Looking for a Giant Killer Digital cable
S/PDIF TOSLINK fiberoptic is actually a very horrible cable. The reason is that the LED or light generating source just cannot light up fast enough to transmit the digital square waves properly. It comes across as a very squirly looking wave (not ... 
Looking for a Giant Killer Digital cable
Oh, if you're building your own cable and looking for a good BNC connector, check out the Furutech Rhodium BNC. 
Looking for a Giant Killer Digital cable
Few things I have learned about digital coax cables:- BNC connectors are best, but need to get closest to a true 75 ohm RCA connector as possible.- For cable composition, solid-core is best with silver-plated or pure silver being the desired for d... 
Stand Alone Super Tweeter for Revel F208?
The B&W D2 have the woven Kevlar midrange drivers.  These are nice, but they do suffer from the typical Kevlar breakup.  This is most likely what you are hearing. 
Stand Alone Super Tweeter for Revel F208?
Agreed on previous comments - a super tweeter will not add sparkle.  Most of these drivers can and will reproduce frequencies up to 20khz and beyond.  You will really not "hear" anything a super tweeter would potentially add, unless you have a ver... 
Bi-amping vs. bridging
I was just going to chime in here.  It really depends on how you are generating the signal for low/high biamp cables.  If you use the "special bi-amp" feature in most processors/receivers, they usually have a circuit that analyzes the actual signa... 
Advice needed on Amp
You could upgrade the amp to something like Parasound A21 (which would definitely be an improvement) at something like $1800 used.  This would definitely increase the resolution/transparency.  I would also look at your interconnects, as solid-core... 
R2R Dacs $3K or under
Don't forget Audio-GD  R2R 7.  $2580.  I've read that Audio-GD has a very nice non-fatiguing sound. 
Rotel rsp 1572 anthem statementd2 or krell s100
Well, if you were looking for longevity and reliability, I suspect the Rotel is the way to go.  It is new technology (still a current product).  It support HDMI and all the current BluRay audio formats.  However, it is op amp based and does not ha... 
Preamp under $2,000 used
Look at a Krell KAV-280p preamp and then re-cap the power supply.  Make sure to increase the 4x3300uf main power supply capacitors to 4x6800uf.  This makes a huge difference and fixes the typical Krell "cold and bright" sonic signature.  Cost of t... 
I need help setting up Two Reference power conditioner 20Is on the same circuit
Just saw m-db's post where M1 idle current is 33 watts, so correct my statement above.  However, recommendation still stands at 2 amps per 20A circuit, but you could probably stretch this to 3-4 amps. 
I need help setting up Two Reference power conditioner 20Is on the same circuit
That's a lot of amplifiers.  Ten 1,000 watt monoblocks.  I would not advise hooking all of them to one 20A circuit.  There is a huge risk of over-draw and possible fire at this point.  I don't know the current draw, and the M1 are Class D amps, bu... 
Fuse upgrade worth it in subwoofers?
I have actually done fuse swapping in an XPR-1 amplifier that I use to power two 12” passive subs.  Fuses will definitely affect/improve/change your bass.  You can tune your bass tones to be more warmer/thicker (I.e. Isoclean fuse), or more deeper... 
Sonus Faber Alternatives That Offer Similar Sound and Performance, your expertise needed!
Coincidentally, I looked at those Snell A-7. It appears that they use the Seas coated paper wooofers, so they would sound closer to the Sonus Faber type of sound. 
Sonus Faber Alternatives That Offer Similar Sound and Performance, your expertise needed!
As a comparison, I initially built these speakers with the Seas coated paper woofers (which would be closer to the Sonus Faber sound).https://m.youtube.com/watch?v=V8s7w04WKik If you listen, you can tell they are more laid back with the “attack” a...
