Again, thanks @amirm for including another set of comparable measurements. This time the "Stereophile 50Hz distorsion spectra". Eventually there might be an informal standard set of measurements that "everyone" presents.:) (For poweramps My personal favorites are the 19-20kHz IMD spectrum at...

Thanks @amirm. Especially for the Reactive Load tests and 19-20kHz IMD. Most of the newer TI3255 based Chipamps are getting pretty good by now. These additional test may reveal differences that the now Classic sinad spectrum does not. This one was not bothered much at all by the load, (While...

If a guy were tempted to get a miniDSP 2X4 HD just to do simple HP/LP filter duty only... that wide band THD+noise @90kHz BW mesurement, (Thanks again Amir for going the extra mile ☺) should be enough for said guy to reconsider maybe using an analog active filter instead. I'm sure there are...

The reactive load testing is much appreciated, thanks for that!

Enter Hifonics/Zed audio "Varipower" amps. The ones with more than 50WPC were class G. Similar vintage as the Mac measured here. Gen 7 and 8 where the GOAT.

Better late than never... :) The LP part is supposed to be (18dB/Octave), there are inductors inside, so the "no distortion added part"...IDK:cool: But my experience with them in a car audio application was very positive. Would still consider using them to this day, even for home audio.

This intro used to be PRETTY fun in my car audio days. :) If you´re rocking something smaller than a pair of ten inch subs, there is a god chance you will have nooo idea of what I´m talking about

Yes, yes, that was my point too, but the smiley got deleted... :) Aah, there it is...

Dont forget the connectors on the drivers inside the speakers. 99 times out of 100 its a faston on a STEEL tab... ahh the horror.... :cool:

Stay away, "good condition" my ass. That is a spare parts donor at best. Also it appears the seller believes the on switch is a headphone jack....:) :facepalm: A better alternative: https://www.tradera.com/item/340874/586905698/rotel-rb-956ax-slutsteg

I have quoted some of your post for that very reason. Being Technically correct, reliable and also in my experience objectively presented without coloration from personal bias. And yes, the steel thing is a non issue, obviously at the other end of the speaker cables connected to that Buckeye...

@pma is more and more becoming my favorite contributor over here at ASR. Thank you for sharing your knowledge here PMA! Now that we have established that steel connectors can be problematic in this kind of application. I just can't resist teasing those of you that has a bad case of audiophilia...

I will bet my left testicle on that being a Mcintosh amp. :p

Hmm, I wonder WATT it could be.;)

Well it is absurd, yes. But maybe not in the way you suggest. In the Audiphool industry cost and performance does not always have correlation. In this case the OP-amps are not the limiting factor. (The TPA-Chip/Output filter is) and swapping them out is more like painting a Toyota with 10...

I can ENJOY music from almost anything, but I very much prefer it with the "being there" illusion of stereophonic audio. There is no good option in your poll for me. I would say I´m smack in the middle of "important" and "Nice":) Now having said that, a proper home audio system in my living...

Yes, their main function is to make the "features" list in the marketing material slightly longer, not kidding.:) And due to such marketing eventually some people may feel they "need" them, and may choose another product if they are not there. I use F1 or whatever they have chosen to call the...

Some encouragement for all the SIGMA´s out there, Probably sounds extra amazing on one of those Frankensteined Chipamps:)

When skipping forward in the beginning, at first I thought it was the funny hat and hairstyle convention...

Also we must not forget the Audiophool "formula" to figure out what is better, when comparing gear. Audible Difference+Expensive=Good Audible Difference + More Reasonably priced =Baaaaad, very bad... Also as a bonus we have the professional reviewer Formula: Regardless of audible Difference...
