Resolution Audio has yet to name or price its new 100W monoblock amplifiers, due in May, but they may come in around $9000/pair. Their push-pull design is licensed from English engineer Denis Morecroft. Build is distinguished by custom T-network caps and, in the company's words, "crazy careful attention to detail."

There's a big change in the Bel Canto line, folks. It even comes with a new logo and website, belcantoblack.com. As for the sound, listening to an Elvis Presley outtake of "Peace in the Valley" on a 45rpm pressing from, I believe, Direct Grace, I loved the wonderfully clear and uncolored sound, as well as the natural "you are there" detail. To be honest, I drank it up.

Gideon Schwartz of AudioArts NYC assembled an extremely fast system that delivered maximum color without any of the harsh, irritating edge that I encountered on many systems, both tube and solid-state, at CES. On Salvatore Accardo's well-worn Diabolicus in Musica LP of Paganini's solo violin music, as well as on a CD by the Musicians of the Nile, I was deeply impressed by the upward extension of the tone and the system's willingness to bathe music with the light it deserves. If the system wanted for the last iota of bass impact and clear delineation of low-lying lines, it nonetheless handled bass with a finesse that few hotel room set-ups offered, especially in the case of large loudspeakers sandwiched into small spaces.

Rogers High Fidelity's New York-manufactured, aerospace engineering-based system, which included the just-launched PA-1A six-tube phono preamplifier ($7100) (pictured on the right) and EHF-200MK2 KT150-based, 112Wpc integrated amplifier ($15,000), delivered extremely quiet, beautifully warm and lovely sound with Shunyata power conditioning, Kimber Kable, and Davone Grande loudspeakers. The two Rogers pieces also looked fabulous.

Although the business buzz in the Esoteric room made deep sonic evaluation impossible, I was impressed with the very nice midrange warmth and sweetness of the Esoteric system. I didn't hear any overtones from the new Grandioso M-1 mono power amplifier ($23,000/each), but I expect they were drowned out. A new companion preamp may be out by summertime. Also due from the company known for its excellent transport mechanisms is a new top-of-the-line transport, to replace the P-01, and a new mono DAC, to replace the D-01.

Darren Censullo's Avatar Acoustics did itself proud with a system that, on one of John Atkinson's recordings of male vocal ensemble Cantus, delivered totally natural and clear sound with beautiful layering and air, and natural timbres to boot. And as much as Shelby Lynne's "Little Lovin'" is getting less and less lovin' from me each time I discover multiple rooms playing it at shows—aren't there any other good tracks on her very well-recorded album?—Lynne's bass accompaniment was very profound, and the heart-warming beauty of the sound most impressive.

Is it any surprise Audio Consulting and Scaena, otherwise known as Switzerland meets South Florida, sounded excellent? From Audio Consulting, who were making their first show appearance since 2008, and is now sold direct from Nashville, we experienced numerous products. The first, the Audio Consulting MIPA (Mains Independent Power Amplifier) Silver Rock Toroidal amplifier, is available in stereo 30W ($45,000), mono 120W, and 30W/120W switchable ($52,000) configurations. A battery-driven, solid-state class-A switching amplifier, it has customizable inputs and outputs and is housed in a wood chassis.
