Krell Modulari Duo Reference

John Atkinson Jan 12, 2011 First Published: Jan 12, 2011 0 comments

It was released in 2009, but Krell's Modulari Duo Reference loudspeaker ($65,100/pair) was new to me when I visited THE Show and ventured up to the 28th floor of the Flamingo. The two-box speaker features all-aluminum enclosures, and features twin port-loaded woofers and a ring-radiator tweeter. The Modularis were hooked up with Zen Satori cable to Krell's new Evolution 2250e amplifiers, which offer 250Wpc into 8 ohms and 500Wpc into 4 ohms ($20,000/pair). Also new to the Connecticut company's line at CES was the Phantom preamplifier ($17,500, or $20,000 with optional crossover module, completely adjustable for high-pass and low-pass slopes and frequencies) and the 525 CD player ($12,000 in basic form).

Acapella Revises the High Violoncello II

John Atkinson Jan 12, 2011 First Published: Jan 12, 2011 0 comments

A highlight of my reviewing year in 2010 was living with and writing about the Acapella High Violoncello II speaker from Germany ($80,000/pair). With its horn-loaded, ionic tweeter and horn-loaded midrange unit, this speaker offered both high sensitivity and some of the most satisfyingly musical sound I have experienced in my room.

Current production has been modified a little compared with the much-traveled samples I auditioned for my review. (They were the same pair I had auditioned at the 2010 CES, Axpona and RMAF Shows.) The drive-unit complement, cabinet, and crossover are all the same, but there is now a greater range of level adjustment for the ionic tweeter and isobaric-loaded woofers. But the sound of the latest version at CES. driven by Einstein electronics, sounded just as I remembered: dynamic, transparent, neutrally balanced, and not a trace of horn colorations.

More German Horns: the Avantgarde Duo Grosso

John Atkinson Jan 12, 2011 First Published: Jan 12, 2011 0 comments

Avantgarde's Armin Kraus stands next to the new version of the three-way Duo speaker, the Grosso ($36,000/pair). Finished in "Lamborghini Orange," the Grosso substitutes two 12" woofers for the Duo's 10-inchers, and drives them with twice the amplifier power. The midrange and treble horn units are the same, but the speaker is now supported by a sturdier space-frame with spikes that are adjustable from above. And again, this is a horn speaker that offers the advantages of hornshigh dynamic range, sensitivity, and "jump factor"without the disadvantages, such as midrange coloration.

Hegel Music Systems was on hand to show off their ever-expanding range of DACs. The smallest sitting at the top right is the $350 HD2 USB "music streamer" that can handle 24bit/96kHz USB data and output it either as analog audio or digital data over SPDIF.

Under the HD2 is the $1,200 HD10 which offers USB, coax and optical digital inputs as well as both balanced and unbalanced outputs. To the left of the HD10 is the newest DAC from Hegel, the HD20, which in addition to the inputs and 24/192 conversion found on the HD10, offers remote control and display for $2,000.

Jon Iverson Jan 11, 2011 First Published: Jan 11, 2011 0 comments

Mach2 Music offers two services: they will sell you an upgraded Apple Mac Mini computer optimized for digital audio music serving, or take your already purchased 2010 or later Mac Mini and perform their upgrades on it.

They had the first option on hand, which includes a 40GB solid state OCZ Vertex drive to replace the factory drive, Amarra 2.1.1 installed and set up, 8GB RAM installed, cables from Most Beautiful Sound (they cut the power lead in the Firewire 800 cable) and a power cable from PI Audio Group.

Also included, but missing from the photo above due to shipping issues, is a PI Audio Mac Sandwich clamp system. Dayton Audio Brass Speaker Spikes (shown in black) complete the package which retails for $2,995 through the end of this month. All you need to add are external hard drives, a monitor (or iPad/iPod control device) and music.

T+A K8 7.1 Blu-ray HD Receiver

Jon Iverson Jan 11, 2011 First Published: Jan 11, 2011 0 comments

Though not strictly a digital audio product, I'm not sure that anyone else will cover this, so wanted to include it here. In addition to the Blu-ray player and amplification features, the $9,500 T+A K8 sports a full complement of digital inputs including USB, as well as an audio streaming client for most formats.

Cardas gets inside your head

Tyll Hertsens, Jason Victor Serinus Jan 11, 2011 First Published: Jan 11, 2011 0 comments

Audiophile sensibilities have long found a comfortable home inside George Cardas’ head. Also in George’s head for the past two years has been the design of a single-driver, dynamic in-ear monitor that would fulfill his desire for a non-fatiguing portable listening experience. The as yet unnamed little gems are just entering production, and are expected to retail in the $300$500 range. A quick listen confirms that George has indeed managed to do something quite special: glorious midrange. I gladly accepted a sample pair for review; I reckon I’ll be spending a good chunk of time with George’s thoughts and sound in my head very soon.

Cardas’ Expanded Clear Line

Jason Victor Serinus Jan 11, 2011 First Published: Jan 11, 2011 0 comments

George Cardas stands darped in the new Cardas cables whie the company's Operations Manager Josh Meredith was happy to show off Cardas’ Clear Light Speaker cable ($1048/2m pair). Now the lower end of the Clear speaker cable line, it will soon move up a notch to middle position as another model of speaker cable comes out.
A simplified version of Clear speaker cable ($3726/2m pair), its ability to be produced more rapidly results in its considerably lower price.

Also on hand was the Clear Light Rev 1 interconnect ($856/1.5m pair). Now with a larger diameter, improved shield, and nicer RCA connector, it is still substantially lower in price that the Clear interconnect ($2360/1.5m pair). Next on the horizon is a Clear power cable.

Gold Digging at CES

Tyll Hertsens Jan 11, 2011 First Published: Jan 11, 2011 0 comments

Listening to UNLV’s radio station KUNV playing Jazz, I notice the glowing digits on the Droid’s GPS indicating two minutes to turn 1.2 miles away. Riiiight. Notice the speedo pegged hard at zero. This Montana boy has spent the last 20 years regularly attending CES in Vegas. . .ugh. Too many people for me; too much glitz; too many lights. Fortunately, however, patient and persistent digging through the mountains of garish purple plastic gadgets will almost always reveal a modest handful of personal audio riches. That’s why I’m at the 2011 CES: digging for gold.

XLO’s Hefty Purple Rush

Jason Victor Serinus Jan 11, 2011 First Published: Jan 11, 2011 0 comments

Allen Sung, owner of XLO (left), introduced the Purple Rush power cord ($7000/6ft). The first product in the company’s new Purple Reigns series, this substantial baby is heavy enough to easily yank a poorly positioned component off the shelf. IMHO, the cable’s oversized proprietary connectors are as impressive as its girth.

XLO’s designer, Jay Victor (right), explained that he wanted to design a power cable that he could use on high-current power amps in his own system. “I started dabbling in cable design when I was in charge of product development at Monster Cable with Demian Martin,” he said. “We were marveling at how much of a difference different power cables made to a system’s sound. I kept refining my ideas of power cable design, until I came up with idea of mixing different conductor shapes to best convey the whole range of bass sound.”

Victor believes that a large solid conductor is great for low bass, a flat conductor is best for mid bass, and a polymer coated Litz works best for highs and transients. He has combined all three in the Purple Rush power cord. The cord also employs an exotic field-balanced winding technique to lower the noise floor and cancel magnetic effects. All in all, five patents are associated with the Purple Rush power cord, which took eight years to develop and refine.
