Damn would be nice .....:D

Pass Labsí engineer Wayne Colburn insisted that the name of their latest amplifier, the Xs, was not a pun. He spent over an hour detailing the 3-year design project that culminated in the company's $85,000/pair, solid-state, two-chassis-per-channel, class-A amplifier. Leaning on the 4.5-foot stack of the amplifier's stereo configuration, Wayne spoke about how the design was based on the results of an examination of transfer characteristics of a diverse set of gain devices, including tubes and SITs (silicon-carbide devices that are exclusive, we believe, to Pass Labs for use in audio). The output stage was designed to reproduce the transfer characteristics preferred by a panel of listeners, who lived with a variety of different output stages for a lengthy period of time.


Each Xs channel has two chassis, one for the power supply and the other for signal amplification. The amplifier acts as a voltage source, and is rated at 300W into 8 ohms, 600W into 4 ohms, and 1200W into 2 ohms. It is biased to ensure make certain that the amplifier remains in class-A mode into all loads. Each channel has 122 output devices with a total rating of 10kW, and the extensive heatsinking allows the Xs 300 to deliver 2kW into a load "all day long."


:eek:

:worship:

At that power, in class A, who needs central heating?! :D

Pass for president!!!.

hahahahahah

Nelson, you are the devil, better not let greenpeace get a hold of this :cheeky: that man better pray there isnt an earthquake, he could be crushed under the weight of a stereo amplifier. normally when people talk about the 'weight of sound' i dont think they have this in mind.

122 devices per channel? wow

Those would drive the Ion Cloud really well.

Just matching output devices is a huge task.

wayne 16th January 2012 10:49 PM

Not that hard to match it is only 112 transistors not 122. I may have slipped with all that talking at a show.

a.wayne 16th January 2012 11:04 PM

Errr OK, much easier now .... :D

I'm surprised you guys would attempt to market your own speakers along side the amplifiers, usually a no,no, as it usually chuffs off Speaker manufacturers and stop them from using Your products when promoting.

No problem, you think an 8% discount is open for negotiation ?

labjr 16th January 2012 11:06 PM

There's pictures on the passlabs website. Looks like Neutrik Powercon 32 Amp power connectors. Nice stuff.
