D-Sonic is far superior to all my older amps
Over a few decades I progressed from more humble audio beginnings as I started to gravitate toward top of the line
Receivers/ Tuners/ Preamps which were still made in Japan. Quite awhile back, while Circuit City was going out of
business, I bought a whole load of amps/ equipment from them, Audiogon, & others (Amps & such). I used equipment
from Krell, McIntosh, Monster, Yamaha, Denon, Primare, Pioneer, Energy, & finally Martin Logan. While using more
traditional amps that weighed up to 110 pounds a piece & ate tons of electrons, I found that my 250 Watt per Channel
Monster amps drove my Energy Veritas AVS system the best.
Even though I had toyed with Magnepan, it was not until I bought Martin Logan Summits, that I really could appreciate
the best sources at that time (SACD, DVD-A). I then hurt my back (had a spine fusion), moved, & downsized a bit. At that time Pioneer was
starting to use the ICE amp in their Receivers, and I then found Dennis & D-Sonic on the net. I then bought a 3-channel
ICE based amp from Dennis & had it ever since. It is an older configuration, the M2-1500-3 THREE CHANNEL AMPLIFIER
3 x 525w/8Ω,watts per channel @ 8 ohms, but boy did they easily drive the Martin Logans (which do have 2 powered sub-woofers each)! I found that this little & light d-sonic box blew away all my heavy & name brand equipment. I also found that a good 2-channel system blew away multichannel.
Now, one of my Martin Logan Summits is defective, so I am using a Summit plus a ML Center for two channel.
I refuse to pay more thousands of $ to Martin Logan for their rather overpriced stuff & am now waiting on
Axiom M100's B-stock to arrive. My plan is to use the ML subwoofers, while doing 2-channel with the Axioms.
Axiom is yet another company that is a pleasure to deal with & they make their products in Canada.
Since the Axioms are made by the same people as Bryston, they should be good, but I think they are 89 db & have
3 woofers each (& double the other drivers). I am rather confident that my old D-Sonic can drive them, but based on many of the comments
on this thread, I am tempted to get their new higher powered Pascal Monoblocks.
Since my first D-sonic was a bargain 3-channel B-stock at a cost of less than one new 1,500 watt Monoblock, it does give me pause. I think
that I will ultimately get them more as a future amp back-up, than as a real need. I think that Dennis is unique
in this field as putting out a high end, powerful, light weight, amp, at great prices.
Finding ample clean power in amp is hard to do. I still remember being horrified that my pricey McIntosh Home Theater 5-channel 100
watt per channel @ 8ohms (200 watts @4) amp, was clipping at home theatre listening levels in a small apt. living room
running Monitor Audio's Silver 3-way speakers. I later sold that piece of "junk" plus other overpriced brand name stuff
to other so-called Audiophiles who pay way too much for a "name".
Incidentally, I found that as you increase the number of separate amps & components in your system, the more chance you
have of either ground loops and/or power slumps. I solved much of my prior ground loop hum, by running ground wires from
the chassis of all the components to a common ground on a Monster power bank. I used to troubleshoot ground loop problems
when I did Intra-op Brain-wave (Evoked Potential ) research in the OR. Ground-loops & other noise often
could swamp the microvolt signals that I needed to pick up from the brain (e.g. B.A.E.R.). Getting the signal from
the noise needed signal averaging, FFT signal filtering, & other tech, to be able to literally save lives via real time
Many of the same physical principles can apply to signals in the audio domain, as well as, some perceptual / Psychological/ Biological
Psychoacoustic ones. As you get up to a certain age, inevitable high frequency hearing loss, further limits your perception,
so high frequency becomes less of a factor (or you need to boast it way up to hear it).
As oppose to the medical field, there is very little evidence based, double blind, placebo controlled studies that support
many of the myths surrounding Audiophile "opinions". Much of the theoretical differences between amps either cannot be
perceived or may not play a big role in enjoyment in real world uses. Indeed, in some situations, like when I have a noisy
commercial fan cooling me during a hot day in the summer, my Samsung TV speakers [a D-amp] set at loud/ high treble/ dialog, are
easier to listen to than my high end AV system. For sure, it is optimized for dialog and the news, but sometimes, I forget
to switch over & do not notice till a movie has low frequency "booms".
While I do use some "common sense" Physics in my set-up (e.g. keeping cable runs short, low gauge, & shielded), I tend to
shy away from stuff that is/or could be utter nonsense (i.e.. optical cables with gold plated connectors). I am always amazed
by audiophiles that see not problem with paying hundreds of dollars for a simple AC plug, while they have no clue as to what
their AC wiring is doing inside the wall (e.g. ground loops).
In short, after all my experiences, I find that Dennis's D-Sonic Amps are fantastic in every way.
I am hoping that between my age related hearing loss, the multiple drivers in the M100, and the clean power
of the D-Sonic's, will still keep me happy...while not breaking my back...again.
