I own a pair of recently manufactured QUARTETTES with all of the possible upgrades available. If you visit VanL SPEAKERWORKS, don't be put off by the somewhat disarrayed appearance of the place. John is a genius speaker designer, but somewhat of a disorderly shopkeeper. Be that as it may, his primary current speaker design outpreforms anything I've heard unless you go into the "stratophere" costing products. Even then, there is nothing that creates a soundstage like the QUARTETTES. Totally 3 dimensional. These are big monitor speakers. Approximately 25" in height. Beautiful cabinets but limited finishes. They need good stands. His patented "AMBIENCE RECOVERY CIRCUITRY" is the secret to the whole thing. For the price he is asking, there is absolutely NOTHING that even comes close; - - and I've been in the evolutionary audio business since the 50's.
