Spectron Mk II, is it really that good.

Perhaps it is system or speaker dependent or the sound you are looking for but I like my MK2 with V-Cap upgrade (makes it more liquid sounding). The sound is very musical sort of between tubes and SS but with tremedous headroom and tigh solid bass.

I have B&W 803D speakrs that can dip to 2-3 ohms and the Spectron is stable down to 0.1 ohms which really helps....especially if one has electrostatic speakers.

I tried a lot of amps before settling on the Spectron (I like the MK with V-Cap upgrade more) as it works well with my speakers and system. I use a tube preamp and the combination works well for me.

What I didn't use to like were the round black speaker posts that were not suitable for bi-wiring. However they now use a Cardas regular speaker post and it is a welcome change.

I originally purchased a single Musician III SE. I later added a second amp for mono-block operation. As good as a single amp can be, these amps in mono-blocks are in a whole new level. It is often the case that bridging amps does not return double the improvements, or the investment. With the Spectron mono-blocks the performance improvement are quite dramatic.

I recently upgraded the mono-blocks to MK2 status, along with Bybee purifiers upgrades. In my mind, this was a minor upgrade, but I was blown away by how much quieter these amps were after the upgrade. There is more speed, control and finesse. I was told that about 70% of the improvement I'm hearing is due to the Bybee purifiers.

I don't know what the MK2 without the Bybee purifiers sound like, but with them installed I very, very highly recommend these mono-blocks.

Best,

Mdrummer01, My mistake, I was refering to the Musician II. I know they have made a lot of progress with updated versions from what I have heard. My experience with the Musician II and model 10 pre were cumbersome to say the least. After switching to BAT gear, I would never go back to class "D" IMHO, The sound was somewhat colorized .....

I have the MKII with both V-Cap and Bybee upgrades (I highly recommend both) and really love this amp. I found that the break-in time is lengthy but well worth the wait on the other end.

I owned the Spectron Musician III Signature Edition which replaced a Spectral DMA-150 Series II. Whilst I was initially happy, I found that with long term use for several hours a day I came to recognize a distortion which I can only describe as bleached or whiteish high frequencies. Once I had become cognizant of that, I found it extremely annoying, almost to the point of being unlistenable. To mitigate the problem I replaced the Spectron with the far more expensive MBL 9008A monoblocks which are in a totally different league. I was so pleased I posted a message to a forum stating the facts. To my chagrin, I got an extremely rude email from Spectron effectively telling me that I was stupid and I should have forked over $$$ for their monoblocks and associated upgrades. Needless to say I was not amused. I'm glad I got off the Spectron upgrade merry go round at the earliest opportunity. I won't be going back.
