Spectron amplifier - new black faceplate?

Hello Mike,

I would express my personal opinion but from my experience I believe that pair of stock of Musician III monoblocks will sound much better then one Musician III with all upgrades.

Better in three-dimensionality, better in finesse, liquidity. To my surprise I do not hear so much improvement in dynamic range and bass or more correct - I do hear improvement there but not in a degree of the improvement in three-dimensionality and finesse.

John and Simon from Spectron explain it that when you use their monoblocks - all distortions originated in the amplifiers cancel each other completely and you listen to music without (amplifier induced) distortions.

All The Best

The rail (internal) four fuses in both Spectrons are now replaced with HiFi Tuning’s. Results are more than pleased. Any kinds of sibilants gone, highs become cleaner, bas tighter, focus stronger, stage excellent… music simply shine. Everything moved near to reality. So, I would say that replacement of rail fuses is something worth to be tweaked.

Best regards,
Boris

Hello Boris,

Actually you are correct. About 8 months ago, I helped to introduce, in Spectron amps, ceramic silver Audio Acme internal (rail) fuses because four-five HiFi Tuning were way too expensive and people who wanted them could upgrade their amplifiers by themselves.

A few days ago, I have learned that Spectron Production found that Acme Audio fuses fail a lot and they started to use regular (like in Radio Shack) fuses.

While I don;t know if you replaced four ceramic ACME Audio fuses or regular ones - for the owners of recent Musician III Mk2 or Hybrids Mk2 I would definetely recommend that you did - exchange their rail fuses for HiFi Tuning Fuses. The main fuse is HiFiTuning Fuse.

Let me remind that you if you go for this upgrade then you need Fast Blow, 10-12 Amp, 32 mm fuses and Cable Company (salesperson is John Pharo) is giving Spectron discounts.

Thank you again Boris for drawing my attention to this matter.

I just checked my Spectron main fuses in my 2 amps and they were Hi-Fi Tuning, but to my horror one of the fuses had "leaked" the internal damping material into the fuse holder - it was a sorry mess to clean up. At first, I thought maybe a cap had leaked, but it was just the fuse. The fuse was obviously still working and until I replace it I assume the fuse itself is OK, just the ceramic damping oozed out.

I am moving to Furutech and I recommend all Spectron owners to check their amp(s)

Before upgrading were both Spectrons equipped with regular fuses and after upgrading they come with 15A ceramic internal fuses! So, I replaced ceramic fuses for HiFI Tuning’s Fast Blow 10A. I can only hope the between 10A and 15A is not any huge sonic difference.

Regarding HiFi tuning fuses, I newer found any failure or quality issue despite that my system benefit from total of 30 pieces.
