The Duelund-Altec Project: DCA16GA vs DCA20GA for the Altec 804A 16-Ohm compression drivers?


I've been immensely enjoying listening to the "Stokowski" Altec's with the breadboard Duelund CAST tinned-copper crossovers. I haven't really been in any hurry to make changes to anything with the crossovers, which is a good sign that everything is coming together in a synergistic fashion musically and sonically. I've wired the breadboard versions of the... Read More »

High Fidelity: Is hifi system voicing a matter of taste? Part 1.


When I say “HiFi system voicing” you might wonder what I’m referring to. Basically, I’m referring to what any given hifi system sounds like in terms of its particular blend of musicality and audiophile-style sonics, or its overall sound quality. The musicality aspect of hifi performance is referring to performance on the basic elements of music in... Read More »
