A new Digital Engine / processer is a must be a pretty significant improvement especially in light of the Baltic 3 being a relatively recent product. I don’t see the new processor / digital engine on either of the Lampizator web sites. Pondering what the cost of shipping to Poland could be $$$$$
The sound engine in Lampizator is a whole digital circuit: inputs and DAC. They do it in-house as far as I know.what exactly are these digital engines ? Do they contain off the shelf delta-sigma chip (ESS or AKM ?) or something in-house ? Just curious.
Here’s a copy of what I just posted about 12au7 tube rolling in the ‘tubes’ forum, might be useful for other Baltic owners
I have to admit a long love affair with the e80cc tube. It’s always been a fave of mine, comfortably outperforming superior 12au7 options in circuits where the extra current draw can be accommodated. One tube dealer describes it as being like a Telefunken ecc802s on steroids and I couldn’t have put it better myself - bigger / bolder / clearer etc.
In essence, not many know about this tube type and, when they do, the knowledge is largely restricted to the two ‘cooking’ versions from Philips Heerlen and Tungsram in Budapest. A fair bit of relabelling goes on e.g. Siemens / Valvo / Mullard, however if it has gold pins then it comes from Philips. The Hungarian Tungsram tends to have rhodium plated pins and holes in the plates. And that is what I have used myself for the past 15 years, with a few examples stashed away.
I recently bought two new pieces of equipment using 12au7 (Lampi Baltic and Riviera AFC headamp) and thought I should dig deeper into the back catalogues for superior examples. Without further ado, from left to right on the photo….
1) Telefunken G73r - a selected ecc802s with rfi absorbing coating
2) Philips SQ e80cc, regular late production
3) Siemens labeled Tungsram e80cc, regular late production
4) Tungsram industrial selected red label e80cc
5) Tungsram 1960 D Foil getter, pinched waist, welded plates e80cc
6) Philips SQ 1955 WK4 D Foil getter, pinched waist, welded plates e80cc
7) Tungsram 1958 nickel smooth plate D foil getter pinched waist
The evaluation was conducted in the Lampizator Baltic dac using EML 274B / Melz 1578 driven by Taiko’s Extreme and my best cabling options and I have been accompanied by the ever-perceptive @Blue58. Rather than dwell on the minutae between each tube, I’ll summarise the macro observations:
- performance runs from left to right, with big jumps at each end.
- the nickel Tram had an extraordinarily clear and structured presentation, resolution is a country mile ahead of all the others. My biggest dilemma with them is not the high price but the simple fact that they are already very rare but will be almost impossible to replace when they eventually wear out.
- thankfully, the cooking versions (3 & 4) are very satisfying as a daily listen and very cheap / plentiful. Big jump over the G73r
- The wk4 Philips has the most emotional connection and is a lovely listen.
- the Tak274b is too dense and homogenising to easily discern differences; the EML274 was more transparent
- talk of the 12au7 position on Baltic being unimportant is misplaced; significant deltas were observed.
This is a very good point. Lampizator makes tube rolling confusing in their own manual.- talk of the 12au7 position on Baltic being unimportant is misplaced; significant deltas were observed.
Not really reading their sentence as confusing (maybe as I'm not native ENG speaker). They are just saying they deliver with the current production tubes which they can source regularly and based on their tests those are best of the ones they tried (again current production) so no need to roll. But we all know rolling makes a big changes so we roll and roll and roll...This is a very good point. Lampizator makes tube rolling confusing in their own manual.
"We sell the DAC with the best tubes we can find in consistent sustainable supply.
Therefore we feel you should not be tempted to change them for any reason."
The key words are "consistent sustainable supply." All they are saying is that it is not practical to build a product around tubes that are hard to get. They are not saying that there are not better tubes to be had. The second sentence is just plain misleading since they follow it with tips for tube rolling...
I think that most of us with a Baltic 3 would also argue with the percentage(%) values that they offer for the contribution towards sound quality that the tubes in the three positions offer. All of those tubes can make a BIG difference. The rectifier can bring way more than 10%. I would argue that they should just drop those percentages as it makes it seem that only the 6SN7 is worth rolling.
I am just nit picking. This will probably be my last DAC unless I inherit a lot of money and move up the Lampi chain. The Baltic is a world class product.

You and I agree and your English is very good!Not really reading their sentence as confusing (maybe as I'm not native ENG speaker). They are just saying they deliver with the current production tubes which they can source regularly and based on their tests those are best of the ones they tried (again current production) so no need to roll. But we all know rolling makes a big changes so we roll and roll and roll...
I tried a pair of RCA 5692 red base tubes in the 6N7 position. The sound was dark, lacking life, drive density and energy, like the musicians were up way too late the night before. My tube supplier said well maybe I should try a pair of Sylvania’s or Tung-Sol’s. Anyone have a thought?
I went to nostubeshop.com and was going to buy a pair but their shipping charge was a killer to the ex-British colony AKA USA.... I would also strongly recommend the Tungsram e80cc and Padis fuse for their contribution towards ameliorating your concerns. Both of these are quite cheap.
Hi Doug,what exactly are these digital engines ? Do they contain off the shelf delta-sigma chip (ESS or AKM ?) or something in-house ? Just curious.
What is your source regarding engine #198?Anyway I read that Lukasz has said that all his DACs, as of February, will have engine #18 in them, and it is a USB programmable chip initially designed by another manufacturer and then modified by Lukasz. That's ALL second hand.
Both on the paperwork you receive with the DAC, as well as on its specs badge on the back (or underneath the chassis) there is clear info regarding the model number of its digital engine, tube set, etc. It has been this way since the very beginning (Level 4, etc).Owners are not going to identify their DACs by engine or date because they are not even aware of a change
