    ATI (Amplifier Technologies) Owners Thread

    ...those things are due to power amps in the calibre of those you are looking at, if someone says they could hear the difference between ATI's class D and AB, I just smile, knowing full well, with confidence that they would not hear the claimed differences in a well controlled DBT, I respect...

    Is the Onkyo TX-RZ70 the Best AVR under $3000?

    I was just looking around for the same information.... sadly Onkyo/Integra have not been quite as forthcoming about the guts of their gear as D&M have!

    Parasound A21+ power amp for my front L/R speakers -- overkill? Other options?

    ...for $2500 is also the cheapest version of it. The Ultra is $4200 and it can go up from there with options. What I don’t like is all these class D amps like the one we are talking about has a 1 year warranty (WTF). All these class D amps have a much smaller warranty compared to traditional amp...

    Bryston Class D Amplifiers

    Gene wrote: “The Axiom A1400-8 is a Class D switching amplifier” so that’s why I thought it had a switching power supply. :D So kudos to Axiom for using a giant power supply even back in 2009. Since Bryston and Axiom are owned by the same two Canadians (James Tanner & Ian Colqhhoun), I think...

    Yamaha AVENTAGE 2021 AV Receivers Bulk Up on Power and 8K Features

    I recently stepped down from external power amps (Crown XLS2500, 440W@8ohm, 1200W@2ohm) to my new Denon X4800H (125W@8ohm) - and I am happy to say the system sounds as it should. My previous Integra DRX3.4 did not sound right with my Gallo speakers, which do dip down to 1.6ohm and are a...

    I think I would add 'mind' to the quote about ears breaking in- bias comes from the mind and the interface allows us to smooth out differences in sensed experiences. Then, we get to deal with the conflict that comes from "This can't possibly sound this good- it's not expensive, big, etc" due to...

    Parasound A21+ power amp for my front L/R speakers -- overkill? Other options?

    Was curious, so just checked what Bryston is doing with their class D offering, looks like they're still doing 20 years. My Crowns came with 3 year warranties but not an issue since expiration, some are 15 years old now in daily use.

    ...EPDR (a misleading spec, that says more about heat dissipation, than currents). That, from my understanding, you may be better off using class D amps such as the popular Hypex or Purifi modules based power amps. Class D amps seem less prone to low EPDR than class AB amps that would...

    Parasound A21+ power amp for my front L/R speakers -- overkill? Other options?

    ...new setup and the aesthetic my wife was looking for with the new console. The previous setup had very low WAF. One nice thing about these class D amps is how easily they will fit inside the console. The McCormack DNA-1 Deluxe Edition amp on top just barely won't fit in the console. It...

    Interesting comment by Gene Delasrio in his review of LBM speakers....... "Class-A/B may not be quite as efficient as class-D, but it is more reliable on the whole, and with such a massive heatsink, it looks like a unit that was built to last."

    Parasound A21+ power amp for my front L/R speakers -- overkill? Other options?

    Very nice setup, your front 3 speakers surely love current! They will do well with Bruno's class D amps. By the way, Bruno is main guy in the design/development of both the Hypex and Purifi modules, here's a good article that he and Gene worked together on a few years ago, don't let anyone...

    Focal Aria Evo X No.4 Loudspeaker Review

    I don't see an issue with the aforementioned amp modules for any of Focal's offerings. Their measurements have no issues with 2 ohm loads. I'm not a huge fan of Focal's design implementations but these amps will do fine. Unless you want to put some extra money into a couple of AB amps on the...

    Need a new three channel amp.

    There are plenty of AMPs available in the US available for well below your max budget, AB, AB hybrids, G, H, and Class D. You definitely want to make sure that your amp has failed and not another component or speaker so you can appropriate money correctly. If all 3 channels developed the same...

    Looking for schematic for Cambridge Soundworks P300HD subwoofer

    ...the boards are now made by robots using surface mount components, again installed by robots. The the third issue is that these ubiquitous class D amps, are very complicated and a nightmare to work on, even under the best of situations. So, that is why I have so much vintage equipment, as it...

    Amp protection lights on

    If I would buy a new amplifier then a good class D is what I most likely would buy, and as @everettT wrote low heat generation is important to me as well. Also note that an efficient power supply is very important as well as most of the time the amplifier will output low power (1-5 watt or so)...

    Favorite Amplifier that you could buy, but don’t buy…
