@adg101, thanks. Jumper straps were missing when I got the speakers.

Late to the discussion, but agree w/the last couple comments regarding jumpers. I tried several 5 to be exact .. (prices approximate) - AntiCable level 2.1 about $50- - an eBay audiophiles take on Dueland wire w/silver banana's, $99- - Tuneful Cables, $50- - Maze Audio reference $50- - AntiCable Signature jumpers $175- All were burned in 20-30 hours before my A/B'ing .. Hands down all the cable sounded more expansive and natural than compared to the brass straps on my 7b's.The Dueland audiophile made (brand forthcoming) were terminated w/silver solder and silver plated banana's. They were brighter, with good stage characteristics, balancing out the warmth of the Aerials, but left a huge dry gap in bass performance. The Tuneful cables performed well but were not a standout. Both version of the AntiCables offered the best overall performance, with the Signature version way outperforming all. Paul of AntiCable described to me a long search to find the right solder compound to terminate the his best wire to the spade/banana. For background .. I am running the 7b's w/a Counterpoint NPS 400 (200 wpc @ 8ohm & 400 @ 4 ohms) recently re-tubed by Sam in Michigan w updated Silver level HiFi Tuning fuses (Directly fed by Oppo 205). With burn-in time it is a SWEET combination blowing my walls out with great depth and staging. I do have to put a plug in for Bionic Wire InterConnect (Wow!) using XLR from Oppo to Counterpoint. Using Mosaic speaker cables, Shunyata everywhere (Python/Delta NR) except for a Darwin Cable Silver power cord into the amp .. replaced 1 of my Pythons nicely. |
If you look at the impedance graph of the 7B’s you’ll see they spend a lot of time where the power and current are needed from an amp, in the 3-4ohm region between 30hz to 500hz. https://www.stereophile.com/images/archivesart/A7bfig1.jpg The amp that’s needed is one that is comfortable at 2-3ohms, and one that has good current delivery. The stock DNA-1 will have no trouble, tested at: 191W into 8 ohms 352W into 4 ohms 510W into 2 ohms Yours with an even bigger transformer, is better again. And the DNA-1’s gain is very high, an input voltage of just 100mV in gives full 191w output, that and with 100kohms input impedance, this amp is begging for a good passive preamp. Cheers George |
