LSA Voyager GAN Amplifier

Who are you to stand in judgment of anything?

You seem to have an AX to grind with Wally and LSA.

I have just as much right to post an opinion as anyone else. I have no axe to grind with Wally and LSA, I am simply pointing out the less than optimal implementation and resultant load dependency of the amp's frequency response. Funny that someone should take a simple fact personally.

As I mentioned, this load dependency means the amp sounds different with different speakers, and even with the same speaker with a widely variable impedance. This can't be fixed with changing the topology of the amp's feedback circuitry. You can change speaker binding posts, add wood or springs under it, or sprinkle it with the tweakie scam of the day but that won't fix this deficiency. Maybe with some speakers, some will like the added distortion. To each his own.

I prefer and recommend an amplifier designed and tested to add as little to the signal as possible. That way you have a flat response to start with and can then toss your money to scammers who will add some distortion for you. Maybe you think it sounds better that way with a coating of kitty litter or what ever you are willing to believe will take it to 11 without anything other than confirmation bias or blind faith.

Where things head south is when one merely trusts.  Lots of folks out there who want your money.  Gotta be careful.  Verify!

Exactly! But the audio religion peddlers just want blind faith.

@kuribo So what do you recommend?

A bit off topic but I have a question about NAD m33 and Purifi.

Specs indicate same power into 4 ohms as 8 as I recall. Not sure what to make of that?  I could see where that was a factor in the results I heard with the small Totem monitors.

Whereas Icepower with a good power supply like BC ref1000m indicate power doubling mostly into 4 ohms along with significant current delivery capability. Both seem to indicate high damping.

THe ref1000m amps have been an ideal mate for my larger Ohm Walsh speakers in particular. I attribute that to some degree to the power doubling into 4 ohms, high damping and significant current delivery. Would not want to lose that.

There is no trophy in audio because none of these fake scientists have ever performed a test that has any meaning. It is really a belief system based on wiggles on a scope and numbers....all signifying nothing. It is a lie....plain and simple. I would not go so far to state that these people are all lying for they are just converts of this religion and believe it to be the truth. However, there is not one test that I have ever seen that correlates measurements with sound......none.....please show me one.

The Age of Enlightenment called. They want their Scientific Method back....

Yes, it’s a belief system based on science. It’s what’s gotten us out of caves and to the moon. What is your belief system based on? Your business model is "Trust me"- it’s a cash faith based religion which preaches results that can't be measured, verified, or explained by any rational means.

Engineering is indeed based on numbers. No one with any serious knowledge of science would deny the importance of math, physics, and rigorous testing/analysis to determine the performance of any engineered product, from bridges, airplanes, spacecraft, to audio. None of these audio products would exists without designers thoroughly familiar with the science behind their products. This should go without saying and I think any intelligent person understand this.

When someone claims numbers, science, engineering, etc., doesn’t matter, that it’s a scam, a religion, all faith, especially someone whose livelihood is dependent on denying anything that might give evidence of the veracity of his claims, it is an obvious and clear fraud.

There have been innumerable studies which verify the link between numbers and audible performance. Most people know this. You can measure the distortion from your tweaked out transistor radio and compare it to the distortion of a modern system and it’s rather obvious.

No, there is no accounting for personal taste. Some like distortion of a certain variety. That has been proven time and again. Others don’t. But I think everyone agrees that fraud, deceit, and making unsubstantiated claims to bilk people out of their money is bad.
