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.....

" Last week I got the mini GAN from class D audio. I have been very impressed with this little amp. I also have the Carver Crimson 275 tube and Van Alstine synergy 450 SS amp. Frankly I like it better than AVA amp and as good as the Crimson 275 with much more power and bass impact. I have also ordered the Voyager 350 and waiting for its delivery."  

Thanks for the update.  I have the mini GAN too (for a bit) but I just bought it for HT as it is easier just to swap speaker cables when I watch a movie (my main system is an integrated AV system).  I broke the mini GAN amp using my UHD HT listening to 2-channel files via my Panasonic 9000 (which goes into a Sherbourne preamp and then out to the amp).

I didn't do detailed comparisons (have old B&W P6s as mains in that system) vs. the Mivera SE amp (with upgraded fuses) but could tell it certainly was somewhere in the same league.  At one point I had the Mivera in another secondary system (in a small bedroom) where it trounced an old Bryston 3BST right out of the box.  The Mivera then went into the main system where it bettered my Modwright KWA150 SE (which had bettered a Bryston 14BSST I owned before) and now have the EVS 1200 in the main system (driving Thiel 3.7s, Modwright LS 36.5 DM preamp and Lumin U1 music server) which was better than the Mivera.

I am still amazed to this day that the last two (IcePower) Class Ds were better than the Class A/AB amps both in sound quality and driving the Thiel 3.7s (and given their impedance I am still amazed - https://www.stereophile.com/content/thiel-cs37-loudspeaker-measurements).  I had Thiel 7.2s before the 3.7s which were a tougher load (base on experience with the Class A/AB amps noted above and others).  About 7-8 years back I heard Class Ds at an audio show and while they had come a long way, at that point in time they seemed to run out of steam driving some speakers.

I do think that Class A/AB at some point will become undesirable for most (e.g. https://www.theabsolutesound.com/articles/mbl-noble-line-n11-preamplifier-and-n15-monoblock-amplifie...) given how Class D is progressing.  There is one used KWA-150 SE on hifishark right now for with an asking price of $3,457 ( https://reverb.com/item/36606380-modwright-kwa-150se-stereo-power-amplifier-signature-edition-kwa150...)  Given the fact it is a current model that lists for $9k and I've seen other used listings at $3.5k or below, I'd think that for those who objectively listen (vs. those with no experience and prejudice based on hypothetical theories - and there will always be a bunch of those - I wouldn't expect those making more expensive Class A,AB amplifiers to agree as it is not in their financial interest) the word is spreading.  It may be a bit before Class D starts to compete with the likes of Constellation, VAC, Boulder, D'Agostino amplifiers, etc., but it has come a really long way.
After reading what corepowertech said about the care and testing that went into producing this amplifier, I feel that if increasing the wire diameter would have increased the sound quality it would have been increased. Probably less than $1 cent total cost.

Most amp designers/builders are trying to produce an amp that does one thing: produce an output that is as close to the input as they possibly can, only larger. That's what an amp is suppose to do, by definition. Anything that produces a noticeable change in the output, unless it can be shown to be a truer representation of the input, is noise. It may be that some like that noise. It may be that some don't. It may be that the noise is too small in magnitude to matter either way. All of this tweak nonsense assumes that every change is audible to all, and that everyone will agree that the new output spectra is "better". All of this without any factual basis, just "trust me". Are people really that gullible?

kuribo,
You are one of the few people on any Agon forum to agree with me that the ideal of high fidelity is best achieved with neutrality/transparency.  The "straight wire with gain" is indeed what an amp is supposed to do. Good for you to imply boldly that coloration is just noise.
