Time to buy a class D amp?

Hello turnbowm,

     While it is true that class D amps in general emit radio frequency (RF) energy that can interfere with AM/FM frequency reception, class D amp designers are very well aware of this issue and typically make containing, controlling and attenuating these RF emissions a top priority in their designs.  
     If all class D amps were to be tested and ranked by RF emissions, however, I suspect the results would vary significantly between amps and that they'd also likely be directly related to the skill level of each amp's designer and the new retail price of each amp. 
     OTOH, I've purchased and used many stereo and monoblock class D amps in my system ranging in price between $630 and $2,200 and have never had AM/FM reception problems in my rooms with any of them.

Best class D i can think of is without a doubt Bel Canto Black ACI 600.Most likely the best single chassis class D integrated amp out there, probably better than more expensive separates.

noble100,

Thanks for your detailed, informative reply. Much appreciated.

Jeff Rowland is an excellent class D ICE POWER amp. Nice option. Very nice.
Try to listen, just it. 
Just it. Just listen.

Hello niodari,

     In retrospect, I’ve been so impressed with class D amps in general that I’ve consistently upgraded to better performing examples over the past 7 years or so. I began my class D journey with what I consider the budget king of D amps, the Class D Audio SDS-440-CS stereo amp, that was a good quality example at the exceptionally low bargain price of $630 at that time.
     Mainly out of curiosity a year later, I bought an even more competent class D stereo amp, the Emerald Physics EP-101.2-SE, on sale at the time for about $1,000 and a noticeably superior performer.
About another year later after reading numerous very good reviews, I bought my 1st pair of mono-block class D amps, the D-Sonic M3-600-M for $2,100/pair that were and are the best performing amps I’ve ever driven my main Magnepan 2.7QR speakers with by a large margin. I’m still utilizing these as my main speaker amps about 5 years later in my combo 2-ch music and HT system. My 2 stereo class D amps I purchased have been  used in my system as surround sound channel amps with very good results and are still going strong.
     So, I’ve been climbing the class D upgrade ladder for the past 7 years and enjoying the entire slow ascent continually along the journey. I’ve progressed from good performance rung to the better rung and I’m currently on the very good class D performance rung of the ladder. Now, I have a keen urge and curiosity about the prospects for my overall system performance quality if I climb another rung higher and purchase one of the best class D amplification examples currently available.
     I currently believe the current top rung of the class D ladder probably equates to the newly released Merrill Audio Element 118 monoblock amps or the Technics model which both utilize the GaN extremely fast switching transistors. Interestingly, I was talking to Merrill of Merrill audio recently and he stated he’s discovered the older GaN transistors sound better than the newest ones.
     However, being now retired and on a reduced fixed income, buying a pair for of either for about $36K/pair for them would likely entail me being required to dine on cans of cat food for my remaining years. As attractive as that sounds, I’ve decided to instead settle for the penultimate rung on the class D upgrade ladder by eating tastier meals and purchasing one of the following 2 preamp and amp upgrades for my system soon:

Option#1. For a total of about $10K, buying a pre-owned Levinson 326S preamp and a pair of Merrill Veritas mono-blocks. Merrill also told me he’s getting numerous pairs of Veritas back as trade-ins that he’s doing complete inspections on and reselling for about $5K/pair.
My requirements for a preamp are at least two balanced xlr inputs, at least one balanced xlr output, a convenient HT passthru capability, a precision volume control with 1db or less adjustments, under about $8K used and a good remote.

Option#2. For a total of about $12-$14K, buying a pre-owned Mola Mola "Suite" consisting of a Makua preamp and a pair of Kaluga mono-blocks.

     Both of these options are about 50% less than new and I’m currently in the middle of my search for units in very good condition and with a current preference for option#2. Unfortunately, I’m unable to audition either option in my system but I’m looking for dealers or individuals, within about a 100 mile radius of Indianapolis, who may have any of this gear available for demo and purchase.
     My goal is to purchase within the next month. I’ll also have a Parasound Halo P6 preamp w/remote and a pair of D-Sonic M3-600-M mono-blocks, both in very good condition, available soon for purchase at very reasonable prices if anyone’s interested.
