Hi everybody, my first post here.
I am home testing a Lampi preamp and it sounds wonderful.
It actually made me crave after a balanced Lampi dac.
I read about the new R2R option.
Anybody had a chance yet to compare it to current sigma-delta dacs?
TIA for your help.

Yes, I had both in-house for a while. The new Ladder PCM is more dynamic, but the old B7 with KR242 tubes almost matched it. Mind you, the old Dac was waaay more broken in, so maybe not a fair comparison?

My SE GG Dac is a killer…I am even more convinced after an extensive listen to a Schitt Yggy in a top system. The Yggy fleshed out a lot of micro details, but was far more ear fatiguing than the natural sounding GG. ALSO THE YGGY is PCM only and I can't do without high rate DSD,

I also got to hear AL's upgraded B7 headDAC WITH his newly installed and as yet unoptimized Infinity IRS V speakers. We heard some drum tracks that shocked the hell out of us. That with Chie Ayado's Tennessee Waltz and Markus Miller- Pluck held up the sonic illusion of LIVE. His HeadDac has the new ladder P CM. We rolled some tubes to good effect. I finally heard the EML Anniv 45 globes (solid plate) and his vintage 101d tennis ball globes. His Elrogs were out on loan…pity!

Hi Nugat,

The r2r option I added to my GGate was worth every penny. My PCM sound is really stupendous now. It narrows the gap between PCM and DSD for me considerably.

I had some tremendous results running PCM out of an Aries into the r2r GG with Kr 300b balloons and nos Philips 5r4gys recti - wicked combination of punch, speed, resolution, 3D, and liquid soundstage. I keep remembering hearing Wispelwey playing Haydn 2nd cello concerto - he was 3 ft into my room with the orchestra about 6ft plus in layers into my garden.
 
I can't wait to hear the new R2R PCM in the Lampi. If this narrows the gap between DSD and PCM - WOW!

It does narrow the gap but the gap was big between the 2 before IMHO. The DSD engine has a vitality and speed with resolution. The r2r has this vitality and speed now. It does not have that dsd extra natural silky top end, more of a standard PCM bite (if you know what I mean). Anyway - can't go wrong, Mike!

Side-topic: where are you guys sourcing your KR242 tubes? I can't find them listed on the KR website anywhere...
 
i'm quite interested in the R2R option for the GG DAC but I can't find any information on the Lampizator website. Is it now standard? If not, what is the cost?

I'm to buy a new DAC, but don't want to buy a DAC if there's a significant gap in sound quality between pcm and dsd. (I know that once I have a dsd DAC that if I hear that gap, i won't be satisfied until I upgrade or buy a new DAC, so want to avoid that!)

Hi Dave,

R2R is a no charge option for the Golden Gate. If you are interested in a Golden Gate, we are happy to include this for you.

Best,

Fred

Thanks Fred. I can see that I am going to have to give you a call. Thinking hard about the 211 balanced amps too 😊

Hi, Fred. I keep reading cryptic hints about DSD via the R2R engine in a Lampi, but I can't find anything concrete. Is the Atlantic implemented that way, or does it have the separate DSD and PCM engines like the other models?
 
Yes. The Atlantic DAC implements the new R2R Ladder for both PCM and DSD in an auto switching manner.

We're super excited about the Atlantic DAC with our only concern being that it's too good, lol.

Very cool. Any feedback on how the R2R implementation of DSD compares with the traditional Lampi chip less implementation?

On another note, I'm an owner of an L4G4 that has lost sound in one channel. I recently realized it is due to a loose or otherwise faulty tube. Is that something I can rectify by unscrewing the tiny Philips screws and somehow securing the tube back in place? Thanks.
 
Could be a blown tube...solution would be to replace. Could also be loose. First thing to do is pull it outcand see how easy it comes out. Next use finger pressure to spread pins out evenly with even, gentle pressure. Then reinsert. Does the tube now gpow when powered?
 
Thanks, Wisnon. I think the socket was loose, because when I went to check one of the two tiny screws on either side of the tube, I immediately heard the nut on the back side of it drop down into the DAC. Adding insult to injury, the tiny screw slid into the gap between the wall and also fell inside. I'm in contact with Robert via email and considering the options for a repair.
