Walker Audio high def links?

I had both the Hi-Def links and Ultimate Hi-Def links, and while they both worked very well to my ears, I recently discovered Argent Audio BOBs, which, to my ears at least, add a little more realism and detail to the sound than the Walkers. And they're significantly cheaper than the Ultimate Hi-Defs. And not as fragile. Like the Walkers, they don't work in every system, but Argent offers a 30-day warranty. Argent's phone number is (785) 331-4123. I'm in no way affiliated with the company--just a very happy customer.

Yeah Ric's BOB module didn't work in my systems either.

Walker HDL and Ultimate HDL both worked wonders on my Sound-Lab U-1's. After I switched to Dali Megaline the difference was slight, but still worthwhile.

I have the BOB modules here too. I tried them only on my Dali's as Sound-Labs had been sold before BOB's arrived. The BOB's did not work with the Dali, unknown what they might have done for U-1's.

thanks for all opinions and thoughts
