LSA Voyager GAN Amplifier

Great report/review Chorus!!!


IMHO, they should have named it David for all the giants it slays

One of the many things that surprised me was the V plays louder in my large room than the twice as powerful EVS 1200


Depending on when your V was made, it might have factory upgrades, which they’ve been including for a while now

cascadesphil,
That's generous of you to try to make videos comparing the modded Voyager to your EVS 1200.  Meanwhile, you must have heard the two amps by now, and maybe you can make a preliminary report.  Take your time before making the video.

Has anyone had experience listening to both the Voyager 350 and the LTA Z10 or Z40?

thanks

And these input buffers are usually $1 op amps.....not discrete stages.....this is true for AGD, Orchard, LSA, Peachtree, and Class D audio.

We have to be careful here. as I'm hand assembling 5 Orchard Audio Ultra Amplifier modules in a a single chassis with two 57VDC/14A Toroidal Transformers along with a 3rd one for some reference voltages. The Chips on the board (including the "$1" Op-Amps) were installed for me by a Customer of Leo's who's workmanship is excellent. I'm hand placing/soldering all the Surface Mount R's & C's and some easy to solder IC's along with big Output Inductors.

Anyway, since I am under NDA regarding the Bill of Materials (BOM), the $1 Op-Amps are actually $10 a pop x4 once each board ! Resistors and Capacitors are all 1% tolerances and I am adding Sonicaps at the output going towards the fully balanced (XLR) output connections in place of what Orchard normally recommends.

Those who Shxt on Class D should have a proper listen to an Amplifier module that's designed form the ground up. The second iteration of last years BOSC (now StarKrimson) increases power output, uses a different GaN chip, and has been improved upon thank's to Leo's efforts and customer input (i.e. it's a Joe Poof....uh I man Proof) design.

Those $10 each op amps are still standard op amps.....he just choose some particular ones for low noise that are more expensive......they are still a bunch of transistors running really low bias and have protection diodes that screw up the sound, etc.  This is way different from using high bias discrete op amps or circuits........really great discrete op amps/circuits just plain sound mucho better than even the expensive chip op amps.  Some of the other things you describe are not stock....you are building a one off thing.  No one can buy what you are building.  Sonicaps are good but not great.  Way better caps out there.....including my modded Wima caps.  There is always more......much more.  We have only just begun.  

Even though the Voyager/Peachtree has $1 op amps in it....it has been tweaked by many people for great sound over a couple of years......this module is really good.  I am sure the StarKrimson modules are good too.  No doubt we will have a shoot out between a stock Orchard and a stock or modded LSA/Peachtree some day.   By the way, I can mod the Orchard amps, as well.
