LSA Voyager GAN Amplifier


Just got mine last week.  After 24 hours of play all I can say is that this is not your father's class D amplifier.  There is not one thing about its sound that reminds me of the class D gremlins that I do not like.  The low end filled in and now has deep impact, the midrange is the love child of a beautiful tube and clean hybrid amp - just gorgeous.  Highs are very clean and extended. Spatial cues are top notch. My system has had some damn good tube and solid state amps in it before and it has never sounded this good.  I am blown away with the quality of sound coming from class D amplification at this price point.

This 300 wpc amplifier is a real winner.....

Vibe,

Some clarifications:

The Voyager I have is stock.
A friend just sold his Pass Labs 30.8 Amp and bought the Voyager.
I use a Pass Labs INT25 which is fairly close to the same as the 30.8
so his move caught my attention.

My setup consists of:

-Late 80's Tannoy FSM monitors with XOs rebuilt by Danny Richie.
-Innuos Zen MK3 Streamer/burner/storage
-Audio Mirror Tubadour DAC with reclocker upgrade.
-Uptone Audio EtherRegen

On loan:
- Wyred for Sound Preamp-fully balanced as is the Voyager.
- XLR cables.

My room is mid-sized with good acoustic treatments.
I listen from 55-70db only. 
Mostly Blues & Vocals. 

My comparisons have not been against other $3,000 Class D amps
with say 200+ wpc. That would have been optimum for a legit comparison but no one I know near me owns one.

I have been told by the same friend who bought the Voyager that he
has listened to the Merrill Audio GaN Amps. He felt Merrill Amps did
have slightly better SQ than the LSA product.
However at $15k-$25k for the Merrill vs. $3k for the LSA let's hope so. He could afford either and he chose the Voyager.

My goal is simply to find out if I prefer the Voyager over my Pass INT25.

The other amp I compared it to is a Lejonklou Boazu INT-$4k.
The Voyager had not yet been fully burned in at that time so
I must discard that result.

I also own a Line Magnetic 218IA Integrated Amp, EL84,
7wpc, flea power tube amp. I prefer the Voyager's SQ
over than the Line Magnetic.
Again it is not a fair/even comparison.

The Voyager I have now has 350+ hours on it. In my experience it
needed 200+ to reach 95% of it optimum SQ.  Like most of my gear
it produced perhaps 70% of it final SQ right out of the box.

I am still performing more comparisons so I am not ready to make
my final comments but can say:

-My senior sound engineer recording studio friend brought over his own symphony recording on CD. He is intimately familiar with it naturally. He liked the Voyager overall very well and felt it presented his work
very well.

My initial findings:
1. The Voyager has great presence.
2. The Voyager has strong Bass
3. The Voyager is simply fun to listen to.
4. It will be a hit with Rock & Roll lovers Bi-ampers, and JBL type
    speaker owners should investigate it.
5. For Two Channel Home Theatre I would doubt it can be beat.

To say Underwood HiFi has hit a walk-off home run with this
new product is not an exaggeration. 

Bring on your insensitive speakers with low ohm ratings.
Bring on your larger rooms. 
Bring on your Bass loving listeners.
Bring on your home theater,  2 channel sound folks.

This Amp may make a lot music listeners into music lovers.

As with Ulysses the Voyager may be your siren's song!






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

hth
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.
