Care to expound? 1 watt is 1 watt is 1 watt, provided distortion levels are beyond the threshold of human hearing. I listened to the RF7 with a Sonic Impact t-amp MANY times. Never had an issue- could not be distinguished from Carver amplifier in a blind test.
I know this topic has gotten beat to death on these forums, but it still fascinates me. I probably would not hook up a nice speaker at all to the PYLE amp- Just based on product reputation, but assuming one functions correctly, it should be indistinguishable from other amplifiers.
That said, I'm a fan of having products and paying for products that are built well, built to last, and find value in those features.
Sure! Let me try to explain myself better. I will 1st start off by agreeing with you that 2 things that are identical are, indeed, identical. So, yes, science says that 1 watt in box A is the same as 1 watt in box B.
What I should have said is - All watts are not delivered/executed equally. I will give some examples.
The BG Radia PD-6Ci
http://bgcorp.com/PDFs/PD-6Ci-literature.pdf is one of the absolute best, most unique sounding -in-ceiling/wall speaker I have ever heard. They are excellent, with a distinct way of delivering music! They sound incredible, with real bass and a presence that radiates in your ears.... if powered properly. When not.... they lack dynamics and sound dead - gross, actually.
I have a pair in my master bedroom ceiling run into a small closet. I switch amplifiers in and out to play around with these all the time.
This:
http://sonos.com/products/zoneplayers/zp120/default.aspx?rdr=true&LangType=1033 sounds excellent at all volume levels. 55watt a channel digital amp.
This:
http://onkyousa.com/model.cfm?m=TX-8255&class=Receiver&p=i is good down low, but gets muddy when I turn it up louder. 50 watt per channel.
This:
http://www.parts-express.com/pe/showdetl.cfm?Partnumber=310-2046 15 watt a channel amp is disgusting! Boring, flat, dead, not separation of music. NOTE: The 40 W/Ch does much better. It's listenable, but the "WOW" is lacking from the BGs.
4 generations earlier of this:
http://onkyousa.com/model.cfm?m=TX-NR509&class=Receiver&p=i sounds excellent and really no different than the Sonos amp at similar volume levels.
But this: Provided the most out of the speakers at every volume level.
http://signalpathint.com/index.php/decco/the-decco.html 50 watt per channel with the Sonos ZP90 (same thing as the ZP120 but w/out the amp section).
I've listened to these different pieces of gear I don't know how many times on these speakers. Many many many. I've used different sources as well. An iPod, a Zune, a cable box, a CD player, a Rhapsody. I've critically challenged myself to NOT hear any sort of difference. But there is.
Here's something I found funny.....
I have those BGs on an A/B switch. This one right here:
http://www.parts-express.com/1/1/8872-dayton-audio-iws-ab-wall-a-b-speaker-switch.html . This is so that I can switch the music from my master bedroom into the master bath and allow people to sleep. Side A is the BG PD-6Ci, Side B is a Jamo dual voice coil indoor/outdoor speaker
http://www.jamo.com/eu-en/products/i-o-6-52dvca2-description/ . Guess what!!!!!????? No difference in sound quality between anything I play on it.
I have done this amp switching on a great many of different types of speakers. I have these in our showroom:
http://www.phasetech.com/products.html?product_id=CI-7.3-QM and there's a significant change in sound between the amps with the same results like with the BG. These Phase Techs are spectacular sounding speakers, but gross with the Pyle amp. I've also played around with these and a Nuvo Simplese system like what I linked you earlier. Does not sound like it's supposed to. but, on simpler speakers.... all about the same accept for when they get really loud things can get gross with the Pyle amp.
Here are some more tests....
Right now, in front of my at my PC I have 2 pair of speakers not 2 feat away.
- Jamo C 601 and Sunfire CRM-2
http://www.jamo.com/eu-en/products/c-601-description/
http://sunfire.com/productdetail.asp?id=24
That's a $438 pair of speakers and a $1600 pair. Both bookshelves. With the little Pyle amp, they both sound great (I like the way cheaper little Jamos better for this purpose, BTW). Very good! This is with a mini-jack to rca cable run from my PC into the Pyle. But that's at 2 feet away from my head and at very low volumes. I took them both into my 12-19 sitting room and tried them out. The Sunfire got pretty gross (blaring) as I had to turn the volume up, the Jamos did fine up until I got to what I would consider a movie volume, then it was really harsh.
I then put them on the Decco and even at low volumes I was getting real detail out of the speakers. As the volume increased I didn't have that urge to wince, like with the little Dayton amp.
Once, about 4 years ago, I had a large set of BG ribbons in for demo
http://bgcorp.com/PDFs/FS-520 Radia Product sheet .pdf. I used a 125 watt Sony receiver to try and power them. Uh.... no. They struggled mightily. I mean, no life in these things. I switched over to a Parasound 2125 (same rated watts, BTW) and the speakers came to life. Granted, I still didn't care for them all that much, but they at least put out some sound.
I have a ton of examples where switching out a receiver or amp to upgrade or down made a difference in the sound quality of a system. A lot of receivers are the same in their given price points, as are a lot of amps (it all depends on the "manufacturer") but putting more real power into a speaker usually only results in better sound.
That's why when you said that you can put 15 watts in the RF7II and it will be fine I thought to speak up. Every amp/receiver/etc. does not sound the same with every speaker. Everything has it's optimal balance for what it minimally needs to sound it's best in a given environment. An OK pair of speakers will not sound great with a great amp, but a great pair of speakers can sound bad with an OK amp.
I hope that I have clarified myself better. If not, I'll be happy to provide more real life example where I've encountered real world differences in performance between products.
