Must Have Gear: DSPeaker Anti-Mode 2.0


...The Anti-Mode 2.0 Dual Core unit applies an audibly effective correction algorithm to two channel systems .... the results are absolutely phenomenal.

.....there was no question about the Anti-Mode's impact on the sound stage. "Its operation literally made imaging bloom to life with a sharpened intensity and depth"

..... I left a believer and can confirm that the Anti-Mode should be a serious contender for enthusiasts looking for a two-channel Room Correction option.

ADDITIONAL SYSTEM INFO FROM SIMPLIFI AUDIO - At the Recent CAF Show in Washington D.C. we used a SIMPLE IN-EXPENSIVE system comprising a $ 100 Universal Player and a standard Toslink Cable to drive the $ 999 Dual Core. Speakers were the FULLY ACTIVE Mastering Grade Klangwerk Ella speakers from Switzerland $ 14,990 / pr.

California Audio Show 2011

07 August 2011

Gradient Revolution Active - Awarded BEST SOUND at SHOW at the recent Bay Area CAS show by EnjoytheMusic.com
- a report by Clarke Robinson

"My favorite sound that I heard all weekend.... The bass in this room was perfect... impactful, but not boomy, and fast.....and there were no room treatments used.

There is a section in "The Real Blues" where Ray Brown plays a fast run down to the low E, slapping the strings all the way. This tight combination of high frequency and low frequency information is a mess unless the bass is lightning quick, and I didn't hear it played better on any system at the show.

You hear the exclamation, "the speakers disappeared" all the time, but when it really happens, it is breathtaking... and my breath was taken by the Revolutions. They projected a sonic hologram... when I closed my eyes I felt I was no longer in a hotel room at all.

When it needed to, it placed a solo performer right there in the room with us. For larger-scale recordings, sound seemed to come from well beyond the physical walls.

After hours on Sunday I got a brief demo of the Helsinki 1.5s ($6,495 per pair), the Revolution's stylish younger brother, and he was right... with only 2 bass drivers the Helsinki's filled the room just fine.."

SYSTEM SUMMARY BY SIMPLIFI AUDIO ( Total System cost under $ 26,000 )

  • Source was a Resolution Audio Cantata Music Center ($6000), a preamp / DAC / CD / network audio player

  • Power Amplifier was a four channel FOSGATE ($ 500)
    - Speakers were the Gradient Revolution Active System with SW-D towers ($ 11,995 + 6,995)
  • This under $ 26k system ultimately won OVERALL BEST SOUND at SHOW over the mighty fine 10 times the price $ 263,000 MBL system.

StereophileGRADIENT REVOLUTION ACTIVE SYSTEM impresses and surprises
- reviewer Stephen Mejias

Stereophiles Stephen Mejias finished his CAS show coverage at SIMPLIFI Audio's Gradient Revolution Active room stating 'This was one of my favorite listening experiences of the California Audio Show.'

'While many exhibitors at the California Audio Show struggled with the sound of their rooms, employing careful, creative speaker placement and a variety of room acoustics treatments, SimpliFi Audio’s Tim Ryan seemed happy to ignore the room altogether..... I was surprised to see that Ryan had used NO room treatments whatsoever.'

NEWS from 'T.H.E. SHOW' at NEWPORT - June 3-5, 2011

- coverage by Dr. Robert E. Greene

I carried around an excellent recording I know well (Eargle's recording of Dvorak's New World), which I have listened to on quite a few carefully corrected systems.

The Gradient Revolution Active plus [ the SW-D ] towers is an idea that really works.... Excellent truth to tonal character, solid precise bass, correct sense of space, good all around.......

Sounded a lot like an orchestra, to the extent that can be done in a small room.... they were in the very top echelon....

Gradient Revolution Active with SW-D Dipole Bass towers impress TAS reviewer Paul Seydor

Tim Ryan’s SimpliFiAudio room, featuring the Gradient Revolutions Active system, with the Gradient [SW-D] subwoofers presented the most accurate replication of a full orchestra with respect to timbral accuracy and tonal weight, and it was certainly no sluggard in the dynamics department.....

I am delighted my colleague Robert Greene will be reviewing this new Gradient setup - not least because I'll get to hear it in a domestic setting - as it is one of the best I've ever heard.

TAS reviewer ALAN TAFFEL was also drawn in by the Gradient Revolution

Gradient craftily left their room door open, and I found myself incapable of walking past without being drawn in by the wonderful sound. These speakers, at $8000 for the passive version and $12,000 in active form, are clearly worth further evaluation.

coverage by : Michael Lavorgna

San Diego based [Distributor] SIMPLIFI Audio was showing the Gradient Revolution Active loudspeaker ($11,995/pair) with the Gradient Revolution SW-D dipole woofer modules ($6995/pair)....[and were using] a "$500 Fosgate amplifier" with DNM $12/ft speaker wire to show that you don't need to be spendy to get flat response to 20Hz. .

Also in use was a pair of the DSPeaker Anti-Mode 8033G ($595/each one per sub-woofer) a digital room-correction device [which SIMPLIFI market under the name SMARTBASS]..... "the cure for boomy bass."..... From what I heard, it works.

"To find a conventional speaker/amplifier combination that is comparable in sonic quality [to the $ 2390 / pr. A14Ms] I had to move up to the Joseph Audio Pulsars ($7000/pr.) driven by the Bel Canto M1000 II amplifiers ($5000/pr.)…. [a $ 12,000 conventional speaker / amp combo] !!!"
