It looks like a beast. I would love to hear one. I may have to stop by the Needle Doctor here in town and give one a listen.

It's none too cheap at $4500. I like the ESS Sabre 9018 DAC and the XMOS asynchronous USB interface. The amp sounds suspiciously like a Class D Audio, say a pair of bridged "SIMON SDS-OEM" modules, HERE. (Class D Audio sells the module to DIY'ers but, according to Tom at CDA, provides no information online because of an agreement with an OEM who uses the modules.)

Like the casework, defeatable 80hz high pass, 12AU7's however the volume knob stinks and 440w/ch but the thing only weighs 28lbs (class D stench). Would have to sound totally out of this world for me to even consider this especially at $4,500 bucks retail.

Who cares if it a class d. 770wpc, high current, 2 tubes, with a preamp and state of the art Sabre DAC all in one chassis! I agree it is pricey but for an all in one with that kind of power, it is a nice piece of kit! I have heard Peach Tree gear and it sounds great.

You make a good point but I'm very biased against high power class D at the moment. I'd have to hear it with some speakers that actually crave that kind of power and see how the thing holds up.

I actually did come across this a couple days ago. Beautiful piece of equipment! Can someone please explain what the difference is between the amp classes?

Hi, Landy,

A fairly succinct explanation can be found HERE at hifivision. This item is technically helpful but quite dismissive of class D amps for hifi application. However given the current state of the art, the statement that class D amps, the assertion that "Class D amplifiers are models of efficiency but with a loss of detail and fidelity" should be considered no longer true. Today there are many high-end brands that offer class D amplifiers. On the other hand, there as still lots of people who say they don't like class D sound.

A more thorough and technical explanation HERE at Wikipedia -- scroll down for class D which also has its own Wiki item, HERE.

Class D has come a long way in the past decade. It started gaining traction in the portable PA market due to its low poundage/wattage factor. In that market, amps used to start at 40# and could easily be double that. Put two of them in a rack and it wasn't really very portable. That new little NAD D 3020 integrated amp is packed with features, only weighs 3#, cost $500 and has been receiving glowing reviews. 30 WPC from a package that will fit comfortably in a briefcase! And Peach Tree is on a roll, I doubt they would take a chance with something that wasn't pretty stellar.

Yes, Class D has come a long way. I love the sound of many Class D amps. They are definitely on par with Class A/B amps. Many manufacturers are producing high end Class D gear. Give a listen to the Nuforce Model 9se monoblocks. They are very tube like, detailed and dynamic. I contemplated buying a pair instead of my Pass amp. What's nice about Class D is that you can get that air, transparency and 3D like presentation that high end amps give for a fraction of the cost.
