@@1andonlyjoeyb534 No actually they are not. They are not a rebadged SI amp. Big D and HI Fi Vega both did separate reviews of those amps. They were cheap knock offs that looked pretty. However the components inside were not the high grade we have just seen here. They came know where close to rated power and sound quality was poor. It was a pretty enlightening episode on both KZread channels.

That's one of the nicest looking amps I've seen in a long time, and I've seen a lot. Reminds me of my old "ear candy" Linear Power amps I had when I was a kid. But prettier. It would be even cooler if they used the metal case componants on the power supply also, it would be even longer.

Love my SIQ amps. Just nice clean power houses that look great! Great testing Dereck, love seeing what she actually does. I was only able to review their sound and not true power.

I like that they named it based on the 4 ohm rating. I think all 4 channels should be like that

You are 100% with the class AB and Grey Poupon analogy.

This is one of my favorite in your collection. Beautiful amp. I bet it sounds good!!🤛🤛

Why get a Krell, when you can get this! LOL! That amp is so well laid out and is some very pretty work indeed. As far as cost? $1200 is a DEAL! Getting those parts alone would cost you that much! I wonder if they make a Black Label version that has Esoteric parts in it? From what I can tell? This seems to be a great investment and a LONG term winner. Amps back in the day cost way more. This seems to be Budget if you ask me from what S.Q. amps use to cost to own. I like the fact they did not bother with crap in the signal path that need not be there. I have to admit, I would like to see a Crystal or Quartz Glass or Automotive rated glass cover for a Signature model of this amp in the future. Maybe in a future statement release? What amazes me is that the price of a S.Q. Amp is a Con at this point? You just can't get this level of parts quality at this price so I don't see how the price is con! Its a FANTASTIC VALUE! Thanks for showcasing this Amp Big D!

Have you thought about hitting up SI to see if they'd send you the other amps to test? They seem pretty straight forward with everything and I'm betting they'd try to fix/update anything that wasn't up to par for the masses. I'm saving pennies for a build with their parts, I can't wait to get ahold of all of it.

Great video. Big D you are one RAD dude!!!

Big D deserves some focal K2s for the sq test

Beautiful amp. I do love the SQ stuff. It does cost a lot, but compare it to a similarly powered home amplifier, and the price is not too bad for an amp capable of 4x150w in 8 ohms (certified), or 500w x2 in 8 ohms bridged.

The ultimate Midbass amp. Bridged down to two channels.

@BigD: We know that you're into that killah bass. We all love that. Using bookshelf speakers along with a gigantic sub, shows that you're interested in home speakers too. So, try this out for us, if you would: make some (3 or 5 pair) of speakers with various sizes of exciters mounted to matching scale-sized foamboard. Then, team those with a powered home sub. Test the frequency responses to see what combination from the various pairs is best. With exciters, do they benefit from bigger panels? Seems like higher power exciters would be able to "drive" bigger panels or reproduce lower tones, but I could be wrong. These components are super cheap, but we (your viewers) don't have any testing equipment to try to measure the frequency responses. If what you're powering doesn't make a flat response curve, it won't sound right. If that curves varies much (up and down the measurement scale), it won't sound right. Now I realize this is a bit off your typical testing regimen, but even if you measure subjectively at the clarity added by introducing a 2nd, 3rd, etc. pair of exciters to the show, it would be pretty cool. Since you like to mess with boxes, and the like, this might be interesting to you. Dayton Audio (and a few other companies) make a couple styles of exciter that utilize various power amounts as their intended input peak. From the styles I've seen, ribbons and pucks seem like the two most common technologies. Sometimes the pucks have feet that extend off them, but then you have multiple points of contact you have to adhere to the foam board, but whatever, if it works. Anyways, this might be a rabbit hole that you would get a kick out of, and have some great speakers when you're done. You can mount exciters to nearly any surface, but the foam board lets the voice coil in the exciter actuate the foam and vibrate it; similar to how a "cone" in a traditional speaker works. There have been some significant tests performed to see what surface works best, and the foam boards are cheap and very functional. I've actually bought a handful of bluetooth speakers that use this technology, and it's pretty amazing. Even tiny exciters can make hard surfaces bump.

I have the 125 x 4 version of this amp. It’s very good! I love class A / AB amps for home and car!

Could you dyno the power Acoustik VA1-6000D. I'm really curious to know the bench results

As I mentioned before class A is 0.000001% THD and class B 0.003% THD from what I can remember in the 1980's, I have not seen 1 car amplifier that is lower than 0.01%THD. Where they get there classification from is anyone's guess. It is a class D amp at 0.03% THD. I have a LANZAR Heritage HTG668GBT that has lower THD, 0.01%. THD is the first choice for pure quality, then comes frequency response. The greater the lower and upper frequencies the more representation between.

Thats HOTT! Are the toroid shielded with that copper or is that the help with Cooling?

Just curious about the temperature? Kinda thought they'd have a fan in there 🤔
