Ohm Walsh Micro Talls: who's actually heard 'em?

YEs, I thought the same thing regarding D-Sonic and JS/OHM.

One downside with OHM that results is that many CLS drivers look the same on the outside but are different by design internally. That makes it very hard to know exactly what you are getting second hand. Even direct from OHM, you do not know anything for sure really about whats inside, only how it sounds.

One difference is that what makes the OHM sound is JS/OHMs design, whereas in the case of D-Sonic, what makes it is determined by what amp module is used, and D-Sonic does not design or make that hence they have limited control of that over the long term. AMp A today, amp B tomorrow? How are they different? How is the sound affected, etc? Very hard to say, whereas with OHM I think JS designs his products to have a particular sound and he has a lot of control over how to do that, especially given the nature of Walsh drivers and how those are quite tunable to produce a certain result.

As a manufacturer it blows me away that anyone would expect a manufacturer to just openly give away the specifics about anything he makes. In todays world with widespread copying of every single minutia, I congratulate Dennis for standing strong, and not give anyone proprietary info no matter how much you think he owes it to you. I had one of my parts stolen from me, copied all the way down to my own f*uck-up (misaligned holes) in a diverter and the offender (chinese) didn't give a crap if I was upset or if I would call my lawyer.

Mapman: I am not sure I agree with you on Class D amps. While many Class D manufacturers take OEM modules, almost all of them have their own approach to power supplies, input stages, etc. AFAIK, the amp module itself can be made to sound drasticly different depending on the builder's choices for these and other parts of the finished product. Heck, your Bel Cantos use an OEM Class D module, don't they? Yet they are known to sound much better than other brands using the same modules. I could be way off on this, but even the D-Sonic amps include a circuit board and other parts of the signal/power chain that are of Dennis' own selection (if not design). Just my $0.02.

" I could be way off on this, but even the D-Sonic amps include a circuit board and other parts of the signal/power chain that are of Dennis' own selection (if not design)."

Maybe, but I am under the impression that this is not the case from what I have read and seen to date. I do not know Dennis's background, but I get the impression from what I have read that this is not his area of expertise.

But you are right that many or perhaps most even (not sure) Class D amp vendors in recent years add circuitry to improve or tweak performance.

It's quite possible from what I read that with teh newer Class D amp module technologies available currently, there is little need to do much more. That may well be the case with D-Sonic now, though it was not the case when they were using Icepower as their main engine.

My point is D-Sonic has been around for a while now and folks have already heard their previous iterations. The new amps are supposed to be improved. How so? New amp modules (plus whatever else). OK. Many of us have already heard class-d amps and have an idea of what they sound like in general and yes, every manufacturer has their own build/sound, but I would like a more compelling reason to try the amp(s) out other than "it/they sound great". If I want to take a chance I still have to pay for shipping and a restock fee.

"An in-home trial period of 21 days is available. This can be extended by email at the discretion of D-Sonic. If the unit is returned in factory condition and packaging, customer pays shipping both ways plus a 10% restock charge. Unit must be insured to full value."

So .. I don't expect any manufacturer to give away the farm so-to-speak but most will provide SOME info including what amp modules they are using (Bel Canto & W4S for example). No I'm not obligated to purchase, nor am I compelled.
