Nope, never had any inclination to change or upgrade the Signature IIIs. Those are the same speakers I’ve had all along for sure. They replaced a pair of Martin Logan Aries-i speakers. That was one of the best moves I’ve ever made in my trek down the audio trail.
The original price with the finish on these Signature III’s was around $5,000. I bought mine used for $2100.00 plus shipping close to fifteen years ago.
So, let’s consider that someone bought a pair of Signature III’s today for $2000.00 (they can be had for much less), then placed $6000.00 worth of the new Omega *Plus* Mats on them as I have. I would challenge you to find a speaker that retails for $8,000 that could compete with what I have going. It wouldn’t even be close.
One of my favorite speakers is the Harbeth 40.2’s. They are one of the most tonally correct speakers on the planet. The Harbeth’s are absolutely emotionally and musically involving. They sell for around $16,000, maybe more depending upon the finish. That’s twice the money that would be invested in the totals above ... and the results I’ve obtained are far better than what I’ve ever heard from the Harbeths. And don’t take this as a slam to the Harbeths. They are an outstanding speaker.
Imagine all of the tonality of the Harbeth 40.2’s, plus better highs, better bass, and more "see-through" clarity. That will give you an inkling of what I’ve got going on here.
Too bad you don’t live within driving distance. I’d love for you to sit down for a demo. For sure ... I’d have to pry your jaws off of the floor. *lol*
