Thanks John!!!!!!

I thought that I read that somewhere but I just couldn't remember where.

I am developing an opinion that when you notice a difference, as bug did, by driving separate amplifiers instead of the ones in your receiver, then, what you have is a "somewhat" limited/ defective receiver. This opinon assumes that either the amplifiers are NOT linear to the extent that the distortion numbers are accurate or the power supply is limited and causing problems. Considering the sound level link that Ajax posted, bug was using only a few watts per channel, at most, for his listening. Bug really should have noticed NO difference.

Any other explanations?

Comments?

Opinions?

Of course, my comments above have the fundamental assumption that Bug really did notice a difference and was not opinioned because he knew which amplifier was which.

We do have a link somewhere on this board of a double blind test where listeners COULD NOT tell the difference between a $200 receiver and a $20,000 amplifier.

Just to be a litte more technically accurate.

LOL!!!!

rat,
That's why i believe Axiom should sell A/B switchboxes to the discerning customer.
They cost nothing to make.
Add a line leveler (volume control) to this unit and you are all set to go. As i understand it, a good friend of the person who loaned me the switchbox refuses to take the blind test b/c of 1001 excuses and reasons. Not surprising.

Here is ignorance at it's best. I am learning alot out here though.

My receiver has 8 ohm capability that I can change to 6. I purchased m60s. I wanted the M80s, but didn't have the receiver to drive it. If I purchased an amp, would that allow me to properly drive the speakers?

Also, my receiver is rated at 120 wpc. Would purchasing an amp at 100 wpc do me any good since the rating is below my receiver's watts???

Mike: actually that isn't such an ignorant question!

The short answer is that there are watts and then there are watts.

If your receiver has pre-outs you could look for an amplifier that is rated at 4 ohms (for the M80s). I think that should be an acceptable solution. By the way, what is the brand/ model of your receiver? I guess that it isn't rated for 4 ohms? My old Kenwood isn't rated for 4 ohms (at least that I can tell) but it drives the M80s just fine. I don't listen to really loud music/ HT, only about 70-80 dB. And, I wouldn't be terribly upset if my old Kenwood bit the dust because I'm in the market for some new gear.

Hope that this helps.

My receiver is a pioneer vsx-1015. There newest flagship model.

What do you mean by there are watts and then there are watts?

What I meant is that you have watts rated at 8 ohms, other ratings at 6 ohms and still other ratings at 4 ohms. For the M80s, you are interested in the ratings at 4 ohms. I noticed in the writeups that your receiver is rated at 120 watts at 8 ohms. Does your manual have any other numbers at 6 and 4 ohms?
