Greetings! I see an "Iggy" installed in your current system.

Hopefully, a review is forthcoming???

I appreciate your writing style, with comprehensive/comparative reviews. (smile)

All the best,

Prima Luna are built by CAYIN/SPARK in China. You should give them a try, they are the real deal and you will find where all that Prima Luna bla, bla comes from. CAYIN is one of the top and most respected chinese audio manufactures. Stereophile published rave reviews of several CAYIN products some years ago. They are tube oriented but their DAPs are also outstanding and worth checking. You can get CAYIN in North America from Audionation in Canada or VAS Audio.

An amplifier with 8 ohm output impedance that will sound different with every different pair of speakers. Great!

I went a different direction, but this is what put the brakes on my interest in their Dialogue Integrated for now. I feel like I need to spend some time with a demo unit mated to my speakers before committing.

Herb, your comparison to the LM518ia is certainly high praise. I have O93s and have been leaning towards the 518 ever since I heard it at my local shop with a pair of the O96s. That stated, I'm a sucker for the midrange from a nice quad of EL34 tubes. To get to the musicality and punch of the integrated LM, which can be spookily good, was your preferred pairing the PrimaLuna with the Rogue Audio RP-1 preamp, which you reviewed earlier this year?

I'd have to think of it as an Audiophile "Gold Standard". The Linn Kan and the ProAc Tablette too.

If a person owns these he's discerning.

Jim Theil's CS3's have the same drivers plus a lower octave woofer.

Your new Lady Reviewer owning LS3/5a is what makes her credible, in my eyes.

We used to have a pair of these playing (non-stop) in our big High-End demo room ( at my Esoteric Audio ), people would walk in and listen thinking they were hearing the Big Speakers in the Center Front. We were using Electrocompaniet Amps.

An all time great Transducer System, way under rated in today's Audiophile World.

Other Greats would include Magnapan MG2, original Quads ( 1957 ), Linn Kan, ProAc Tablette. All of these are "Desert Island" choices.

Now-a-days, a pair of Genelec 8020s with some 6dj8s or 6SN7s ( in the Pre ) are even nicer.
