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.....

Hi All,I just joined the group after reading this thread. I read a lot of good about the LSA Voyager amp being sold by Underwood Hifi. They also are offering a less expensive model called the Discovery Warp One. Are any of you familiar with this one yet? Would anyone be willing to look at the specs they give on the website (https://www.underwoodhifi.com/products/lsa-electronics) and comment on how this should perform compared to the Voyager? The Voyager is way out of my price range, but the Discovery Warp One is just right. I am considering it along with a Parasound 2250 v2. The system I will be paring it with is: digitally stored music sent through a Cambridge Audio DAC, then to an SAS Audio Labs tube preamp, the amp, and finally to Martin Logan ESL speakers with a Martin Logan subwoofer. I know this system is child’s play next to what you are all used to, but it is the best we can afford.Thank you!
I'm not familiar with the Texas Instruments "Purepath" class D module, but it evidently isn't a GaNfet design, which seem to be producing the best sound these days.
I have a Fosi Class D amp that uses a TI chip.  It sounds very good.   A bargain. 
Hi, been lurking for a while, and enjoying the posts....

The LSA Warp One uses the TPA3255 chip, with proper power supply can do 300wpc. But it also doesn’t measure quite as well as some of the other tech (especially Purifi and GaN).  

I have enjoyed playing around with a lot of inexpensive amps using various chips. I have also owned Ric’s EVS1200 (and 4 other of his products), a few amps (DIY and one from VTV) using Purifi modules, as well as the Orchard Audio GaN mono’s and Stereo Ultra.

I WILL say that a cheap ($60 w/o brick PS) 3255-based ChiFi amp I got sounds quite nice for that cheap $; this and several others are indeed bargains, but would certainly be bettered by better implementations of likely better chips. None of the amps I have tried get to the level of the EVS1200, Purifi, or GaN amps I have or had. But they get a decent % for TINY money!

If what LSA does is greatly improve the pieces around the 3255 chip, then the Warp One may still be worth it. But I think it may be a bit too pricey, and my belief is that the Voyager will be better enough to warrant saving up for it. Or....look at some other slightly less expensive GaN options that Ric had mentioned previously (I am definitely a fan of Orchard products).   [EDIT: looked at some of the design notes and specs on LSA page, and it IS impressive.  I still believe that the GaN will sound even better though]

To me: a well-modded Purifi-based amp, or well-implemented GaN-based amp, are the best I’ve heard. Makes me miss tubes and Class A not one bit.
Forget the money--these are all decent amps for sensible money.  Decide what kind of sound you want.  I await tweak1's evaluation of the Voyager vs his EVS1200.  My Rouge IceEdge 1200 AS1 amp at 260 hours is neutral, which is similar to the EVS1200 without the mods.  I'll find out soon when I do the mods.  The Voyager GaN is more tubelike, according to the people here.  My experience with the Merrill Element 114 GaN is that it was tubelike.
