That was fun reading. Being a first generation Italian-American myself (Sicilian actually) I enjoy reading about Italian designed audio gear. Puzzling that they would take such little care in the packaging. I can't wait for your review of the Music Hall mmf7.3. It's on my upgrade list. I currently use a mmf2.2 that has served me well, especially considering it only cost $300 after the price dropped.

Thanks for your nice comments. The UR is a great sounding piece, even if the packaging is negligible.

Doesn't matter how nice the sound if it arrives broken.

Dear Ken,

I read the review with gusto, you hit this review out of the park, except for a couple of caveats, one the fact that the way less expensive Primo has a bigger sound stage was a great point, and underlays how good the Primo is, and the fact that you were comparing a very affordable integrated to much more expensive Shindo gear, demonstrates how special this gear is, okay so you were having a little less extreme deep bass then you would like. I would say to that, it is still a relatively inexpensive amplifier, I wouldn't expect to be be better in all ways to much more expensive equipment.

We have found the Primo is very sensitive to good cables, especially power cords. We have gotten spectacular results with the Wire World cabling, and good component isolation, which helps bring out the deep bass as well as improving all aspects of the Primo's performance.

In our shop we have compared the Primo to almost all of the major competitors, and quite frankly the Primo smokes them all.

The Primo is a hybrid so you get the best of tubes with the best of solid state, the Primo offers a true glimpse into the magic of really expensive gear.

If you want to hear everything in an integrated amplifier, the more expensive Unico 50 which is now the Unico 90 model, gives you the warmth and huge sound stage of the Primo, with even better bass, and far greater resolution.

We used to sell a very expensive line of Japanese components and ones from Denmark, and when ever you compared the Unison product the customers almost invariably picked the Unison.

Under $10k you would be hard pressed to find a better integrated amplifier, which has this number of magical properties as the upper end Unico line from Unison, the stuff is absolutely killer, and Collen and Marc are the best importers with fantastic customer service.
