Buyer to pay postage. Further information: Bought this maybe 2 years ago. Purchased because it is a "direct" design that doesn't use a conventional DAC chip. Instead it converts the digital PCM to an analogue PWM signal that is then used to directly drive a class D output stage. This method works really well but it has a certain sound to it, less smooth and more lively, that works for some and not for others. It does have quite a good power stage, it was surprising to hear it do so well on Terry's VA speakers, you know, since it's all of 3 kgs. Comes with remote and no instructions (since that's the way it came to me). The remote only has about 4 functions so even if you just keep pushing buttons randomly you will still manage an acceptable level of control over the unit. Also, I seem to have taken the pictures of the amp with the wrong remote next to it. I do have the right remote and you'll see it if you look at the next FS post I put up, I'll put in a little more effort to get the remotes right before I do any posting. Promise! This unit has the optional USB card installed. I don't have the original box but this puppy's small and light-ish so postage won't be too difficult. Available new here. https://www.ebay.com.au/itm/303497865760 Photos:
Buyer to pay postage. Further information: Another "Power DAC" or "Direct Digital Amp" that doesn't contain a conventional DAC chip. It converts a digital PCM signal to an analogue PWM signal and uses that to power a class D amp directly. This one sounds much smoother than others I've heard, a little too smooth for my tastes actually. I expect it would pair well with bright-ish speakers. Comes with remote (not the one in the pic, that's the wrong one, my bad, it will ship with the correct one) and original box which contains the original cable pack (power, coax and usb).

Further information: I have owned this amp for approximately 4 years and have rarely used it as I have always had too many other amps to mess with. I have just taken it out of its box and it it working really nicely. Having recently purchased an integrated amp for my work flat and I have a big Krell for home so the Halcro is not needed. As I live in NE Victoria or Alpine N.S.W (when I am at work) I can drop this off at TNT in Albury for freighting. (Freight to be paid by purchaser) It is way too heavy for posting. I still have all the original packing (double boxed) Here are the specs. Power Output: 400W RMS continuous into 4 Ohms Distortion THD: <0.007% at 1kHz at all powers up to 400W into 4 Ohms, <0.03% at 7kHz at all powers up to 400W Unbalanced and Balanced Voltage Inputs Mains Voltage: 100 – 120VAC or 190 – 250VAC Remote trigger switch between On & Standby Command Functions: Switch between On & Standby Ability to inhibit individual amplifier modules Amplifier module will indicate Over Temperature condition Halcro Reliability Assurance Service Dimensions Weight: 49.8lb or 21.1 kg Height: 7 inches or 169mm Width: 17 inches or 438mm Depth: 16 inches or 410mm Sorry for the crappy images, just some quick pics with the phone Photos: Advertisements without photos of the actual item will not be approved.
Almost 3 years ago now I wrote my first 'real' review for SNA. https://www.stereo.net.au/reviews/classe-sigma-2200i-integrated-amplifier And I liked the amp that Marc sent me to review. I liked it a lot. So much in fact that when the opportunity came up to buy one for a 'measly' $3500, I took it. That ebay transaction fell through and my money was refunded, which disappointed me no end , so I was forced to soldier on. With the news that Classe was closing down I was hit hard, no more Classe meant that when I was ready for it there might not be a Sigma 2200i ready for me. Then came the news that Classe was being bought, followed by the news that the Sigma range was probably not going to be continued, which made me happy initially but then just as sad. It looked like there would be no Sigma 2200i for me. So I was pretty damn happy when one popped up on SNA for the same price I was willing to pay via ebay. After all, this is the integrated amp that sits at number one on my list of favourite all time amplifiers. So, to celebrate my acquiring of what is highly likely to be my end game integrated amp * I've decided to release the scores I awarded it in my initial review. I didn't put them in to the initial write up as that sort of thing is just not done in official reviews. But, just because the scores I give to each and every amp I review may never see the light of day in any official capacity doesn't mean I don't evaluate and award them in the first place. They just stay on my sheet of notes. However now that I'm an owner it's less official and more personal, so those numbers are about to be set free. I'm going to see if I can copy the original review and then add in the numbers in the next post. Hope this works. * Yeah I know, I didn't think it would ever happen either.
