your cd player-Whats on the inside?

[weald-audio]

Ever removed the top from your £1000 cd player?What is actually inside that fancy case that makes it sound the way it does? Someone once said that your listening to the power supply in your amplifier.In your cd player this is also the case.However, something has to make those digits that the laser reads into music.This is the job of the digital to Analogue Converter. U.S. digital experts Theta were the first company to market an offboard dac in the late eighties,since then a plethora have become available.7/8 years ago whilst attending a hi-fi show, we came across another new company whose digital experience had led them to develop a top class converter.Marketed to compete with Levinson, Krell,and Theta and beat them at their own game, Perpetual Technologies, had risen from the ashes of long time digital stalwarts Audio Alchemy.On first hearing the P3a, I was impressed.Levels of detail retrival, dynamics and soundstage, were of the highest calibre.My usual cynical self, was then reminded of a wise old hi-fi guy who told me "any idiot can make a $5000 cd player sound good,the trick is to be able to do it for $1000".Well They did.The P3A was available for under $1000.Today 6 years later, this converter beats all but the elite.It doesnt end there though.A few years ago, our whizz kid modifier Dan Wright (www.modwright.com.) began upgrading these dacs.The results are wonderful, now truly sublime, non-digital reproduction, at realistic prices.Thats enough of my rantings, if you want to know more, a huge amount of positive reviews are out there in computer land.We offer a 10 day trail, with a full money back warranty(less shipping) if the Modwright Signature P3a does not enthral.Below is a breakdown of Dans work on these units, for the techies here,please feel free to mail any questions.Oh yeah the price just £795 plus £20 DHL overnight shipping, thanks.

Are Perputual Technologies still in business - I thought they had ceased trading two or three years ago - the reviews on the web on this item are all from around 2001?
