USHER BE-20 + Spectron Musician III MK2


Hi,
I have Usher BE-20 and looking for a new power amp./ pre-amp., any suggestion?
I did search in the forum and found a recommendation on Spectron Musician III MK2 and Joule-Electra LA-300ME. If I go with both(don't have a chance to audition both at home), what do you think?
My source is EMM Labs DCC2.
Thanks in advance for any comment.

Spectron Musician III MK2 and Joule-Electra LA-300ME, Is it really matched? Spectron is balance design but LA-300ME is single (RCA) design.

Any comment?

Thanks in advance.
Hello Natty,

To answer properly we have to go into rather specific details of these components and I do not believe that this is wide knowledge, so let me try to answer your question(s):

1 Joule-Electra is reality is NOT pure single ended preamp. This line stage uses a phase splitter to process the unbalanced audio inputs as two BALANCED signals thereafter dramatically reducing preamp induced distortions and then sum them together before the output.

2 Spectron stereo is not fully balanced amplifier. It has balanced inputs (w/XLR) and outputs.

3 Spectron monoblocks are fully balanced regardless of your input be it XLR or RCA - makes no difference.

4 I have read that you are particularly concern about the highs in Spectron. I believe its highs are very good as is but we also offer so called V-Cap upgrade where Oil and Teflon caps are installed into power supply for additional filtering - this produce even better (silkier) highs and midrange. There are other things can be done in amplifier to further improve it e.g. installation of four HiFiTuning rail fuses will add to "liquidity"

I hope I answer your "technical" questions.

Simon,
Thanks for your answer. Regards to my concern about high and mid range, I'm worry about "whether it will be too much high/mid or not due to BE-20 is using Beryllium tweeter and Beryllium mid.".
Hello Natty,

I understand your concern. Better power supply filtering just clean music's highs and midrange from all kind of garbage electrical current brings with it even with best power conditioners. It should not add or subtract anything.

Beryllium tweeter and Beryllium mid are also do their job of "honestly" transmitting signal they receive with no or ultra low coloration - this why your concern is absolutely justified as any abnormality will be more readily shown itself with B-20

Good Luck.

Simon
