Synergistic Red Fuse ...

Have over 70 hours on my SRB 800Ma (2) fuses in my ModWright Sony 5400 and it's no doubt that they are transparent and capable of retrieving low level detail but I still feel they need WAY more time to sound their best. While the sound is open and detailed, it's still forward and a little hard in the upper region...

I spent about 40 minutes flipping them to discern the correct orientation; one side of the fuse is fuller with less detail and the other side is much more dynamic, better channel separation and more vibrant sounding.

I've read that they can take up to 200 hours to fully burn-in, so I'll give them another 5 days of continuous use and my lets them rest 24 hours before continuing burn-in.

More to follow... 

According to Dan, the correct fuse direction in PS 9.0 and 9.9 is rear to front.

Wig:
That is a good description you wrote of the sound depending on how the fuse is orientated. I absolutely agree with giving them a lot of break in especially with SACD players. Maybe a couple of on - off cycles  over the next 5 days. That's an unscientific observation of my CD player responding to some on - off cycles.

I should have gotten the Sony, the Marantz SA11-S2  has 5 fuses !

My last shipment of fuses has a note in the box. It points out the BLACK fuses have a small circle of UEF material at the middle of the fuse barrel. Be careful not to scrape that off putting fuses in and out.

Do not forget any sub woofers in your systems. They really respond to the Black fuse.

As I type I am listening to Grammy winning classical celloist Zuill Bailey playing duets with guitarist David Leisner. The album is "Arpeggione". I have been fortunate to hear Mr. Bailey multiple times including in the recording studio. The Black fuses are really bringing out the bite of the bow across the cello strings and the wonderful low and complex harmonics. At the same time the delicate overtones are there with David Leisner's  guitar work.

I do hope all reading this thread will consider trying the Black  fuse. I think they are worth the effort to audition and they can be returned if they do not work in your system.

Black fuse installed in the DAC wasn't my cup of tea.

Beeswax fuse has an organic rightness and is incredibly dynamic/expansive, but just too aggressive with glare in the DAC.

Just received the Telos Quantum X2. So far it's promising - delicately refined and warm with a sweet tone and a bit of bloom.

Macdude, where did you order the Telos Quantum X2 from?

I looked at their distributor list and couldn't find their fuses...
