New Lampizator Level 4/ Version 4 DAC in the house

L4 has potential but didn't like the stock tubes. It was too agressive and 2D.

I hope this is not true since I have one on the way. What you describe is not what I have read described by reviewers, and is definitely not the sound I am expecting. Are most of you current owners rolling tubes to get the best from your L4G4s?

my friend has level 6. he is so ecstatic. it lists for 10k.

You will love it. Tell me about which options you ordered. No worries as once burnt in you will love it!

Bill,
I thought hard about going with a Level 5 because of the dual mono power supply but since the PS on Level 4 seems to be overbuilt as it is,

we build a tubed power supply which is at least 400% oversized to provide the unheard of purity, authority and grunt.

and considering the DAC market is not yet mature, I decided to opt for the less expensive L4G4, which seems to be a fully evolved design for Lukasz. Once that was decided, I didn't see a need to change much else. My specs included;
1. Whatever rectifier Lukasz has found to be the best, in his opinion.
2. Additional USB input.
3. Change S/PDIF input from an RCA to a BNC type.
4. Duelund capacitors.
5. Black faceplate.

I decided it was not necessary to go with a balanced DAC. My preamp treats unbalanced and balanced input signals the same and then the signal is converted to balanced as it outputs through transformers.
I know you like the Jensens but I found the temptation to go with the Duelunds too great to pass up.
I will not know my rectifier options until I learn which tube Lukasz uses in my L4.
I am curious whether folks are rolling signal tubes in the L4. It is hard to find information on what is used and I couldn't find much on the Lampi site, but I understand he may be currently using NOS E182CC tubes, which are the same as CV5766, and perhaps 6N6P. I understand he previously may have used ECC40 tubes?

None of the Lamp dacs are flat and 2D. Not the L3/4 nor 5
