Digital Amps vs Solid State Amps

"I believe the digital amp technolody has a ways to go. Linn started the idea in the mid 90's "

Hello Levchappy,

The idea of switching i.e. Pulse Width Modulation, PWD power amplifiers started at about the same time as FM radio

The first commercial hi-fidelity switching amplifier was demonstarted by John Ulrick, cou-founder of Infinity Speakers, in 1974 CES Chicago. Today he is the President of Spectron Audio.

In order to judge audio compenent you really must audition it within your system and may be for some time.

In that regard, Spectron and surely some others have 30-days money back guarantee policy.

Rest is up to you.
Good Luck

Not exactly. FM was proposed first by Edwin Howard Armstrong in 1935 paper: "A Method of Reducing Disturbances in Radio Signaling by a System of Frequency Modulation"

Class D amplifier was proposed first by P.J Baxandal in 1959.

First commercial class D amplifier was designed by Gordon Edge and manufactured by Clive Sinclair in 1964 under name X-10.

Yep, and instructions enclosed as well.

"Digital Amplifiers:

Going back to the Infinity SWAMP 1 of the mid-1970s, digital amps have had a checkered history, but they seem finally to have turned the corner in terms of reliability and performance. Highly efficient and cool-running, they promise to play a bigger role in the future."

SWAMP was this Infinity amplifier developed by John Ulrick and shown at CES 1974....

Is that the same Sinclair who was involved in early computers?
'X-10'.....Hmmmm wasn't that revived by BSR with the home remote thing?
Was Sinclair involved with that TOO?

Magfan - I remember in late 70's Timex/Sinclair computer with BASIC interpreter and keypad with direct commands. Whole thing was running on Z80 Zilog processor. It had 1kB of RAM but you could extend it with external plug in module. I played fascinating game of table tennis on that thing for many hours.
