Red Dragon's new S500 Class D Amp

Hi 1extreme,

Can you detail what other components and speakers you have in your system that you would pair with the Red Dragon S500? The reason I ask is I have the older Red Dragon M1000 Mk 1 monoblocks powering a pair of Ohm Walsh MicroTall SE speakers BUT I have a predominantly tube front end. A tube dac and with a tube preamp. The tubes along with the Red Dragon monoblocks is a very heavenly sounding combination to me.

Best of luck with the search. I've spoken to Ryan at RedDragon and he is a real nice guy.

My current speakers are Infinity Kappa 8's.
I am powering them with an Adcom GFA-565SE (250w @ 8ohms)
I have a DAC / Preamp combined in an Emotiva Stealth DC-1.
All my source is streaming.

I also would like to introduce a tube preamp into the chain. My interest in the S500 was to see if it out performed the Adcom and if so I would replace the Adcom. OR if the amps are compatible I would bi-amp them horizontally, but the gain of the Adcom is 27dB while the gain of the S500 is 26dB. Also, S500 has higher output at 4ohms and 2ohms than the Adcom.

I purchased an S500 a few weeks ago, but haven't put too many miles on it yet. I am building a second system (music only, 2ch) that isn't ready yet, but I inserted the S500 into my main HT/music hybrid system for a couple of weeks of music listening.

Here are the associated components:
Primare SP31.7 processor (in analog "bypass" mode)
Yamaha CDR-HD1300 (a very early hard disk based music server, used as a transport)
Wyred-4-Sound DAC2
Totem Mite-T loudspeakers

The Red Dragon S500 temporarily replaced a Sherbourn 5/1500A (5 Class A/B monoblocks in a single chassis design). I think the S500 sounds great. It is dynamic, very quiet, and a remarkably wide soundstage. A common criticism of Class-D amps, particularly earlier ones, is that they are bright and "brittle" but the S500 is neither of these things. Compared to the Sherbourn, it is quicker and more musical, but a little less "authoritative" sounding (the Sherbourn is a bit dark). I think the S500 is a more neutral amp than the Sherbourn. The lower gain (26db vs about 30db for the Sherbourn) meant my pre/pro had to work a bit harder. It runs very cool, something I was looking for since my 2nd system's room will not tolerate a Class A/AB space heater, and it amazes me that such a small amp could produce so much clean power and sound so good doing so. Overall I am very impressed with the S500 so far.

I haven't heard the PASCAL amp module making class D power but I have never loved the sound of the usual class D suspects. I have to say this one looks intriguing and I like it when an amp doubles down into 4 Ohm (like good ole class A). The 12Lb heft also ads credibility. The one reviewer didn't exactly go overboard with compliments, so we will have to see if the small size amp big power output is a winner or just another almost. Class D does do a great job with power hungry subs, again, lets see if it can go up the sound spectrum.
It is going to take an awful lot to take tube amps from me so perhaps I am not the best judge.

OR if the amps are compatible I would bi-amp them horizontally, but the gain of the Adcom is 27dB while the gain of the S500 is 26dB. Also, S500 has higher output at 4ohms and 2ohms than the Adcom....

The 1dB difference in gain might not be an issue at all. It's a difference no doubt but it might not show up in the playback. You could use the S500 to drive the highs & mid & your Adcom to drive the bass since the Adcom has a heftier sound.

Your comment of "Also, S500 has higher output at 4ohms and 2ohms than the Adcom" has me confused.
You realize that's not the output impedance of the S500 amp? It's the ability of the amp to drive an 8ohm & 4ohm speaker load with a minimum speaker load of 2 ohms. You might already know this & just mis-wrote the above line but i thought I'd clarify. Thanks.
