2 for two years, fed by their Alpha USB.  I next changed to the Lampizator Big 7, also fed by the Alpha USB.  There was no contest in my system:  the Lampi had much more resolution, which is interesting, but most importantly it was more organically musical, more harmonically full and truer to live instruments in timbre.  Also the Lampi's soundstage was bigger, fuller, with images that were closer to 3D, more palpable.  Like I say, no contest IME.

I have since moved on to the Lampizator Golden Gate, which is sort of the Big 7 with premium parts - - even more magical, and worth the cost difference for me.  Currently, I am done trying DAC's.

Never heard a Bryson (or a Bricasti).

A Berkeley Alpha 2 isn't cheap. How much can I can expect to pay for a used Lampizator?  Any recommendation on what level to buy or avoid?  

I'm sure there is a Lampizator sound throughout their whole line. I'm sure that the newer models may be more refined, but the basic sound remains. The Bricasti was just fuller and more organic sounding than the Lampi. I had.

If you think Bricasti has a big price tag, last I looked at the Berkeley, I believe that is is almost double the price.
