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.

[@MickeyMishra]

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!

[@crazyndn49]

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.

What, do you think companies just claim things with there being no backlash if found to be inaccurate? I understand that marketing can be misleading at times, but you could learn to understand that with variances in technologies, testing methodologies, setup fluctuations, and everything that could be a variable that literally having a standard that actually says what it should be in most cases doesn't make it "completely irrelevant" because some walking doorknob with a YT channel says "it's 1% different than what they claim", for your singular and likely skewed "reference"... 😒

[@Gmtail]

The TO-3 Cased transistors are certainly an oddity for an audio amplifier but there are quite a few N channel Mosfets that utilize that design but I kinda dig it because it's old school.

[@aaronatwood9298]

They were used in pro audio applications for many years, Peavey and QSC used them into the 90’s before phasing them out in their switch overs to Class H and then to class D. T-03 was super common in instrument amplifiers for the power stage. Very durable and it’s sad they were phased out.

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.

[@WareWolf801]

@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.

About the oversized speaker terminals. I assume. Imagine running your front stage with this amp. And its allll the way in the back of a station wagon, or some other long chassis vehicle. Which i think Stereo integrity acttualy did for one of its demo cars. Big gage speaker wire plus looong runs. No voltage loss or signal loss. 👍

Has the T03 transistors like Tru Technology , Mmats, and Linear Power.

TO3 is just the casing, not the transistor itself. I was corrected before, just sharing the info love 😎
