New Lampizator Level 4/ Version 4 DAC in the house

Wonder if any other new owners of this DAC are out there as I find it to be the finest digital playback I have heard to date. This is the first digital front end piece of gear I have owned that has transformed my music.

Ya, other digital gear does this or that better, but this Lampy breaks through to a new level of musical enjoyment. Clear view into the music helping the speakers just disappear. Only 24 hours of break in and the music flows so sweet, intimate and seemingly without boundaries.

Looking under the hood I see an impressive power supply with films caps and several high quality chokes. Point to point silver wired except for the digital and USB boards. This is a three tube player that is tube rectified. One has the option for SS rectification if desired.

Ya, I love this Lampy!

Kng, You are correct (I was wrong, mea culpa). While there may be local computer "buffer" its not that critical as the signal still has a ways to go to hit the Dac.

After investigations, there IS indeed a Ram buffer located in the SB-R, similar to buffers in DVD players. The buffer is very fast RAM memory and is located an inch or so away from the tube output, so a TRUE buffer, for about 4 seconds (I believe). This is the basic architecture of the SB-R and not unique to the TranspOrt.

The Squeezecentre player may also be storing info on the computer before sending via wireless or LAN cable, but would not be a true buffer, as much can happen to screw up the signal before it gets to the Dac, given the USB cable transmission and the stock SBR processing.

Wisnon, Computers have been using buffers/cache forever to improve performance. This is true in both hardware and software.

From Lamp Web Site:
Once again - how can a "stupid" computer modem sound better than reputable real CD transport ? Computers are supposed to be BAD.
I will try to explain how I see it:

Just imagine: It thakes 70 minutes for the Philips CDM2-Pro mechanism to read all data from CD disk. The same amount of data is read by DVD drive in 2 minutes. Blue Ray reads it in half minute. Hard drive reads it in 4 seconds. RAM buffer reads it in less than a second. MY LampizatOr Transport plays from own FIFO RAM Buffer.

The Data from CD must be read by a laser, which constantly needs to adjust focus, servo adjusts linear speed of motor, and track tracking. The data is demodulated from laser waves, and missing bits or errors are interpolated and corrected. Vibrations make reading difficult.

The HDD Lampizator Transport player needs nothing of that. Perfect, 100% accurate data is fed to RAM buffer and just (FIFO) - sent out to DAC according to external precision clock.
This scenario is 100 x more simple, errofr free and accurate. I am surprized that CD players play anything at all ;-)
This is what I've been saying for years but Lukaz has the numbers to support it.

"Perfect, 100% accurate data is fed to RAM buffer and just (FIFO) - sent out to DAC according to external precision clock."

Lukaz recognizes the benefits processing from RAM so just can't imagine there is no mod to the stock SB FIFO RAM buffer.

It looks like the Lamp had a volume control, was it ever run direct to his amps?

Abruce, yes it was because the Dude preamp needed breakin.
