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

only if country can be organized that Pass doesn't need to work more and work anything else than in very moment .

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.
