Stereo Integrity's Beautiful 200x4 SIQ-200.4 Class A/B Sound Quality Amplifier Tested [4K]

With the current price of lumber that box may be more expensive than the amp.

Nick has got a winner there! 😎👍🏻 Thanks BigD for grabbing one and sharing the results 😁👍🏻

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.

SO cool. Glad someone is still making amps that perform and look like this

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

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

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.

Reminds me of old-school amps from back in the day; Tru, Phoenix Gold, Audio Art, Linear Power, etc. Very pretty amp with some nice-looking internals!

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.

Who else had the thought of “that box could be used as a feeding spot for Beardie”? Anyone? Anyone? Just me? Fine I’m goin home then! Excellent work as always Wheelie

Just got the 125.4. These are on sale @ SI now and are quite the deal.

That thing is GAWW-JUSS!!!!! I think you just showed me my new favorite brand.

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

That’s really sweet looking insides I must say. Real good efficiency for Class A/B. Comes in a whoop ass case. It better sound good for that price! Go BigD! Stay safe mates!😊👍🏻😷

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.

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!

Beautiful amplifier

Gotta love SI gear. I'm slowly building a complete SI build. So far I have a single SQL-15 and real soon their M25 tweeters. Wanting to get 2 of their amps.

Big D deserves some focal K2s for the sq test
