Re: Rocky Mountain Audio Fest - RMAF - Show Report 2015

Well Rounded Sound showed their unique 2-way loudspeaker, the EXP SE with stands for $5,000 a pair. That seemed a little steep, but the pair boasts a unique cabinet construction that took several years to develop.

The cylindrical cabinet design is basic to all their models. The two-way approach delivers very nicely following the point source design approach.

The German Physics Carbon Mk IV at $31,350 per pair is a mature implementation of the unique Walsh driver. The soundstage is one you can walk around in. The ability of the omni driver to elicit detail cohesively is something you need to hear.

Dennis' impressions - I, too, noticed strong central images even when standing well off center. The Walsh driver was well balanced from it's shimmering highs to a hefty bottom end.

There has been a lot of hype built up over the latest ELAC budget speakers, chiefly because of Andrew Jones' hand in the design. I am here to tell you that the reputation is earned. I expected the price of the towers to be around $750-800 pair, which my ears tell me would be a fantastic value, but my guess was way off. The ELAC F5 towers are only $279 each.

From Friend and Fellow "Covered" to Rage Against the Machine "Killing In The Name", these loudspeakers handled all, punching well into the territory of 4 figure speakers, I dare say.

I included a shot of the ELAC S12-EQ subwoofer, but it was not in use, nor was it needed for music.

I walked into the RIVA room and was treated to a little wireless speaker making a surprisingly big sound, the RIVA Turbo X.

The mini speaker has two modes, Normal, which I listened to, and Turbo mode, which adds a combination of EQ and compression to simultaneously boost output up to a claimed 100 dB while keeping the drivers out of the danger zone.

Re: Rocky Mountain Audio Fest - RMAF - Show Report 2015

The Audiomachina Maestro GSE, at $80,000 per pair, is another speaker that pulled a good disappearing act. The TechDAS AirForceTwo turntable, a massive machine, ran into Einstein preamp and amps. Even in the off-center seat, the soundstage came free of the speakers.

Once I thought I heard the tweeter standing out slightly, but if I stopped thinking about tweeters and just relaxed and enjoyed the music, it all came across smooth and sweet.

Re: Rocky Mountain Audio Fest - RMAF - Show Report 2015

Audioengine is a company I have grown to admire for budget audio products with great performance and value. Their new HT6 powered monitor, not yet shipping, will retail at $750 per pair, and features bluetooth, optical, and analog inputs. Amplification is class AB. Their 24-bit DAC and and a hefty power supply are part of the design. A remote is also included, The sound was balanced, full, and clean. A full review is in the works.

The Vapor Audio Nimbus was also at the show. The Nimbus is a three-way design with woofer, and a pair of midrange drivers and RAAL tweeter in MTM configuration. I have heard the Nimbus before, but it has been awhile.

The Nimbus performed as complete a disappearing act as any system at RMAF. They simply were not there. I love when that happens. Their sonic delivery left me little to say, it was that near perfection. Huge, open soundstage and pinpoint-sharp imaging from the MTM configuration were flawless.

It can be argued that a two-way design has a simpler lobing pattern and therefore is a more ideal point source design, allowing some setup flexibility. But I keep loving good MTM designs, with care given to placement, especially height and vertical angle to the listener, as was the case with the Nimbus (they were just a hair low). The imaging was truly pinpoint, the sound was concise and impactful, they did everything right, and I can say that without reservation.

Kickstarter upstart, U-Turn, featured a novel idea for entry level turntable playback. Begin with the Orbit Plus 'table, outfit with options as needed (acrylic platter and cue arm included, here) add RIAA EQ and boost the signal with the U-Turn Pluto phono stage and top it off with A5+ powered speakers from Audioengine!

Avantgarde Duo Mezzo provided effortless (can one find the bottom of a 107 dB efficient loudspeaker?!?) top to bottom 10 octave sound, the lows augmented largely the included 10 band parametric subwoofer equalizer. Such transducers are typically limited dynamically only by the electronics in front of them. Speaking of electronics, check out the beautiful ARGENTUM phono stage from Ron Sutherland.

If there would have been grilles covering the drivers of the Volti Audio Alura, no one would ever know that horns were directing the images on the soundstage of these gorgeous loudspeakers. No horn honk, nothing, zip, zero, zilch. Just invisible performers, playing music in your own personal show.

Certainly, the Tortuga LDR.3 V2 battery powered passive preamplifier using Light Dependent Resistors (LDR) had much to do with this transparency, feeding the signal to the BorderPatrol USB DAC, which features the Philips TDA 1543 chip. No oversampling, no filtering and no buffer, the DAC is said to be as close to outputting exactly what goes in, as is possible. Power was handled by the 18 watt BorderPatrol S10 EXD 300B based Single Ended Triode (SET).

A clean, clear signal path to high efficiency horns that demand very little movement from the drivers, keeping distortions extremely low, made this system a show stand out for me.
