These very speakers are now the property of my listening buddy JW and they’re set up in my listening room for extended evaluation. They wil be compared to Magnepan MG3.6R and MG20.7. An extended review, comparing 3 sets of Duetta Signature (including a refurbished set) can be found here:

…but this is how original Duetta Signatures usually look
And this is how the refurbished Duetta Signature looks – much better don’t you agree? You only need to be careful with the fully exposed ribbons…
The second revision of the original Duetta was a visual and electrical redesign, the front lip of the Duetta cover was removed to give a tidier appearance, and sturdy aluminium feet were added. The crossover was redesigned to enhance the high frequency response, along with the addition of a three position mid/tweeter level switch.
According to reviewers the signature greatly improved upon the bass performance of the Duetta II and also had a clearer high frequencies and was less prone to sounding bass heavy.
When it was released the Signature offered exceptional performance to the lucky few who could afford it along with the necessary amplification.
It likes to be well clear of walls 3-4 feet from the back wall, and at least 1-2 feet from the side walls helps imaging greatly.
