I saw that the original post about the twenties is closed.
I' had the honour, in 1980, to be the very first reviewer to test the Matti Otala's Citations ( on Italian magazine Audio Review). The result was...Incredible. My opinion was so enthusiast that my review has been used for months as the back cover of, pratically, all the Japanese Magazine.
I always thought that the XX was (is) one of the best power amplifier ever. And the preamp was not so bad too.
During this 27 years I had ( for test, or for my reference amplification) all the best pre and power amp made during this period ( Krells, Levinson 23, 23.1, 20, 20.5, every kind of Macs, every kind of crazy valve amp you can imaging, even the OnGaKu, Rowland's, Perreaux's, Viola, Lamm...
Recently I found a couple of XXP and XX in very good conditions ( except for some transport damages that I'm fixing up) Well, I turned on the Citation's and the impression was exactely the same of 27 years ago.
The one to be in presence of maybe the best power amplifier ever made, and a very very good (and missunterstuded) preamp.
What a glory with my JBL L300 Summit!
Another time surprised by HK: as it was five years ago, when I bought the Valve Citations ones: I,II and V.
Two year ago I decide to show a vintage equipment in my magazine listening room at the Top Audio Show in Milan. Thorens TD 124, Pritchard Arm, ADC ZLM pick up, Citation I and II electronics, Dahlquist DQ 10 Imp, loudspeaker. That was the crowdiest room of the entire show. The sound was simply fantastic ( what an incredible piece is the Citation I preamp! The II amp is a delight, and an incredible powerfull, solid and dinamic driver) and people asked me: "why I should buy all the new, very expensive things exposed in the hundred rooms of the fair?".
Just because word go ahead, and to mantain in the ideal condition a vintage complete equipment require a lot of patience and application.
Anyway,thanks forever to Harman Kardon to had the courage to present in 1980 such a perfect amplifier, with a price that, at time, was considered outrageous ( now it make me smile, looking at the list price of pieces that doesn't have even 10% of that sound and technical perfection).
Someone told me that Harman still service the XX's. Anybody know if it's thrue? For future (hope not) references.
Best Regards to all of you
