I can't say I was aware of your tests Mojo. I was well aware of the extensive tests Chess had performed though. If you can point me to your post I would be more than willing to give it a read.




Here is a repeat of my "blind testing" post from two days ago.

Some of you will like me for this and others will hate me but in the interest of advancing knowledge on this subject I have decided to post this.

I decided to blind test my wife's plastic, dinky Sony boombox with my Denon. Here are the specs:

Sony CFD-Z130: 2.3W + 2.3W into 3.2 Ohms at 10% harmonic distortion.

Denon AVR-2105: 90W + 90W into 8 Ohms at 0.08% THD from 20 Hz to 20 Khz; 125W + 125W into 4 Ohms at 0.7% THD at 1 KHz; dynamic power of 170W/channel into 4 Ohms.

For the Denon, I used my Sony with optical out as the CD source. The boombox has its own CD player.

I put on some Poncho Sanchez and adjusted the gains for 75 dB SPL. By the way, 75 dB in my room requires less than a watt per side. After I had everything adjusted I called in my wife, son and daughter and let them listen to the Denon for 2 minutes and the Sony for two minutes. Then I sent them back out and covered everything up. To make a long story short, we tested 12 times for a minute each time and I had them write down their answers each time. The test was painful as I had to keep changing the leads. Here is the raw data. The first field indicates the amp under test and the last three fields the selections they made:

1. S, D, D, S
2. S, S, D, S
3. S, D, S, S
4. D, D, D, S
5. D, D, S, D
6. D, D, D, S
7. D, S, S, S
8. S, S, S, D
9. S, S, S, S
10. S, D, S, S
11. D, S, D, D
12. D, S, S, D

Out of 36 possible trials, 21 turned up the correct response. That's not much different than guessing heads or tails.

I haven't revealed the results to my wife because if I do, she won't authorize an A1400-8 .

Understood. Having fun or not, I thought your comment was a pretty good summary of where the thread was heading so I figured that was a good post to respond to.

I agree completely with your opinion -- I'm just less convinced than some that a typical AVR has enough juice to cleanly drive our equipment to the levels we desire.

I realize this puts me right in the demographic crosshairs for an amplifier I can't afford

I'm just glad my 70wpc receiver is driving M22s in a small living room with the assistance of my ep500.

I still want to know when the Pre/Pro is coming out. That A1400 is going to look silly on my rack with a different brand processor, although the new Denon is looking promising – other than the price.

Common Ian, don’t leave us hanging…..

mdrew,

The matching Pre/Pro is still a ways out there though we have started on it. I think we are looking at mid 2008 right now. If you go with black the A1400-8 should disappear into that rack (it is only 4" tall).

Now this is some very interesting news My RV-8 does a fantastic job but lacks HDMI support. With this news, I may just be patient until next year before any upgrades are done.

Thanks for the information Ian.

Sweet.... I didn't realize it was going to come in black. If you need help with the design from a user perspective, I may be able to provide some input (seeing how fast I'm going through these HDMI recievers)

Yes, please feel free to use us as a resource when making decisions about the pre-pro.

By the way, when I put the preorder for the amplifier in my shopping cart, it says "Pre-Purchase Axiom Pre-Amp" in the item description. Someone may want to change that to "Amp" and not "Pre-Amp." I'm sure people will know what they're ordering, but hey, it still weirds me out.

Ian/Amie/Alan,

Are there any specs on this amp to share yet? If not, will there be before the end of pre-order date?
