Price Paid:  $3000.00 from Belgium

Summary:
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.

Strengths:
Strengths: Power enough for smy KEF reference speakers , musical, good staging.

Weaknesses:
Weaknesses: bass resolution, high temperature. Very bad support. only for this, avoid buying unison produt.

Summary:
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.

Strengths:
musical,easy to find tubes, fantastic on voices and jazz, reliable, low power consumption, remote control, passes without problem the WAF (women's acceptance factor !)

Weaknesses:
none

Summary:
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

Strengths:
Power enough for speakers in general, musical, good staging, never feel harsh in high mid at all

Weaknesses:
Poor bass resolution, dynamic lose a bit.......sorry I compared it with VAC models. So troublesome to setup, plug tubes, caring temperature, etc

Summary:
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.

Strengths:
Warn & sweet vocal voice but cannot catch deep bass

Weaknesses:
Too heavy, power consumption
