KRK ERGO

I A/B'd them by listening with the machine indicating a 95% room knowledge in the on position and then removing the machine and putting my interconnects back in place. Absolutely no difference with the exception of a decrease in gain with the Ergo in place.

Perhaps that could mean that your room is already well treated and/or acoustically correct?

So there is also no difference in the sound of the ergo and and your $5000 CD player? That is what you are saying, correct?

That is correct Robr45

I added a Martin Logan Dynamo subwoofer to my system today and had to recalibrate the Ergo. I did it twice, so I feel more comfortable with the process now.

A few thoughts;

1. The built in crossover+ room correction makes dialing in a subwoofer easy! Integration is well beyond what you could do by ear.

2. The software is buggy for sure (MAC for me) The biggest issue is when you try and over-write previous settings which has been noted in this thread. I found today that the "time-out" when deleting happens only if the calibrate button is pushed in. The ergo wants you to hit that button after memory has been cleared. If the calibration button is not depressed the old room will be overwritten in a few seconds. This is a work around for something that should have been fixed a long time ago.

3. Mic position is important and you need to follow the directions for focus, and specific positions 1-4. I missed position two and went to three the first time around and the sound was awful. Even though I really screwed up the Ergo thought it had 92% knowledge. After following mic positions focus and then 1-4 according to the included chart the sound was seamless.

So now I am using this thing for a firewire dac, room correction, preamplifier and line level XO for the sub. (Speakers crossed at 55hz- the integration is to good to be true)

Incredible value at $499 IMO.

This thing also has 24/96 ADC on board as well. Hoping to test that soon with my analog rig.
