DETAILED, MUSICAL, REFINED.

$4,800.00 per pair of mono-blocks, world-wide shipping included

Using Merrill Audio’s philosophy of Audio Purity, the THOR Monoblocks are engineered to every detail. Starting with the trickle down Hypex Ncore technology in the UcD Modules, utilizing the finest components, Merrill Audio encases the design in a solid billet aircraft grade aluminum chassis design for isolation of components and to minimize microphonic vibrations. Ensuring every micro detail is kept, Merrill Audio THOR Mono Blocks delivers exceptional sound and value, precise staging in a superbly musical amplifier.

The value combination is an Amplifier that is very hard to beat with its heritage from the VERITAS Monoblocks.

Beautifully finished in Black Piano Gloss, each unit is a work of art.

The Thor Monoblocks benefit from the technology and research done by for the VERITAS Monoblocks. Machined from Aircraft grade aluminum block, the case is engineered to minimize microphonics. The chassis is painted and backed Piano Gloss Black for aesthetics in addition to good sound.

The signal paths are designed to be the shortest possible, giving you the cleanest audio signal possible. The chassis and layout were designed, whether single height or double height, to have the shortest signal path, reducing noise and lets the speed, control, and dynamics of the sound come through the power amp unhindered.

The largest wire gauge is used to allow for the best transfer of signal. XLR connectors are Cardas rhodium plate over silver and Cardas Patented Speaker Binding Posts with Rhodium plate Copper posts. Furutech IEC with Gold plate is use for the AC.

Footers are Isoacoustics GAIA III for isolation from your platform.

The Merrill Audio THOR mono blocks were among most engaging and sonically flawless power amplifiers I have had in my system to date. At $4,000, they are the real deal, and come equipped with costly performance enhancements no manufacturer I know of is offering at this price point. The $12,000 VERITAS monos get you more power, and perhaps improved dynamics, but for those with smaller spaces and reasonably efficient speakers, the THORs are just the ticket.

The THORs offer a clean window into the music and are completely free of mechanical or electronic artifacts. They are incredibly low noise, and this contributes to their rock solid imaging and sense of space. The Merrill THORs are a bargain for what they bring to the table. Special mention goes to the excellent ANAP cables provided by Merrill as well. I have no doubt they helped extract the very best performance out of the THORs.

These amplifiers are a must audition.

  • Merrill Audio VERITAS and THOR Monoblocks review

    “What the Thors give us then, folks, is a presentation that is both big and clean. Not clean in the typical audio sense, which suggests that there is also sterility, and hence, lack of musicality. I’m talking about clean in the sense that there is no veiling, no artificially added euphony, no excess of anything. Just pure, beautiful music, with just enough natural sweetness to remain ultimately musical. Not synthetic sweetness that comes from saccharine, but from natural sugar, the good kind, in just the right amount. I really had no idea that modern Class D technology could sound this natural and easy in its delivery.”

  • REVIEW: MERRILL AUDIO THOR MONOBLOCK AMPLIFIERS

    “…the presentation displayed a level of resolution I hadn’t heard before. In addition, there was a polish and refinement to the sound, emerging from a black background, that made me want to increase the volume even more. The music retained its ease, drawing me in and compelling me to listen…”

    “I expected the THOR monoblocks to have excellent bass. I also expected them to have a very quick, responsive transient response, and the THORS did not disappoint me in either department. Thankfully, these traits were accompanied by a transparent, natural sounding midrange and treble.”

  • Merrill Audio Thor – monoblocks

    “…But immediacy and detail did not come at the expensive of musicality. Well recorded music always sounded natural, with nice midrange bloom and presence, never etched or harsh, even when playing loud… The extra power delivered by the Thors really helped make the music come alive… drums had plenty of impact and definition and tone, and cymbals sounded metallic but not harsh…Tonally, the Thors are neutral and balanced with no obvious colorations I could detect.”
