Someone please school me. Is the "premium" version even better than the Lehmann BCL?

How's the build quality? Sharp edges? Solid knob and jacks? How many days to arrive?



3+ weeks. Solid Knob and Jacks. Crappy supplied power cable and/or receptacle. Will try another cable later. Edges are fine and the build inside is clean and detailed. So far I really like the sound with the HD650s. It has taken some of the darkness away from them.

Lehmann BCL:
 

The transformer and volume control part looks so different, plus BCL is fully discrete (if I'm correct..) while LC is using OPA627, they may sound quite different.

BCL uses OPA2134.

You are mistaken.  That is just some wordsmithing used by Lehmann in their adds.  It uses an opamp also, just soldered to the board so you can't swap opamps.

^ aha, was suspecting that too by looking at the pic, actually the 'fully discrete' is seen somewhere else during google-ing but not on the official site.
 
..and oops, the LC is also using OPA2134, OPA627 is the upgrade kit.. my bad

Your info is correct.  I think Lehmann changed the wording on their site after a few audio sites including HF made note that with the use of a opamp, the circuit could not be "fully discrete".

Here's the inside of my Lovely Cube premium. The premium version comes with the 30VA Toroid, the higher quality gold plated neutrik jacks, and higher quality RCA jacks. I opted to upgrade the RCA's to all copper units like some other guy here because they look so cool! Stephen also sells stepped attenuators but since I hate clickies I didn't bother but for $10 dollars it's a pretty good deal.

Got a response from Stephen. No review sample for me. :frowning2: maybe I'll buy one.
