It seems the Belkin PureAV spades are not available anywhere.
I debated whether or not to get 6.1 or the 6.2 and I ended up going with the 6.2. I have never heard the 6.1 but I have really been tempted to buy a set just to do a side by side comparison. I have been very happy with my 6.2s. They are incredibly tall, but they sound great. For $1300, they are very, very good. I also have a set of Kudos Cardea C30 speakers (MSRP $12,000) and I think the Diva 6.2F is just as pleasing to listen to as the Kudos considering the enormous difference in price. The Kudos C30 is far better of course, but it also commands a much higher price.
I emailed Jon from TAI about the 6.1 and 6.2. He recommended the 6.2 saying that the crossover was better in the 6.2. I went with his recommendation and I'm glad I did. I can try to dig up his email if it may help in your decision with 6.1 vs 6.2, MrEastSide.
The Diva 6.2 really works well with good front end equipment. I originally had them hooked up to a Yamaha 5 channel receiver at 125W per channel. This was fine for about 7 months, but when I got into some better equipment they really started to shine. I had a Pioneer Elite SC37 for a period of time and it really wowed me with the Divas. Now I have the 6.2 paired with a B&K Reference 50 S2 and Anthem PVA7 which I think is an even better combination. For fun, I recently plugged my Rogue Cronus Magnum tube amp into the 6.2s for a weekend of 2 channel only listening and I was floored! Again, the excellent amplification was paired perfectly with the Diva 6.2 and they sounded incredible. All that being said, you really need to get good front end equipment to be able to appreciate what the Diva 6.2 is capable of. I would hope the 6.1 is similar in this regard.
I have listened to several high end speakers for hours, ranging from $2,200 Harbeth P3ESR, to $40,000 Vivid Giya G3 and $40,000 Magico Q3 at my local Hi-Fi dealer. When I return home, my Swan Diva 6.2F still puts a smile on my face.
