Try Tellurium Q Blue. Entry level for about $120. Am using them with my Maggie 3.6's and replaced $400 MIT and $1000 Goetz Alpha Core. These cables are very transparent with tons of resolution. Also great micro and macro dynamics
Nice system...I have often seen people use Transparent Reference cables with Krell (including D'Agostino himself). I would suggest if you buy second hand older Tranparent Reference cables (i mean pre the MM1 or MM2 series)...which are cheaper...they are excellent. I have much preferred them to the new Transparent Supers...YMMV.
I would try the Mapleshade Double Helix speaker cables with Plus upgrade. $440/pair with 30-day trial period. I use them with my Mystere tube preamp, CODA Technologies SS amplifier, Rega turntable and Totem Sttaf speakers. I think they sound great after the break-in period is complete.
i had an s300i for about a year when they were released. tried a few speaker cables and came away feeling the acoustic zen santori shotguns/double barrels sounded the best using my aerial 7b's. (didn't try the reg/single line santori's)
not sure what your toyota is worth but if you find a pair of santori's that aren't "mint" (outside mesh chews up easily)....they can be had for well south of $500 depending on length. there's a pair listed now for $350.
kept them when i switched to a levinson 432 and have no desire to look any further. good all around speaker cable imho. my only complaint would be a little too thick/garden hose like.
To this day I haven`t seen any commercial hifi-cable that`s capable of feeding a speaker without major dynamic loss. That`s why I`m using thick massive copper, and I mean thick.
Just be aware that the copper will need about one hour of heavy massage to open up.
This funny things clear up some of the parameters, just not dynamic loss:
The general theory is the heavier the gauge the better. It's simple Ohm's law in effect in this case. The less resistance from the cable, the more power goes to the speakers.
There is no magic between the $1,000/ft. cable vs. the $3/ft. cable. There may be some trivial effect in an OFC (oxygen free cable), but in my opinion, it's not worth the extra money. A conductor must behave as per Ohms' law, no exceptions.
I also don't believe that some cable companies claim that theirs is superior because they overcame the "skin effect" by using flat cable. Nonsense! Skin effect is so trivial at audio frequencies that it's meaningless. Most of the skin effect takes place in the megahertz and gigahertz frequency ranges.
To show my point, look at the size of the wire from the output transformer (or output transistor) from the inside, going to the back of the amp's speaker connector. Most are not larger than 10 gauge, typically if a transformer, about 16 gauge. Then look at the wire inside the speaker going from the connector to the crossover and then to the voice coil. Most wires going to the voice coil are 18 to 20 gauge!
The length of wire going from your amp to the speaker has a finite resistance which has an effect on the delivery of the power. I never understood how a piece of wire can affect the sound of the music. I tried many and never heard any differences. Remember the fairy tale about "The Emperor's New Clothes"?
