What is this strange creature with an upper driver that looks like something from a Marvel movie? Is it benign, or is it the blob that obliterated Kansas?

Krell’s immensely energetic Walter Schofield was in the middle of a system description when I entered the room, so I didn't know exactly what I was hearing, but whatever it was, the fact that I’d just submitted my review of the Krell K-300i integrated before boarding a plane for Denver left me very eager to hear it.

In the Gaylord Hotel’s North Tower, where room after room, regardless of its size or layout, seemed conducive to good sound, Raidho Acoustics was making a major impression with the world premiere Raidho TD2.2 2.5-way loudspeakers ($46,000/pair in black).

Paradigm’s Canadian-designed-and-engineered Persona 7F loudspeakers, which have beryllium diaphragms, anchored a system that received additional grounding from the Paradigm Persona SUB ($6500). The sub’s six 8" woofers are powered by a 1700W “Ultra Class D” amplifier that, aided by DSP and other stuff, descends to a formidable 12Hz.

I hadn’t planned to visit the Göbel/CH Precision/Kronos/Bending Wave USA room, having spilled a lot of ink on Göbel and CH products at Munich High End. But, given that I’d heard everything in the room before and was familiar with the excellence of its sound, I wanted to see if it could surmount the sonic difficulties posed by the Gaylord Convention Center's huge rooms.

Saturday September 14th from 6 pm–10 pm, Excel Audio in Newport Beach, California, will be hosting its second annual Customer Appreciation night. In attendance will be representatives from Wilson Audio, D’Agostino, Luxman, Clearaudio, and Impex Records.

Eye-catching as all get-out, Alsyvox Boticelli loudspeakers ($89,000/pair)—having arrived from Spain with their optional external crossover ($25,000) —made a useful connection with Italy’s Omega Audio Concepts DNA CDP disc transport ($12,000), DNA DAC ($9000), and DNA mono amplifiers ($20,000/pair complete with integrated preamps) to produce intriguing sound.

High End by Oz and United Home Audio joined together to present the US premiere of Vitus Audio’s SIA-030 30W class-A/200W class-AB integrated amplifier ($40,000) and AudioSolutions Virtuoso M loudspeakers ($32,000/pair).

The Hellena MK II uses a 604-8E alnico coaxial driver, made by Great Plains Audio, that owes its design to the original Altec 604-E. Its woofer, Great Plains Audio’s handmade Model 515-C low-frequency loudspeaker, incorporates a massive alnico V magnetic assembly. There's also an alnico horn supertweeter.
