I wish I had time to measure more amps but my test procedures are pretty consistent from product to product per my standard I use here: https://www.audioholics.com/audio-amplifier/basic-amplifier-measurement-techniques

Wow Pioneer has greatly improved its Class D amps since they dropped the ICE module according to this report. What an excellent test report I might add! thanks for sharing this. Now it makes me want to review a Pioneer/Onkyo receiver.

I do mention benefits of differential designs in several product reviews like this one: https://www.audioholics.com/amplifier-reviews/emotiva-xpr1-amplifier And on cables here: https://www.audioholics.com/audio-video-cables/balanced-vs-unbalanced-interconnects But probably need to do a...

We're seeing a preponderance of wireless Bluetooth speakers flooding the market right now that are either complete garbage or priced higher than most people want to spend for an office or spare bedroom. Enter Dayton Audio with their MK402 Powered Bluetooth 2-Way Bookshelf Speakers. They are...

I don't know of any "low cost" fully balanced amplifiers from input to output. Emotiva has some of the least expensive fully differential designs but most amps that claim "balanced" are nothing more than single ended with a phase splitter on the inputs. Please give an example of an inexpensive...

no, these are for recording voice nearfield only.

Harman/Kardon hasn't made a decent receiver in a very long time, especially multi-ch. It's not their core business.

We actually have a very close working relationship with Harman,but why deny history or pretend it didn't happen?

After a stellar 14-year run, Oppo has announced that it will begin the process of ending manufacturing of new products. Customers needn’t worry, Oppo will continue to honor warranties and will even continue out-of-warranty repair while also providing periodic firmware updates for its current...

I disagree, and it's partly why some manufacturer's of Class D amplifiers are getting away with this. Other than a filter to prevent test equipment from reading distortion wrong, regardless of amplifier class, the amp should still be able to swing voltage at full BW for 8 and 4 ohm loads...

I've seen prior class D amps from them rating power ambiguously like the example,cited in this article. If they update their specs with full disclosure of power and bandwidth with both channels driven, I'd be happy to update the article. There is no excuse to NOT have this information readily...

I have no boxes. Sorry.

This is feedback I received from this article by Bill Dudleston of Legacy Audio who gave me permission to post in this thread:

I am in Tampa Florida. They are almost 5 years old but I can't imagine getting the amp fixed would cost more than $1-200 tops. Well worth it.

MSRP: $3500/pair Asking Price: $950/pair I am selling a pair of Emotiva XPR-1 1kwatt monoblock amplifiers that are physically in great shape. This is the best, most powerful amplifier Emotiva has made to date. One of the XPR-1s works 100% flawlessly while the other stopped turning on recently...

Here is my FTC article: https://www.audioholics.com/audio-amplifier/ftc-consumer-audio

The Federal Trade Commission (FTC) purpose is to investigate and prevent deceptive trade practices. In 1974, the FTC instituted its Amplifier Rule to combat the unrealistic power claims made by many hi-fi amplifier manufacturers. However, we've noticed a trend of grossly inflated power ratings...

wait till you see my FTC article about this coming soon ;)

The TX-SR383 AV receiver from Onkyo provides a choice of native 7.2-channel soundtrack reproduction, or a 5.2-channel surround-sound layout with powered audio distribution to a pair of stereo speakers in Zone 2 . Rated at 155 W/Ch it seems like an amazing deal for just $400! Read on to find out...
