Before I tackle my diy sub build I need to buy new amps for my main speakers. I am leaning towards replacing my parasound hca-1500's (two) with a class D amp and am leaning towards d-sonic and wyred for sound.

D sonic has the m3-1500 which is rated at 1500w rms at 8ohms and is $2,800 ish for a pair of mono locks.

Wyred for sound has their SX-1000 mono blocks which is around 500w at 8 ohms and is approx $2,600 if I recall for the pair of mono blocks.

They also have a stereo version the st-1000 for a few hundred less and a new st-1000mkii which is slightly less powerful and I think similar money.

Any thoughts or experience with these companies? Presently I bi-amp my old infinity kappa 8.1's with a amp rated at approx 205w x 2 at 8ohms per speaker.

My speakers are in the 4-6 ohm area

I can't decide which direction to go......

The 315 watts per channel of the HCA-1500 (at 4ohms) is not sufficient? I'd suggest running each of your HCA-1500s bridged but Parasound does not recommend that for a speaker with a 4ohm impedance. The amount of power you're looking to get seems overkill. Are the new amps intended for the Infinity speakers or something else?

I considered Wyred to be over priced when compared to Emotiva.

My solution was to go with a 4ohm capable AVR in the form of a Denon AVR4520CI

Note the last part of the review:

"Summing It Up

In conclusion, I am thoroughly impressed with this unit. It has about all the features you could ask for in a receiver/processor and ample power to accommodate most any speaker system. I initially intended on reviewing it and then selling it, but instead I have already sold my Onkyo 5508, XPA-3 amp and XPA-1 monoblocks. I keep thinking to myself that the 4520 seems to be a little on the pricey side, but if you consider what any other processor with the same features would cost you and then add the expense of amplification, the 4520 price actually sounds like a bargain. I think the most surprising part of my experience with the 4520 has been its ability to drive my MartinLogan speakers effortlessly. I had almost given up on ever trying receiver power because I have always read and heard that the Prodigy’s pretty much needed at least 300 watts of good clean power to perform their best. I will have to disagree with the naysayers, as I find it hard to get any better than what it is right now with the 4520 the only power amp source in my system. Excellent job Denon!"

In my opinion, in the end, it's all about the buyer, what the buyers wants out of the deal and how many Benjamins they have to throw at a problem of this kind and in the end, what piece of gear gives them that warm and fuzzy feeling when the individual points to the new piece of gear when their buddies are over to enjoy some entertainment.

The old kappas's many claim hang out in the 3-6 ohm area.

My reason for upgrading is I want better sound quality then what I have now. Going from my adcom gfa-5500 to the parasound was a nice improvement and I want to go a much larger step up in sq (prior to adcom I used my Dennon AVR). I feel my weakest link in my system are my amplifiers and the inability to run Xlr cables.

Power wise yes I think its a overkill however I feel to much power is better then not enough.... Love the headroom :) I also thought that if for same reason I do not like the sound of the amps I could throw it on the sub and have plenty of power to push those drivers.

D-sonic states their best amp for sq is their m3-1500 which doesn't use ice power like many other manufacturers. Wyred's new gen II line of amps is suppose to be similar to their MAmp line which was suppose to be a nice step up in sq.

In regards to the denon AVR4520, been a huge fan of their stuff for 20+ years and still own a AVR-3000. I prefer the sound of seperate amplifiers and use a integra DHC 80.3 as my pre/pro, can't afford to replace that. I am sure AVR's have greatly improved in sq but I still doubt they can come close to the sq of a solid seperate amp.

Someday I would like to upgrade my speakers and being a old infinity fan, the ones I am considering are much harder to drive vs my 8.1's. Kappa 9.1, Renaissance 90 or some from the IRS line which is another reason I want lots of power.

Here's to finding the match which will make your day.

Agreed - I prefer to have too much power rather than not enough if possible.

Rotel's current line of amplifiers are class D. The RB-1572 is rated for 500wpc at 4ohms and priced at around half of either of those monoblock pairs. It sound like you're comfortable paying the price for Wyred or D-Sonic. I have not had the opportunity to hear them, but I'm sure you'll be very pleased with either option.

Never considered emotive products..... Reading up on them

I will check out rotel, forgot about them. Had one of their receivers a long long time ago....

I actually prefer buying these items used so someone else can take the financial hit. But being kinda newish technology they are rarely available used it seems. Local audio shop suggests bryston however that is way out of my price range. A friend has a small audio shop and carries anthem however again..... Out of my budget.

Any chance of getting d sonic or wyred for sound to send you a pair of amps for testing? Also love to know how they compare for sub duty vs plate amps as well as the behringer/crown amps that so many use

I have read up on them and there's no reason I know of to not consider Emotiva's amplifiers. Do you have links to support your comment about "Never consider emotive products?"
lol he said never considereD emotiva. Absolutely worth considering. Especially considering the cost, and the power you can achieve with less investment.

The only Emotiva product I have personally owned was the UMC-1 (which I ended up selling) but 99.99% of the feedback I've heard/read about their amps has been extremely positive. Based on that they are probably the best deal in A/V power amps. If I were to ever replace my HCA-1205A I'd certainly consider them right away.

Viggen, you mentioned interest in buying used - there are two Parasound HCA-3500s on ebay right now. Two mono amps on a single chassis. 500wpc at 4ohms.

That statement was referring to the fact the "I" have never considered their products in the past :) but am interested in them now and am reading reviews on their stuff ! They do seem to be very solid from what I have read.....

In regards to those ebay parasound amps..... that sure would make my wife happy since she is the one with OCD and EVERYTHING has to match!! I just worry they wouldnt be enough power for my not so effecient speakers.... and I doubt I would have the room for 4 of those HCA-3500's :(

Reading comprehension fart on my part. I misread/misunderstood what you posted. Mea culpa.....My bad.

Sorry, sorry, sorry.

You may want to consider other pro-style amps for more power, like the Crown XLS 2500 ( 440W in 8 ohms, 775W in 4 ohms, can be bridged) or the Behringer INUKE NU6000 ( 1500w in 8 ohms, 3000w in 4 ohms). I have heard of many people using Crown amps to power their L/C/R speakers........many also use the Behringer amps, but mostly for sub duty.......

I have looked at behringer specs in the past due to so many people using them for sub duty. It seems very difficult to get actual power specs from their amplifiers. The manual for the inuke6000 does state 2x3000w at 4 ohms and 2x1500w at 8 ohms.... However that is maximum power and not rms power which is the number I am interested in.
