Audiosaurusrex / René,
Thinking that others may benefit from your email questions to me, I decided to answer them here, especially since you mentioned it here yesterday.M3 / M5 Turbo S and Triode Master speakers:
With Spatial's Turbo S and Triode Master speakers, Clayton and I have always run AntiCables Level 3.1 Speaker Wires at every audio show we have done. We are very good at being able to put together a demo room that sounds better than the majority, while being one of the least expensive at the show. A tough act to pull off. With this goal in mind, we don't even consider dropping AntiCables Level 5 or Level 6 Speaker Wires into the system. But...
When running the M3 Triode Master speakers in my home, I am free to use whatever speaker wires I want, so for quite a while I ran Level 6, just because I could. About a month ago, I decided to experiment with speaker wires, because I was getting the feeling there was not good synergy between the Level 6 and the M3TM. I tried a pair of my AntiCables Level 3.1 Speaker Wires, and liked them better. Cool!
I think the Level 6 Speaker Wires being more resolving didn't work well with the Triode Master's high frequencies signature. I am not pointing fingers at the Triode Master speakers, as all high frequency drivers have a signature (a sound of their own that is not part of the music). The great thing discovered is that the Turbo S and M3 Triode Master speakers actually sound better with the less expensive Level 3.1 Speaker Wires. The politeness of very low dislocation density pure copper wire has good synergy with the older M3 models.Sapphire Speakers:
At Capital AudioFest 2019 a few weeks ago, Clayton and I again used Level 3.1 Speaker Wires to achieve our goal of great sound for little cost. For anyone buying the new M3 or M5 Sapphire speakers, AntiCables Level 3.1 Speaker Wires are highly recommended. After all, the Level 3.1 / Sapphire combination (along with LTA, LampizatOr, and Innuos electronics), got recognized as a top sounding room by both Stereophile and AVShowrooms.
Even though the Sapphire speakers do not have bi-wire terminals, they can be bi-wires because of these two facts:
1) The Sapphire tweeter is electrically connected directly to the amplifier output (no internal x-over network)
2) The Sapphire tweeter has 4mm Banana Sockets on the back (as you can see in this photo from "SnowPuppy77")
Because of this, factory leads can be unplugged and an alternate pair of speaker wires can be directly connected. Beautiful!
From what I heard at CAF, the Sapphire tweeter is higher resolving, has less sonic signatures, and is more extended than earlier M3 models. Because of this, I am expecting the Sapphire HF driver will benefit from the higher resolving Level 5 ACElectrum™ Silver/Gold alloy metallurgy.
When I get my pair of M3 Sapphire speakers, I'm going to simply start with a pair of Level 3.1 Speaker Wires so they are the same as at CAF.
After they are well broken-in, and I am very familiar with the sound, I'll unplug the factory wires out of the tweeter and run Level 5 directly to them, from the amplifier, for highest resolution. The back of the tweeters have Banana plugs, so it is super easy to do this. One just has to be sure that the two unused factory banana plugs don't touch anything (insulated with electrical tape or shrink tubing).
To answer you question about what terminations to order to do this bi-wire configuration, I recommend:
- Level 3.1 Speaker Wires with our optional Bananas on both ends (connect to factory speaker terminals)
- Level 5 Speaker Wires with Spades on the Amplifier ends, and optional Bananas on the Speaker Ends (connect to sapphire tweeter)
Both can be seen here: http://anticables.com/speaker-wires/2-channel
Having one set of speaker wire with spades and the other with bananas, makes it easy to connect both to the same amplifier output terminals.
Hope that helps.
Please ask any questions anyone has about cabling the Spatial speakers, and I'll do my best to answer them as best I can.
