Bel Canto Ref 1000 vs. Spectron Musician III Mk 2


Has anyone compared in their own systems the Bel Canto Ref 1000 Mk II with the Spectron Musician III Mk2? If so, what was your preference and why?

I'm presently using a Cary SLP-05 pre. The speakers are Martin Logan CLX. I have had the Bel Canto in my system previously and thought quite highly of it. No dealers to request a Spectron from to try so interested in forum members view of the latest version.

Need I say more, the head of the Spectron police has spoken. Which part of my response urged Kiwi not to buy Spectron? Is someone Spectron's payroll?
Just to be clear, my Spectrons were great amps and a major upgrade over my various tube amp iterations, but class A (for me) seems to have the upper hand if you are looking for that emotional connection - but as someone said in the thread it is system dependent and always synergy trumps individual components.

One thing though I want to emphasize; several folks came and listened to my system in its room, including an impartial experienced dealer, and for all the overriding agreement was not in favor of the Spectrons, so it is not personal, for the record, or inconsistent with anything I have said previously! As always life is a journey.

If you can listen to equipment at home, this is always the definitive evaluation; the only problem is that a a quick "weekend of home demo, does not do justice and extended listening is required. 30 day home demos are more effective in evaluation. In general I never compare and contrast between one piece and another. That is like trying to say cabernet is better than pinot - they are different and if you have to make a choice, make a personal connection for your own taste - audio or vinous!

I would be happy to have Spectron amps again, its just that I prefer the Plinius sound, nothing more complex than that. Oh, and by the way, before he became a Spectron consultant, Simon's preferred and owned amps were Plinius - go figure.

My Spectron experience: I currently use the latest Spectron monoblocks with all upgrades, driving Marten Coltranes. My preamp is from Joule Electra. The Coltrane is not particularly insensitive, but the impedance curve is somewhat demanding. The amps drive the Coltranes with ease. From top to bottom, they are neutral in the best sense of the word. Well-recorded acoustic jazz is rendered with sweetness and liquidity. Well-recorded rock and pop is delivered with speed and slam. One word of caution: careful impedance matching between Spectron and preamp is called for: I had the opportunity to demo an ARC preamp, and this was not a good match for the Spectrons.
Impedance matching to pre-amp especially if a tube pre-amp is always a consideration for any amp, not just SPectral or Class D.

Stock Icepower modules have 10K input impedance which is not optimal for use with most tube pre-amps.

BC ref1000 uses stock Icepower modules and has 10K input impedance.

BC ref1000m has a separate input stage with 100K input impedance which should match well to most any pre-amp. It seems to do well with my ARC sp16.

Spectron amps may vary regarding input impedance also from model to model I think I recall, so best to know exactly what model you are dealing with and its input impedance specs if to be used with most tube pre-amps.

I take any user accounts of SS amp performance with a grain of salt especially when used with a tube pre-amp because matching impedance and its effect on amp/pre-amp synergy is not something that many take into consideration up front before buying unfortunately.
You gotta be kidding! Comparing Bel Canto to Spectron ?
Come on!! As everyone knows, circuit wizard John Ulrick
founder of Infinity, built the first class D amp back in
'68 and put in a Infinity active subwoofer. Brilliant!!
Then came out with an outboard class D, the Swamp-1 at CES
in'74. He retains two patents on his switching modules and builds everything from scratch in L.A. and doesn't buy the ICE amps from B&O as Bel Canto, Rowland, Wyred 4 sound, Red Dragon and everyone else. Cheapskates!! Spectron is the real deal. King of Class D. Don't waste your time or money
on any other. Ulrick is the Godfather of Class D. Give the man respect and the honor he deserves ! Buy his amps!!
