I'm loving what this little amp has done for the sound. The control that it has over the speakers is just amazing. The first thing that struck me was the clarity and slam on all instruments. The music feels tight and clear, with nice soundstage depth and width. The scale of the sound is huge, and I'm enjoying listening to my CD collection again.
I received my GaN amp on Monday. After letting it stay powered up for the entire day, I tried it with some music in the late evening. I was stunned at how great it sounds. I always thought the CDA 254 kit amps I built sounded ridiculously good for what they are, the GaN amp goes way beyond what the CDA amps can do.
I think everybody should have at least one, just to realize how stupid equipment prices have become. This amp needs to bow before no one in my opinion, it really does sound that good.
You should really be proud of what this amp can do.
no flat earth here. As I have been listening I observed several attributes, one of wjhich was that these babies showed how excellent they are with the best recordings, so I have purchased at least 20 more albums to critique them and enjoy them.
Treble. Sweet, extended, fast, as the amplifier has matured all these characteristics have improved, just with better separation, extension and placement in space. Class D can sound thin and gritty, none of that here, even poor recorded recodrs remain listenable.
Midrange. Male and female voices are a true strength, even friends say the vocalists are in my room, nothing can be better than that. What is also stunnig is the tone, tonal neutrality and space. The space around instruments and people has probably been the biggest change as the amplifier is used. More width, more depth, the speakers are really transparent now, everything comes in space 10ft high, wider than each speaker and as deep as tey are in the room.
Bass. Everything is fast, very fast. Class D can sound thin in the bass, which is why I could not keep the Wyred4Sound, even the top of the line monoblocks, could not compete here. A small improvement in the bass in space is observed as it has matured, and everything just seems more relaxed and open.
After so many huge and heavy beasts over the years, Parasound, Quad, Emotiva, Carver, Rotel, Meridian, Wyred4Sound, Nuprime, Odyssey, NAD, Cary, Linn, Starke and Lexicon, I wanted to find a class D with the sonics of the best class A/B, which I have no desire to lift anymore, so I needed to dethrone the Parasound and Nuprime, and eventually I have.
So how could it be improved? An exotic case, but that is nit picking. Only bass weight and consistency are unknown. Bass weight seems very good but I don't have a great lternative to test this, the Nuprime and Starke Audio are class D too, and it is better than they are. Consistency I will checj once I receive another order when I can compare the build consistency between multiple builds.
Yes, this is a rave review, and in the context of my goals very successful. Can I do better, with more money and weight, I can think of Parasound JC5 or JC1+, my favorite amps so far, only more thump and fullness, but this little baby is getting closer at a fraction of the cost, and maybe the bigger GAN amplifier can reach the levels of the JC1+. I await the dream.
Have been enjoying SDS-470 for over a month now. Amp is a little jewel. Build quality is very impressive with the 12 inch x 12 inch x 3 inch block weighing in at over 22 lbs. Metal work is very nice though simple, almost minimalist, which I like. Spoke with designer of product about using the amp to power two 12 inch 4 ohm subs, and a pair of two way satellites. Tom claimed there should be no problem driving them all with this amp. He was spot on. The amp makes all the speakers sing like never before.Treble and midrange are crystal clear with pinpoint focus. Amp is dead quiet and when called for the dynamics are stellar. Soft passages are delicate and detailed and loud passages are presented with great speed and authority. Bass is clean with lots of punch and better integrated with sats than ever before. Pace, detail, soundstage and depth are better than I have ever heard on my system, by a very considerable amount. I replaced two 60 watt, cryogenically treated monoblock tube amps with premiums tube powering the 8 ohm sats and two 250 watt ss monoblock 12 inch 4 ohm subs with this one amp and it handily outperforms them all. The more I listen to this amp the more impressed I am with it. A side note:The first amp I received lost the left channel after two weeks. I contacted Tom and he promptly sent out a replacement and arranged for pickup of the defective amp. The way that this situation was handled speaks volumes to what kind of company Class D Audio is. The owner was first off all shocked that the amp went south, but really was concerned and apologetic for the inconvenience. As a bonus he threw in a little tweek on the replacement amp at no charge. Overall some of the best customer service I have ever experienced. I am one happy camper with this amp. Highly recommended, without hesitation.
The Class D Audio SDS-250C is cut from the same fabric as the rest of the SDS line. It is quiet, clean and deals well with a variety of loudspeakers. The gain controls are a god-send for powering a surround sound system or satellite/subwoofer combination. The incorporation of XLR and RCA inputs increases the versatility of the amplifier. Highly recommended.
