Bottom Line:   
Soundstaging improved over my SS amp. musical but harsh sound with EHx tube. Huge improvement when using telefunken 802s (12au7): detailed mid-range, highs are sweet and smooth.
Drawback : bad, bad support.My dealer never get transfo output replacement after 8 months phone calls and mails.So I got S6 demo replacing my S6 but with no remote. The dealer ordered a remote since july 2004. Until now nothing came from Unison. If you buy an Unison product pray to not needing their support at all.

Bottom Line:   
It's been now 9 month that I have purchased my S6 Unison Reaserch of which I am very satisfied. Great warm sound, very musical (no harshness at all),very good reserve of energy and very detailed as well. This unit deserves good smooth source, interconnect and power cord. If wished, bass can easily be increased by replacing the poor Electro Harmonix by Ei 6CA7/EL34 big bottle or Sveltana's and good 5814.
An outstanding choice for voices and jazz.
I highly recommend it.

Bottom Line:   
Just sold the amplifier and feel a little bit regret when I am reviewing with the buyer. Staging is excellent where I can feel the positioning of the vocal and instruement. Very musical as I never feel on harsh sound. Very punchy when pairing with my ProAc T2000s speaker on stands. However, I do have a complain, the bass, it is not as clear as solidstate amp produces. Resolution is losing a bit. Otherwise, it is a fairy good choice for tube guys to play.....S6 is UR int amp flagship in my heart......coz I dont really like the sound from 845, tube model used by their real flagship S845

Bottom Line:   
It is a delicate amp and the state of art.
My loudspeakers are Harbeth M'40. They are
really good in concerto and soprano's aria. But it's a lttle loose at heavy metal. I think that it does not matter. Because I turn the sound switch over 1200.

Pointing Magnepan 1.6's slightly down....Is this good??

I've been trying to figure out how the custom made stands should be put together that I got with my 1.6's. It seems that the only way that would work with the supplied parts, is to have the back of the 1.6's normal feet raised up an inch. This would give the 1.6's a little downward tilt. I've rea ...

First Thoughts Of My New iMagnepan 1.6's

What a sound! Bright, Open, Warm, Rich....... What other adjectives can I offer?? I love them!!!!!!!!!! I found that bi-wiring my speakers from the amp was a HUGE help. Especially since my amp is 20+ feet from the speakers. Also, the speakers can with 'speaker stands'. These are beautiful wood ... Read More »

Wood's Yard Master Patio Cord on Sale for $6.88

Just bought two 40 ft Wood's Yard Master Patio Cords at Walmart for $6.88 each. These are the basis for the infamous DIY Moonshine White-lightning speaker cables and interconnects which were all the rage a few months back. I doubt you can buy 20 gauge zip cord this cheap. :thumbsup:Read More »

Lucinda William's backup band, Buick 6 (hear me out!)

A friend of mine (yes, I have one) has a convoluted story that I'm not about to type up about how he got a copy of Buick 6's disc. Anyhoo, he made me a copy, and I'm pretty much diggin' it. No vocals, axcept (typo, but it looks aight) a stint by Lucinda herself on a track. They do a Zep cover, which ... Read More »
