A.S.I Tango Diamond Speaker
Air is the carrier of sound waves. If not hermetically sealed off by air locks, all the rooms, nooks, crannies and closets in a house including the refrigerator, oven and all furniture with doors communicate with each through the air.
Traditional heavy damping can absorb excess acoustic energies. But such damping also tends to kill off the finest harmonics, dumbs down the performers’ tone modulations and dries out harmonic textures.
Overdamping further undermines the swing of free timing. If one addresses air disturbances directly (primary causes are the loudspeakers and how they interact with a room’s geometry), the quality of sound propagating through the air improves automatically.
This is a direct cause/effect result and our acoustic resonator technology strategically exploits it.
Our Tango speakers avoid any internal damping or fillers for the same reason. Instead, a series of interconnected breathing bores evens out the air pressure differences between the three discrete internal chambers and, via the spinal holes, between the backs of the drivers loaded into the chambers and the room. This also flattens out the speaker impedance. Three acoustic resonators based on the Pro models but smaller line up in front of the oval bass chamber bore to reduce turbulence. This benefits improved harmonic transmission and makes a silk dome tweeter perform like a hyper expensive diamond unit.
Our HeartSong racks use decompression holes in their shelves and lower legs very similar to the two small upper bores in the Tango’s back and inner chambers and the small holes in the RCA barrels and bayonet bananas. These details and more evolved from the acoustic resonator approach of converting air pressure to tension. Our LiveLine cables adapt the resonator metallurgy of precious metals and alloys to the active signal path. This applies my experience with the acoustic properties of specific metals to achieve minimal group delay, high propagation velocity and undiminished harmonics in signal and power delivery cables.
Karan Acoustics KA-180i MK2 Integrated Amplifier
The Karan integrated amp has a cult following. Milan Karan doesn’t change his products on a regular basis, so Karan doesn’t get the brand coverage a more profligate revamper might and the company is up against some of the bigger names in the industry with marketing powers to match. And yet, the Karan integrated has become the doyen of those ‘in the know’, any mention of the product on even the most vituperative forum is met with praise instead of hostility. There are many folk who traded in well-respected Big Brand amps for the Karan… and never looked back. Only Lavardin receives similarly universal reverence and owning one (a Karan or a Lavardin) bestows upon the listener a kind of classy anti-hero chic, akin to ordering an Armagnac when it’s brandy time. So a new version of the 180W Karan integrated amp is a must-hear, if only to stay one of hi-fi’s underground fashionistas.
Karan has adopted an ‘if it ain’t broke, don’t fix it’ approach to the KA I-180, and much of what was good about the original amp is retained. The amplifier is built along differential lines, but drops comfortably down to single-ended operation. It delivers 180watts into eight ohms and 300watts into four, and has a frequency response from DC to light (well, from DC to 300kHz). The rest of the specs are identical, as is much of the amplifier board layout and even the internal geography of the amp. It also has that unique – as in ‘how does he do it?’ – Class A sound without Class A inefficiency. The secret, apparently, is sliding bias, low current and treating the whole voltage rail like the base of a transistor.
- Completely balanced topology with no overall feedback
- Channel separated power supplies from a custom-moulded 680 VA toroidal power transformer, 80.000 µF filter bank and four stages of stabilization/
- Intermodulation distortion less than 0.03% at rated power into 8 Ohms
Primare CD22 CD Player
The CD22 is the successor to and upgrade for the successful and acclaimed CD21 CD player. Every component, from the CD transport to the audio output stage, has been designed to achieve the highest possible audio performance.
It incorporates a dedicated CD-transport with a considerable five second buffer memory in order to provide the best jitter suppression and protection from mechanical shock. Operation can be customised by choosing the preferred sample frequency: 44.1 kHz, 48 kHz, 96 kHz or 192kHz.
Comprehensive outputs include unbalanced RCA analogue, together with SPDIF and TOSLINK digital outputs. The CD22 will also play and control MP3 or WMA files via USB or disc.
