Trenner and Friedl RA box and ํŒŒ๋ผ์˜ค






Music so clear and intense that it is difficult to listen only to the sound. 

The finest birch plywood, selected veneers, sheep wool as insulation, the paper cone impregnated with six layers of Italian balsamic oil varnish ... All proportions consistently in golden ratio, up to the wiring. 

No visible technology, no vanity: 
All subordinated to the music! 

๋น„์Šทํ•œ ์ปจ์…‰์œผ๋กœ ์ œ์ž‘๋œ ํŒŒ๋ผ์˜ค ๋ฐ”์ฟค๊ณผ ๊ฐ™์€ ์ €์ถœ๋ ฅ ์•ฐํ”„๋กœ๋„ ๊ตฌ๋™์ด ์‰ฝ๊ฒŒ ๋†’์€ ๋Šฅ๋ฅ ์„ ์ž๋ž‘ํ•œ๋‹ค.


We developed RA because a small inconspicuous Amplifier with 8 watts fell into in our hands. Conventional speaker systems gave us an idea about potential of that little thing. Inspired by our experience with the RA CINEMA system, we embarked out over an old overgrown road and set down new pathways. 
More than ever, synergies have been seen and heard. We reduced until we reached the maximum. 

The Listeners, the music reproduction system and the music itself formed a unit.

Newport Beach Press Coverage The Lotus Group:

“Dead black background... Dynamics... Ease. That is how I'd describe the sound within The Lotus Group room. Hanns Acoustic T60 table, Esoteric pre and amp, speakers are by The Lotus Group.”  http://www.enjoythemusic.com/the_show_newport_2012/sunday/page2.htm
 Lotus Group room with SMc Audio. Lotus G2 speakers are open-baffle, 3-way with outboard dsp crossover ($75,000).  SMc Audio VRE-1C preamplifier fed by Esoteric digital front-end.  This room had that open-baffle freedom from bass nodes with smooth, integrated presentation, perhaps helped by Class-A amplification by Esoteric http://www.audiocircle.com/index.php?topic=102926.80
“…no show would be complete without a listen to the Lotus Group’s open-baffle Granada G2 ($75k), gloriously driven by a HanssT-60/Ortofon Windfeld front end with SMc preamp and Esoteric power and Pranawire. As always its fast, utterly transparent full-range sonics continue to score points with me.” Neil Gader AVGuide          http://www.avguide.com/blog/the-show-newport-beach?page=1
…” exceptionally transparent, lifelike, involving, all without sacrificing an overall neutrality and tonal naturalness…” Paul Seydor – The Absolute Sound http://www.avguide.com/blog/the-show-newport-paul-seydor-analog-and-vinyl
Best sound—cost no object
No one system did it all, so here are four that stood out (in the order in which I heard them): ( (2) The Lotus Group G2 speaker, a three way open baffle dynamic dipole ($75k, price includes DSP crossover, bass amplification, and professional calibration in the home)—one of the very rare “big sounding” speakers that was not at the same time overwhelming—it could scale up or down yet remain true to the music and was always inviting and involving,,,” Paul Seydor – The Absolute Sound http://www.avguide.com/blog/the-show-newport-paul-seydor-analog-and-vinyl?page=1
“The Lotus Group featured SMc Audio and Esoteric, Prana cabling, and of course their own loudspeakers. Always wonderful sound from Joe and whomever he is working with!” Dave Clark – Positive Feedback http://www.positive-feedback.com/Issue61/newport/newport122.htm

Coverage of Highwater Sound with PranaWire Cables:

The dynamics were enough to launch you out of your seat, and the tone was rich, full and bursting with juicy flavor. Then we switched up to another ORG pressing of Mingus Ah Um and all I have to say is this: Oh. My. God.Parttimeaudiophile.com on the Highwater Sound room with PranaWire Speaker cable and Linebacker In-Line Passive Power Filter http://parttimeaudiophile.com/2012/06/03/newport-2012-high-water-sound-presents-cessaro-thoress-tw-acustic/
