Reviews & Awards

"The NSEQ and TCL2 are the most pure, clean, clear, transparent, and natural music sounding EQ and Compressor ever!"
Kip McGinnis, Bardstown Audio

“Since adding the NSEQ-2 to our mastering rack, about 90% of our customers have preferred it against all other parametric equalizers in our mastering chain.“
Denny Purcell, Georgetown Masters, Nashville

“The NSEQ-2 joins the ranks of the world’s premiere
Bob Ludwig, Gateway Mastering

“IT’S SIMPLY FANTASTIC! We in studio are astonished about the transparency of the sound comes out! We have a xxxx in one room with xxxx and in the other room we have xxxx xxx, your EQ is second to none!”
Fabrizio De Carolis, Reference Mastering Studios,
Rome, Italy

“Using the Millennia NSEQ-2 has made me completely re-think how I use EQ. Where I used to avoid using EQ at all, the NSEQ-2 has been employed to put just the right touch in a recording. The NSEQ- 2’s transparency and musicality is stunning! I don’t know of an EQ, digital or analog, that could approach its qualities.”
Michael Bishop, Telarc International

“The most transparent equalizer I’ve heard to date.”
Tom Jung, DMP Records

“...the transparency of the signal path is remarkable, and the smooth musicality of the EQ bands as they are adjusted is something special... both [vacuum tube and solid state topologies] are astonishingly clean.“
Richard Foister, Studio Sound Magazine, UK

“...this is an excellent machine capable of very fine results irrespective of the of the technology in the amplification. Although, like most sane people, I would normally find it difficult to enthuse about a simple equalizer, this really is something very special and I have only come across one other similar device which I found as audibly exciting. I would expect [the NSEQ-2] to become a very common entry in the equipment inventory of most mastering houses and top-end studios over here once the word gets out.
Hugh Robjohns, Sound On Sound Magazine, UK

“I believe the NSEQ is, audibly, the most perfect analog equalizer I have ever had the pleasure to use.”
Dr. Fred Bashour, Pro Audio Review

“The bottom line: For mission critical EQ applications where transparency is a paramount necessity, the NSEQ-2 is king. Prepare to be thrilled.”
Michael Cooper, Mix Magazine , Feature Review

"You've heard of the mythical 'straight wire with gain.' Well, the NSEQ-2 is as close to an analog 'straight wire with gain' as I have heard in 27 years of audiophile and professional engineering work."
Bob Katz, Chief Engineer, Digital Domain Mastering, Florida

"You've made a believer of me, and redefined the concept of "neutral" Eq. The clarity and transparency of your EQs is much greater than the AD/DA converted DAT sources that comprise the bulk of our work today. It's truly a breakthrough product, and redefines clean, neutral tonal control in the analog domain."
Dave Davis, QCA Mastering / Ultrainteractive.
