Lukasz Has Done It Again

If so that's 2 parts the akm chip is 2 chips not oneI guess it uses the same DAC chip
I suggest letting Lukasz follow his game plan for the very reason he described above. I promise the pictures will impress and the waiting will be worth it. Speculation and wish liats are good but as Lukasz says, "he bows to no one" in his research and development.
The 10 tubes will impress and for me I have "always"used my H360 preamp at full volume (63) into my preamp to then control the sound.
The first and most important difference is lack of volume control hence there is agan a need for a top class preamplifier. The new DAC is FIXED VOLUME. This is the FIRST MAJOR IMPROVEMENT OF SOUND - riddance of volume control. With volume control - the Horizon360 remains still our top product.

10 tubes is indeed impressive! but it can get expensive with rolling very very quickly. look forward to more details
this is exciting! esp when i skipped the 360 to see if there is something more delectable coming up not likely i think - the one used in the 360 is the newest chipset and the best one since the old akm factory burned down.
I would not miss it, Steve, nor the chance to see Lukaz and my good friend and colleague, Mr. Ainsley. Fascinating development indeed from the irrepressible Mr. Fikus
It is a redesign of the 360 board but the core concept and character is the sameThis is going to be craxy fun! Thanks Luksz for bringing such joy into our lives
NOBODy, but really nobody is suggesting to roll tubes, for me it is kind of like a slap in the face. And then 90% of our repairs is due to rolling gone wrong. It is VERY cheap not to roll and enjoy the stock tubes forever.10 tubes is indeed impressive! but it can get expensive with rolling very very quickly. look forward to more details
I think thats because most ppl dont have the knowledge to know what they are doing Luksz. For a manufacturer they wont be able to stock enough nos tubes to provide the best combination and I wont expect any manufacturer to be able to do that . While KR and old soviet tubes are not too bad - being in the game here Luksz - surely you do agree that nos tubes have a magical wonder to them . Not to mention...i havent blown my transformers once
. The new tube manufactuers just cannot master the old and lost arts of tube making - same as how old wires still sound the best despite upocc occ etcetc.TM with Elrog comes pretty close but yet the sonic characteristics of some tubes still remain quite elusive.
I also think part of the grief with ppl rolling is they buy tubes off ebay expecting them to work ; do not have a tube tester and just plonk them into the dac. No one can prevent such sillyness out there my friend; so i think what you say maybe can be revised to

and that gets a thumbs up any time of the day
I certainly agree that tube rolling is fun and addicting and that the old vintage tubes add something that is lacking in new tubes. But having said that this is a vastly different DAC. It is not an update the H360. Not everyone has your knowledge Ian and as Lukasz said so many of his repairs are a result of tube rolling and lack of expertise Lukasz knows what he is doing. Dual rectifier and 8 power tubes Gone are the dual triodes. For now I will be using the stock tubes and won’t be putting any of my old treasures in until Lukasz and Fred are here and give me the green light. Remember some stories here that one tube worked fine in a members H360 only to have the same tube take out the power supply in another members H360. There is so much different about this DAC that all I can say for now is “ caveat emptor “
The absence of dual triode signal tubes is going to make available some very fine tubes. To that extent many are unobtainium. To wit I have two matched Quads of TFKN EF802 with two dual adaptors from Laszlo. The other that becomes obsolete for me is the beautiful Star grounding piece designed by Laszlo with single strand extruded silver wire. These are amongst some of my treasure that I will be selling so if anyone is interested reach out to for details or come to the event as I’m betting they will sell to some attendees.
Laszlo is going to design another Star grounding system for the new DAC

I totally understand lampi I'm saying you don't need to roll tubes'NOBODy, but really nobody who has no idea of what they are doing and do not own a tube tester is suggesting to roll tubes, for me it is kind of like a slap in the face.

Take vac preamp or amps especially amps who rolls tubes ?
Regarding nos I think well made new tubes best nos . Even if nos test new how long have they bounced around . How good is the vacuum , were they used or broken in and then left for decades
I understand nos sound but nos makers also had many variations in production and sounds .
I always loved lampi for allowing people to tailor sound . But if a maker says there is no need to maybe better to leave alone lol
ahhh ok this has been floating around a while - correct me if i am wrong . star grounding is connecting all ground points onto one point ie like a star . in other words this is like common grounding , no difference to what most manufacturers do when they ground components to the chassis. Luksz for eg pretty much use common grounding on the tube boards in the dacs where there is a single ground wire coming out .
i think quite a few ppl then connect this star grounding to the ground lug on the lampi which is the worst thing to do. to illustrate earth ground also has a voltage potential which means that one ground can contaminate the other . in fact star grounding is the worst schema ever where you are exposing one ground plane to the other. Which is why in the shunyata altaire they seperate ground terminals and in the telos as well etcetc
Star grounding is just common ground and if the designer is not careful can make the sound worse
also grounding for tubes came about when i started using pathaudio resisters or in the case of c3gs where there is a can shield.We cannot ground tubes without a ground pin and also without an external shield. If laszlo is creating a ground plane then it would be possible in the circuit by having a cathode bypass and messing with the bias of that tube. I dont think that adaptor space can fit all that discrete components + on top of that the circuit board already does that so we shouldnt mess around with it at all. If indeed he has connected cathode to the ground in those adaptors - it is hardly a safe thing to do. + in the lampi dacs the ground wire for the tube board is already connected to the grounding lug at the back of the dac - so ancillary grounding on the level of the adaptor ....hmmm not sure. What we should be using should be discrete grounding . ie a seperate ground plane disconnected from earth ground for each grounding point. That i have used to good effect. If we look at some japanese gear - earth ground is not connected to components for a good reason. Now this is not about product safety because i know very well why we earth ground but for the sound - star/common and earth grounding is not what it seems .
If you look at the schema of all those tubes we use none of them have a ground pin.
Maybe Laszlo is grounding the anode wire - that i have certainly done to good effect using old nos tonearm wires in the adaptors i use in my rig but those are far and few in between + given the short short length of wire in the adaptor - it really doesnt make a difference so long as you have the geonetry of the wires right in relation to one another. I do these for long runs of wire where we need to connect up anode caps up top and in no other situation. Its not everyday you take apart a 80-100 yr old bakelite tonearm just to harvest the wires there for use.
If you look at the Japanese ..... new made tubes are very much out of favour. having said that why refer to the japanese - well they were the main ppl who bought and hoarded all the old tubes when the rest of the world were throwing them away or sing them for target practice on a farm fenceline ( also true!). Sad to say but even the new make we 300b tubes cannot compare to the old ones
