"Own the very best!"

Stock high-end audio gear still leaves a lot to be desired.Even ultra high end models simply fail to come close sonically to the same model which has been upgraded.

Several months ago I gave David a call to reference some questions I had about having my Denon DVD-5910 upgraded. During a lengthy conversation David thoroughly answered all of my many questions and he did it in an enthusiastic fashion. Attitude is something I put a lot of stock in when it comes to having skilled work done on anything and David had a confident and experienced tone to his informative dialogue. After hearing about my HT David suggested I have my Marantz SR9600 A/V receiver upgraded. David was not pushy but he did tell me the improvements in the performance of the SR9600 after an upgrade would be nothing short of amazing. What the heck. Let’s have a go at it, shall we?

Skip ahead to the pick up date. I’ll keep this short and focused on my SR9600 A/V receiver because there are several reviews of the upgraded DVD-5910 elsewhere which mostly mirror my experience. The difference between my stock SR9600 receiver and my upgraded SR9600 receiver was nothing short of being much more noticeable than a major component upgrade. What an unbelievable difference. I could bore you with all the audiophile descriptor terms we love to hear, but I won’t do that. I’ll just tell you the sound of my receiver after the upgrades causes me to listen to what ever is in my source components longer. Prior to having the upgrade done to my SR9600 I did not think I was straining to hear the audio dialogue in any movie. I was damn proud of how good it sounded and I had the compliments of my friends and family as reason to believe. Yeah, well, I was wrong. All it took was one minute of one movie and one audio track to make me realize how much better it sounded after the upgrade. Sharp, transparent, black, dimensional, powerful (sorry, I said I wasn’t going to do that). The longer I listened, the better I realized it was. Better in every way. Two channel audio playback was so impressive after the upgrades that it completely rid me of even considering picking up something new (and that is a good thing!). I‘ve been through a lot of gear over the last few years and I‘m glad to say I‘ll be keeping my upgraded SR9600 receiver and my upgraded Denon DVD-5910 for a long time.

Probably the best money I’ve spent to date on this “hobby”.
