The last decade summers at my place have been hotter than ever before. At 6300 feet, what used to be two weeks of high temps has turned into 10 weeks of even higher temps. I know this is just a Chinese hoax, but damn, the heat my tube monoblocks generate is just too much for... Read More »

I was once upon a time in a galaxy far, far way, an unabashed, dyed-in-the-wool tube lover. The mere mention of solid-state electronics sent my upper lip into involuntary quivering. Still, it was important to separate my job as an audio reviewer from my personal preferences. Over the years, products from Levinson, Rowland, Cello, PASS,... Read More »

Background In this time of Covid 19 it was apt that I was given the opportunity to review a product from a small company headed by a dog named Lutz.

Like the biblical hero depicted in Florence, Italy's famous David statue by Michelangelo, the diminutive PA-10 is angular and elegant, but capable of bringing down a giant or two by slinging notes with speed, precision, and wallop. Compact at 8 ½" W x 3 ⅜" H x 11 ½" D and 8.82 lbs., it's the... Read More »

Perhaps because quarantines and lock-downs have freed up a resource many adults lack. That resource... Read More »

      Music lovers come in all stripes and colors. As much as I love the multi box room dominating rack of separates which make up my reference audio system, that kind of space and financial commitment isn't realistic for, or desired by everyone. Often a more modest space saving approach is called for.... Read More »

OK. Given a world-wide pandemic, why are we reading (and writing) audio reviews? First, as Congreve pointed out, "musick hath charms to sooth a savage breast." Second, it's what we do, especially with time on our hands. Up until a few years ago, I was active buying / selling vintage and audiophile LPs on eBay.... Read More »

At the enthusiast audio shows I have visited in the USA over the years, I've always thought that year-to-year, the Audio Note (UK) rooms had some of most consistently excellent musicality & sonics of all the show rooms I visited.

The last 2 years of computer audio (2017 – 2019) for listeners and musicians have been unlike anything I have seen or heard since the earliest exciting and revolutionary days of the introduction of DSD as SACDs into the market which I participated with as an album (SACD The Window released in 2003). After the... Read More »

This review took a little longer than I thought. I originally found out about this amp from my colleague Robert Levi, and could not resist sending EveAnna Manley an email to see if I could procure a review model. She was more than willing to send it out with the 250 monoblocks that I also... Read More »
