Has anyone listened to the new Audio Research DS450M mono blocks or the DS 450 stereo Class D amp's and compared them to the Spectron Musician III MK.2?..

One important technical item..Dennis Deacon with D-Sonic, in our conversation this past Sunday, explained the technical reason why he dumped the B&O ICE amps, is that their is a flaw with B&O ICE and other Class-D amps in the upper mid-range and high frequencies, that they have feed back problems in those upper bands which can compromise smoothness and greater weight in those areas, which is why
some Class-D amps can sound dry, cool, and slightly hard in the upper frequencies. Dennis claims that the new SOA Class-D core amps he's using with his own mod's added, have zero feedback through the entire frequency spectrum
which is why he states, as well as 6Moons, that his amps come closer to tube amps then other Class-D amps on the market resulting in a more refined and smoother high frequency and mid-range frequency performance. I assume that Hypex has addressed this problem with
Bruno's new SMPS 1200 amp, which has positive results. If the new SOA core amp from D-Sonic sounds as good and performs as well as Dennis and 6Moons claims, then its a no brainer to go for
the SOA core amp over Hypex since the cost is 80% less.
I heard the new NAD digital amp and was surprised just how good it sounded...I'm stickin with Class A/High Current designs however. Based on what I hear today, the 90's were "The Golden Years of High Fidelity"...gear does not sound more musical today than it did back then and it often sounds worse:)
Dave b_your right about that. My first amp back in the 70's
was the Sansui AU7900 integrated at 75 watts per channel. One of the finest sounding amps I ever owned. Had it hooked
up to a large pair of Advents and a Dual 701 turntable with
a Shure V15 cartridge. Warm, rich, lush sound with a full mid-range. Ran very hot. You could fry an egg on the back.
The rise of the digital age changed the sonic character forever of high end separates. I would say the late 70's was the golden years of high fidelity. With half speed
cut master vinyl records from Mobile Fidelity and Telarc, and advanced improvements in cartridges and turntables and cables. It was the peak of true analog.
" I would say the late 70's was the golden years of high fidelity. "

I would say yes in terms of market size and # of users, but amps and speakers have come a long way since then. Digital sources as well since their inception in the mid 80's.
Mapman..here's some useless trivia..The first retail CD player came out in early fall of 1982, the Sony CDP-101, followed by the Philips Magnavox players that came out that
November.. CD's started showing up in the stores in fall selling for $ 25.00 a pop. Phew!! However, the very first disc players ever made was in 1980. Pioneer that year bought out a company that invented and made the first laser
disc movie player. Pioneer slapped their badge on the player and were sold under their name. Denon also in 1980, made the worlds first CD player. It was a test player that was for studio use only.
