I have a Firestone Fubar III amp/dac on the way, with stock opa2604 in the amp module, and lm4562 in DAC. I'm hoping I could get some recommendations to upgrade the stock opamp.

 

* Power - 24V 0.5A Auto-switching

 

This will be my first amp/dac unit, and l will be using it with Denon D2000, through mac mini.

I'm looking to tame the somewhat strident highs of D2k, bring out the mids, improve the soundstage, and harness the bass (i.e. increase speed and impact).

 

My only consideration so far is the dual opa627 combined on a single PCB (note: this has been tested and recommended/sold by "audiophileproducts.com" -- North American distributor of Firestone audio), possibly with a class A biased mod; although not sure whether this will yield any perceivable improvement with my modest setup. From I understand, it seems to be an improvement for Matrix M-Stage.

 

Please feel free to share any related experience or info...thanks smily_headphones1.gif
