    I asked you a few times what speakers you'd be using with this but got no answer. Sda's may be a problem if that's your intention.

    The DNA 500 is basically 4 amps in one, 2 amps per channel in a bridged mode basically. I'd call Steve and ask him before hooking it up.

    DNA 500 vs. the M508.....I'll bet the farm on the McCormack....with one hand tied behind it's back. :)

    Post up some impressions when you have that puppy warmed up. BTW, what speakers are you using this with ?

    Hmmm... we will see. I have been highly impressed on what the M508 has been delivering these past few years - especially with the upgrades, so I do have some skepticism if the DNA500 will beat it. Notice I said if it will beat it - not match it sonic wise. But from everything I have read about McCormack Power Amps, they have all been positive reviews.

    I do admit that the McCormack uses lots of caps which influences me to believe it is a high performer - one cap per transistor impresses me a lot.

    I will be driving the Polk Audio SDA-SRS 1.2TL Speakers with this.

    Quote taken from page 3. But SDA is not my problem - yes, know well about the amps not having a common ground can be an issue. I can disconnect the SDA connection and use the speakers in stereo mode only until I figure out how to use the amps with SDA.

    I received an email late last night from SMc that my preamp, even if it uses common ground, should not be an issue.

    So now I feel safe continuing to hook up my McCormack Power Amp. Damn this thing is huge!!!! Not in height, or width, but in depth!!!

    If it was me, I wouldn't be satisfied disconnecting the sda cable, your essentially removing the element that makes them a great speaker.

    There is a work around, but my brain is only half functioning at the moment due to lack of coffee. Shoot F1NUT or Westmass a PM and ask them.

    Hmmmm...

    Turned on the unit for the first time this afternoon and let it warm up for an hour.

    So far - from my initial impressions of playing 30 year old + music on it for the past couple of hours - although it does sound a bit different from my Onkyo Grand Integra, I notice a bit more depth with the unit.

    No difference in detail or in layering between the 2 amp units. Bass detail is not noticed, but that may be due to the age of my music programming I am listening to.

    But I will know more when I start playing broadcast TV and more up to date music later on.

    My initial impression is not to say that this amp does sound impressive, it does. But it is not to the point to say that it is a clear winner head and shoulders over a 30 year old Onkyo Grand Integra Power Amp with the modifications I made. Right now, it looks like a photo finish between the two amps - with reasons to like both.

    These are just my initial impressions. I will know more as I play more programming later on tonight throughout the weekend.
