Impedance Matching Question

Polk Audio RTi A3 is on closeout for $240/pr, so not much more than the cable.

Yeah definitely the money shot is for the speakers, how come we don’t get those kind of deal down here in Oz, it really ****** me off. Enjoy!

I'm sure if you look around you find an iTube around $200 soon enough, 

Nice find, now that looks good I think, seems to be tube input with ss output great combo to get low output impedance and high input impedance.
100k input impedance and 1ohm!!!! output impedance, can be used as a unity gain buffer, or preamp with gain and volume control.

" 8 DIP switches that allow us to select the gain (0dB/6dB) and whether using it as a pre-amp or as a buffer with the help of a flat screwdriver (like the one included)."

Thanks George for the iTube comments.

astelmaszek - initially I thought the iTube2 at $399 was more than I wanted to spend, however after finding a deal on the iTube for $239 shipping included, I’m thinking that’s just a little more than the Burson cable at $200 and the iTube has more capabilities than a cable. This same authorized dealer is also offering the iTube2 for $279 shipping included, so I ordered one. I’m thinking I’ll just have fun trying it in various places of my systems, and then always have a good way to use any amp with the VTL if I so desire. Thanks for your recommendation of the iTube.

I've had mine for ~2 months and still delighted. Hope you are too, but use good interconnects, not the included ~6" ones.

Also agree about the miracle box thing😀. It serves the music so well..
