APOGEE: Their Diva speaker

The Diva was Apogee’s most expensive ribbon speaker when it was released in 1988. Nearly as large as the original Full Range it was a 3-way system, slightly over 6 feet tall with a very large trapezoidal bass panel, a 3 element aluminium midrange ribbon and a tweeter made from a single strip of aluminium […]

Dynaudio Special Forty “These 40th anniversary Dynaudios are classic in looks but cutting edge in ability.” Tested at £2,500

What HiFi? write …. We have a confession. Our first impression of Dynaudio’s 40th anniversary speaker is more one of mild disappointment than anything else. It’s not that there is a lot wrong with the Special Forty – it’s just the design seem a little too familiar. Dynaudio has made any number of two-way standmounters, of […]

PS Audio: Building the high-end brand

  Paul McGowan writes: The high-end doesn’t really have a brand or a neat way to bundle up its concept and present the package to someone interested. That’s a problem.  For the process of engaging a new community of high-end customers, high-end as a concept must be packaged and easily grasped by a potential customer.  […]

Bristol Show: Says one visitor – “It will come as no surprise then, that for me, PMC stole the entire show — I kept returning to that room”

Mark EJ (pfm member) writes: PMC: Since first hearing an early pair of LB1s with a 52/135s fed by a Roksan CD player (shutting down the 135s every 15 mins) at a Heathrow show in the early 90s, I’ve been conscious that PMC succeed (to my ears) in quite a lot of what they attempt, […]

PS Audio: Solid state vs. fields

Paul McGowan writes: This post will most likely stand the hair up on the back of EE necks because it’ll be riddled with inaccuracies I will use to make a point about why devices sound differently in audio circuits.

PS Audio: How may I serve you?

Paul McGowan writes:  If for some reason your power amplifier puts DC into your loudspeaker you’ll wind up letting the magic blue smoke out and killing your loudspeaker.  ”Magic blue” smoke is engineering humor: it’s what we jokingly say when a component blows up and smoke spews from its innards – “oops, we let the […]

PS Audio: High voltage and linearity

Paul McGowan writes: In yesterday’s post we covered the fundamental differences between tubes and transistors and one of those we’re interested in is linearity. Tubes and transistors are only partially linear devices – which means they will not always faithfully reproduce a larger version of the input signal on their outputs. In our example yesterday […]

Confessions of a Part-Time Audiophile / CAF 2013: High Water Sound (updated!)

“I’ve written many times about the audio wizardry of High Water Sound‘s Jeff Catalano. Ask around — this is one of the few rooms you can expect to hear something non-scripted. Something off the wall.
