The tonal flexibility of the Stereo 40 became evident yet again when I switched to the Fleetwood DeVille loudspeaker. With its livelier balance, it benefitted from the no-feedback setting, cutting down the perceived treble extension a bit and resulting in a slightly softer presentation, but with billowing image outlines. However, there was more to it than just imaging. It resolved layers of orchestration exceptionally well, and low-level detail floated to the surface naturally without the help of any gratuitous upper-midrange brightness. It was far more revealing than that great and beloved classic UL amplifier, the Dynaco ST-70, which practically sounded fuzzy by comparison. One of the critical factors I look for in any power amp is a low annoyance factor. By annoyance I mean a bright disposition, obvious textural grain, or lack of transient speed and rhythmic conviction. The Stereo 40 excelled when it came to the music’s boogie factor, as well as refined grain-free-textures and fidelity to tonal colors. This was most evident on female voice, which was capable of floating in space with emotional expressiveness. Brahms’ orchestral works define beefy musical textures, and the Stereo 40 seemed to be the perfect partner, facilitating a most enjoyable delivery of the Double Concerto.

The Haut Brion—both versions—is a wonderful, expressive amplifier. But it has nowhere near the sparkle, precision, resolution, or extension of the Bia 200. It also lacks the Bia 200’s tight, well-controlled, tuneful low end. It compensates by seeming more immediate, organic, and natural than the Bia 200. Both exist to serve the music, but they do it in different ways. The Bia 200 is transparent, powerful, resolving, fun. Maybe it’s the top end that seems to go out for miles, or the sonorous bass, or how it steps out of the way of recordings and lets them shine on their own terms.

Different people expect to hear different things from their hi-fi—different versions of transparency, as Herb Reichert would say—even as they seek musical truth. We’re all wired for the particular sounds that make our particular hearts sing. The Bia 200 is wired in a way that, for the right person, can make that happen.

NAD’s C 3050 LE fully delivers on its promise of serious audiophile amplification with a side serving of streaming tech in a comfortably/not-painfully retro package at a very fair value. That statement is complicated, however, by NAD’s bewildering array of fully one dozen other integrated amplifier models, including a few that are variously equipped with network streaming/BluOS, DiracLive, and other hybrid-Class D technologies at power levels from 80 up to 200 watts per channel and at suggested prices from a few hundred dollars all the way up to the Master Series M33 that I raved about in these pages a couple of years back and which remains a jewel today at an eye-watering $5999.

I’ve never auditioned a monoblock quite like the Esoteric Grandioso M1X. Its burnished sound flows effortlessly even through complex passages, and its somewhat laid-back presentation, from top to bottom, helps expose fine detail. The smooth, captivating midrange, which produces no listening fatigue, and impressive bass will speak to many an audiophile. Warm-up time and cost notwithstanding, the Esoteric Grandioso M1X is warmly recommended.

Imagine an open sound with beautifully saturated timbres, clear microdynamics and a vast potential for macrodynamics and you have the Allnic T-1500. The bass sound is not flatulent, but its not unnaturally hard and defined like a solid state amp might produce; there is an airiness and space in the treble range that create such a feeling of well being, that one cannot help but grin as one listens. I don’t believe I’ve stated this before, but in listening to the T-1500 I have felt a profound sense of gratitude. A sense that I have been so privileged to hear the music I love and respect played in the intimacy of my home by the finest musicians both living and passed on, and I feel I am sitting within the ranks of the symphonic players themselves.

If you have mid- to high-efficiency loudspeakers that you love, you may find the LA90 to be an ideal power or integrated amplifier for your system, too. I can easily see a single LA90 as the “summer amp” in high-efficiency horn systems. I would not recommend that owners of 2-ohm Apogee Scintillas or Theil CS3.5s, or if you have a large room with only moderately efficient speakers, run out and buy a pair. Some loudspeakers simply need more power than even two LA90s can give.

But unless you have a friend who has already purchased an LA90, your chances of hearing one or trying one out before you buy are pretty much nil. If you are intrigued by the LA90’s potential, you’re going to have to take a leap of faith (with a 45-day return window from Apos or 30-day from Amazon) and buy before you try, just like I did. So, while I would usually finish a review by recommending you hear a product for yourself, that’s going to be difficult with the LA90. However, if you’re feeling lucky (like the signature dialog from the film The Mask), I encourage you to take a leap of faith and give the LA90 a try. I seriously doubt you will be disappointed by its capabilities or performance.
