John Atkinson's review of DEQX at RMAF 2016 "Color me impressed" - thanks John.

"Returning to the Marriott, I went into the DEQX room on the 11th floor, where the Australian company's Alan Langford demmed for me the latest version of the Premate preamplifier, the HDP-5 ($6500) which uses DSP to correct both speaker imperfections and room acoustic problems and is now Roon-ready. (You can find Kal Rubinson's review of the original PreMate version here.) Using three RedGum amplifiers with tri-amped VAF three-way i93 Mk.II speakers, all from Australia and the latter costing $16,000/pair, Alan had modified the speakers by installing relays to bypass the original passive crossover with a digital crossover implemented in the preamplifier. (The passive crossover was all first-order, 6dB/octave filters set at 500Hz and 2.9kHz; the digital crossover 96dB/octave filters at the same frequencies.)

Alan let me A/B three options, using first a recording of "Fly Me to the Moon," then Stevie Ray Vaughan's "Little Wing": the original passive speaker; the speaker with the digitally implemented crossover with DSP correction of the individual drive-unit aberrations; and the whole megillah, with digital crossover, DSP driver correction, and DSP room acoustic correction. The uncorrected passive speakers sounded okay. The digital-crossover version lost a slight hooty coloration, and the completely corrected version sounded as though it had an extra half-octave of bass extension and more width and depth to a better-defined soundstage. Color me impressed. "

The DEQX has sparked my interest for the future Lm A22 Horn Mid and tweeter project.With talk of Bi/Amp or Tri Amped like the Vaf demo it could be a game changer blending the Horn setup with my narrow room.Utilizing the HDP-5™ • Preamp processor between both setups may be promising..

Thought I might chime in and say thanks to Redgum and Allan from DEQX with whom we've been working with for quite a while.

It was a fantastic opportunity for three proud Aussie companies to get together and support each other in a collaboration taking our products to the world.

Might mention for the sake of accuracy, we worked with Allan leading up to the show and all the modifications to the I-93's were done at VAF by Simon before heading over to the US. We actually re wired the speakers internally with Analysis Plus cable and used silver contact relays rated at 20Amps - he even doubled up on the relays on the woofers.

 

Stump - we're presently getting a rig set up in the showroom in Adelaide, hope to have auditions starting next week!
