Grandinote’s Forthcoming Solo Amplifier

Having debuted his extraordinarily spectacular Mach 8XL loudspeaker ($30,800–$33,000/pair, relying upon end) at AXPONA, Grandinote proprietor/designer Massimiliano Magri and North American distributor Reinhard Goerner joined forces in Munich to preview the forthcoming twin mono, totally balanced, class-A Solo amplifier ($20,000 + choices).




Expected to ship round Labor Day, the Solo t outputs 60Wpc into both 8 ohms or 4 ohms.
It features a 9″ multi-function touchscreen show that may change colour, dim, and be switched from what you may see within the photograph above both to a spectrum analyzer or to a VU meter. Upgrades embody a phono stage (approx. $5000) and streamer (approx. $8000) that may go PCM information as much as 768kHz and DSD as much as 256. MQA shouldn’t be within the playing cards for this child.




“It can function an entire entrance finish in a single field,” Goerner (above) mentioned. The extraordinarily exact quantity management has 68 steps, and its reed relay is claimed to be devoid of switching noise and stay “very silent.”

Dan D’Agostino’s Dazzling Unveil of the New Relentless Epic and Epic 800 Monoblocks and Momentum MxV Integrated

In the extraordinarily massive, all-sonic-bets-are-off, glass-enclosed Atrium show mounted by Mansour Mamaghani’s Audio Reference Munich, Dan D’Agostino, and his indispensable sidekick (aka firm President) Bill McKiegan, joined forces with Wilson, dCS, and Perlisten to blow folks’s minds. When the brand new Relentless Epic and Relentless Epic 800 mono amplifiers obtained fired up, it was a case of which dazzled you first, the sound or the sheer enormity and shine of the show.


The Relentless Epic monoblocks ($349,500/pair), accessible now, accommodates a $49,500/pair improve to the unique Relentless Epic launched a yr in the past in Munich. The Relentless Epic 800, which I insist on calling the infant Relentless, outputs 800Wpc into 8 ohms and prices a mere $194,500/pair. Both comprise new circuit sections and parts that improve their energy provide, enter, driver, and output phases. No international adverse suggestions is employed. With a close to 50% enhance in class-A working bias, bias is claimed to stay constant and extreme warmth is eradicated. Driver transistors deal with 33% extra energy per system, and the output impedance has decreased. The Relentless Epic makes use of 112 output transistors, whereas the Relentless Epic 800 makes use of 84.


The Relentless Epic united with the multi-box Relentless preamplifier, Wilson XVX loudspeakers, a full dCS Vivaldi Apex complement, and the largest Stromtank battery energy supply on the planet to fill the room with real looking sound. I arrived on the unsuitable time to get wherever close to the candy spot, however the sound, heard standing approach off-axis, was extraordinarily spectacular.




The new hand-built Momentum MxV built-in amplifier ($65,000 plus $10,000 for the optionally available Digital Streaming Module and $5000 for the optionally available phono module) combines front-end expertise from the stand-alone Momentum MxV amplifier with a “new ultra-quiet 2000VA linear transformer and 60,000µF capacitor financial institution to output 250/500/1000Wpc into 8/4/2 ohm speaker hundreds. Its two chassis interlock by way of 30-pin, 30A, gold-plated connectors that eradicate the umbilical twine presently employed on the Momentum HD preamplifier. The result’s claimed to supply “full” bodily and electrical isolation of the audio part from the ability provide.




The Relentless MxV built-in’s optionally available digital module—a primary for D’Agostino—provides connectivity for legacy sources, supply and host USB performance, and streaming. The module, which accommodates an ESS DAC augmented by D’Agostino’s main filters, is field-upgradable and operates by way of a devoted iOS D’Agostino DSM app that gives built-in Tidal, Qobuz, MQA decoding, and unit management. The module handles as much as PCM 32/192 and DSD1024. The optionally available phono module helps low output MC cartridges with over 60dB acquire and loading choices from 100 ohms to 47k-ohms. Finishes for all fashions are both silver or black. For higher or worse, Alexa integration will arrive in September by way of a software program improve.

The Icing on the Munich Cake: McGrath, Fon, Nagra, Wilson, Impex

It had been far too lengthy since I’d skilled a Peter McGrath demo, not to mention one during which the grasp recording engineer and Wilson Audio Brand Ambassador had a full hour to share his recordings. At final, on Sunday at 2pm at Munich High End 2023, Peter adopted Abby Fon (under) of Impex Records’ packed presentation on Al Di Meola, John McLaughlin, Paco DeLucia: Saturday Night in San Francisco 12 • 6 • 80 to spend an hour within the Nagra room taking part in a beneficiant serving to of among the favourite tracks that he is recorded over time.




Each of Peter’s two shows—the primary was on Saturday—was completely different. At mine, the amount was initially too low to beat the room’s heavy black draping and fill the house. But when it was turned up on the final two alternatives, music crammed the room with probably the most superb, timbrally true sound I heard at Munich High End.




Peter caught to MQA-encoded digital recordsdata performed by his pc. Without its analog entrance finish, the system, which included the identical Nagra recorder that Peter generally makes use of, consisted of Nagra’s new Classic DAC II with discrete class-A output stage ($18,500) fed by the corporate’s Classic PSU energy provide ($16,900), Nagra’s HD preamp ($72,975), HD Amp monoblocks ($99,500/presumably for the pair), Wilson Audio Alexx V audio system (reviewed by Jim Austin in December 2021) with Lõke subwoofers (to be reviewed by moi), Shunyata Research cabling with Altaira Noise Reduction Ground Hubs, and Modulum racks and amp stands. The Alexx V audio system, I ought to add, have been owned by Nagra.




Peter started with one his most up-to-date recordings, of pianist Simon Trpčeski performing a little bit of Prokofiev. Then got here Copland, Mahler, Benjamin Grosvenor’s Bach-Buson Chaconne, Verdi’s “Caro nome” from Rigoletto, a wonderful jazz model of Bach’s Toccata and Fugue in D Minor from Ars Longa of Havana, and extra. With sound as uncolored, stuffed with life, and involving as anything I heard at Munich High End, the hour served as the proper excessive level finale to Munich High End. I am unable to wait to listen to a few of Peter’s music once more when he journeys to Port Townsend in July to put in the Lõkes for overview.

Munich High End #40 Breaks Multiple Records

What a present. During its 4 days within the MOC occasion middle, the primary two reserved for business and press, Munich High End attracted 22,137 guests from roughly 100 totally different nations. With 550 exhibitors and greater than 1000 manufacturers from 54 nations, that they had lots to listen to and see.


With the COVID pandemic in (non permanent?) decline, heaps extra folks wore far fewer masks. In many rooms, the masks wearers amounted to precisely one: moi. Hey, I wish to cowl many extra reveals and listen to much more nice music earlier than I get the chance to find if the Pearly Gates are an ideal level supply.


This yr, the share of business attendees elevated from roughly 38% of all company to virtually half. In complete, 10,748 commerce guests, together with 529 photo-snapping media representatives from 43 nations, finally joined 10,860 members of the general public on the world’s largest audio present.


The present was so giant that the High End Society could not meet the demand for personal assembly rooms. Part of Hall 1—considered one of 4 floor ground exhibit halls crammed with tables interspersed with enclosed listening cubicles— was reserved for the “World of Headphones.” Famed guitarist Al Di Meola was a headline visitor, and famed music producer Rick Rubin was seen wandering the halls, generally previous gaping-mouthed onlookers.


Yours actually did one thing he is performed twice earlier than whereas in Munich: I capped Peter McGrath’s presentation on Day 4 with a stay efficiency of Verdi’s Aida at Bayerisches Staatsoper. (See my evaluate right here.) [ Seated in a chief orchestra seat in Row 13, I heard sound so stay, clear, and interesting as to assist put the whole lot I’d heard at Munich High End in perspective. IMHO, much more necessary than the actual fact I used to be listening to dwelling, unamplified artists from a chief seat was the Bavarian State Opera’s extraordinary acoustic (no less than from the place I sat). As I reminded myself time and again as I contemplated what I heard in a number of reveals, “It’s the room, darling. It’s the room.”




I am unable to faux that this yr’s protection was a stroll within the park. Fellow reviewer Ken Micallef needed to cancel his protection plans when he ended up within the hospital with a damaged ankle, and Stereophile editor-in-chief Jim Austin was knocked low by a abdomen bug halfway by means of the present. Happily, I arrived ready, with lists of premieres organized by location.


Were there much more worthy-of-coverage premieres at Munich High End? Absolutely. But one of many causes I missed them, moreover the sheer lack of time to do the whole lot whereas navigating by means of scores of individuals, is as a result of, in 2023, many high-end corporations appear to assume they’ll skip sending out press releases. Instead, they submit a blurb on their web site or social media web page and anticipate the press to one way or the other discover its solution to their rooms.


But that is my sole gripe. It was a superb present. Some folks complained of an extreme quantity of speaking throughout music. Somehow, I managed to keep away from distracting conversations in all however one room, I positive hope these males’s inventory portfolios are doing nicely, as a result of they should cease obsessing about their choices and focus extra on the music. As for the fool photographer who flashed away throughout a fabulous recording with out the least concern for these round him, the fiery flames of hell await.




I wish to tip my hat to Munich itself. It’s a superb metropolis. From the meals on the English Garden’s Biergarten (above)—the white asparagus was divine—to town’s stay music, surviving and rebuilt structure, and museums, Munich is an excellent place to go to. Readers who’ve the means however have by no means taken the time to go to both Mad King Ludwig’s three fantasy-driven castles or their real-world antithesis, the Dachau Concentration camp, owe themselves a go to. Seeing the sunshine, the darkish, and weird on a single go to is probably life altering. As is listening to the best tools at Munich High End.


My sincerest due to the organizers of Munich High End, to my expensive business associates with whom I laughed and dined, to Stereophile‘s editor-in-chief Jim Austin and technical editor/show-report poster John Atkinson, and to everybody who cares about elevating the bar in music copy. You are a present.
