$950/pr in Cherry or Maple; $450/pr nude; $25 for custom jumpers


Ultimately, speaker manufacturers should install impedance-matching autoformers in their crossovers if design parameters enforce the use of 4-ohm drivers and even lower impedance sags. Such idealism of course is not for sale yet. Paul Speltz originally envisioned the Zeros as a solution for OTL amps. Customer feedback and personal experiments subsequently suggested that the Zeros can also benefit other amp designs. I cannot disagree. If I had to mate the JAS Audio Bravo 2.3 to the Mark & Daniels for example, I'd do it with the Zeros, hands down, no reasons given why I pursued such a peculiar match to begin with. If I sound less than 100% committed, it's because proper matching of speakers and amplifiers should be done directly, no mediating devices necessary. That it often isn't says as much about poor audiophile habits as it does about modern speaker manufacture which cares little about how hard it makes amplifiers work because "power is cheap". None of these various arguments and counter comments take away from the fact that the Zeros work exactly as advertised. Whether you should like a pair depends squarely on how well you've managed your amplifier/speaker interface and whether you've obeyed good sense and sensibility. With many tube amps being less than sensible where optimal speaker control is concerned, the Zeros can level the playing field in your favor...

Σιγά τα ωά...

Κάτι τέτοιο έχει βάλει η McIntosh στους ενισχυτές της εδώ και χρόνια.

Mα η όλη μαγκιά ενός OTL ενισχυτή είναι ότι ΔΕΝ χρησιμοποιεί μετασχηματιστή στην έξοδο.
Αν κάποιος ενισχυτής έχει πρόβλημα να οδηγήσει ικανοποιητικά ένα ηχείο, απλώς δεν τον χρησιμοποιείς.
Υπάρχει και η λύση του Super Charger Amplifier της MF, τελικού τρανσιστοράτου ενισχυτή που λειτουργεί με μικρό κέρδος τάσης αλλά με υψηλό κέρδος ρεύματος (ενεργος απομονωτής "buffer") .
