Class D is just Dandy!


I thought it was time we had a pro- Class D thread. There's plenty of threads about comparisons, or detractors of Class D.

That's fine, you don't have to like Class D amps, and if you don't please go participate on one of those threads.

For those of us who are very happy and excited about having musical, capable amps that we can afford to keep on 24/7 and don't require large spaces to put them in, this thread is for you.

Please share your experiences with class D amps!

Hello listening99,

     I’m not quite sure who you’re directing your question to.  If it’s me, I don’t think I’m the best individual to answer your question.       My experience with class D amps has mainly been searching for ones that best drive my former Magnepan 2,7QR and current Magnepan 3.7i main speakers, which are both only about 86db@ 1 watt and much less efficient than your 98db@ 1 watt Tekton Moabs.     The best amp I’ve ever used on my speakers are a pair of D-Sonic M3-600-M class D mono-block amps.  But these amps output 1,200 watts into my 4 ohm speakers, which seems excessive to me for your 4 ohm speakers.     Unfortunately, I have no experience utilizing high efficiency speakers since I was 18, 44 years ago. Therefore, I have very little useful knowledge to share with you except I believe you don’t need to exclude any amps or amp types from your search. Hopefully, you’ll receive some other lower power suggestions from other readers of this thread,  
Tim
     
Listening99 the criticisms I saw of the vtv amp were just nitpicking.  Their prices are the best, they use nice thick cases sourced from Ghent and it’s in the USA so no customs worries.  It’s a good deal.  If you’re worried about pcb and wiring layout, apollon in Italy is known to be good with that.  But they use cases sourced from hifi2000/modushop which are kind of thin.  I came super close to getting a purifi amp from vtv but I realized I have way too many unused amps in my collection as it is
Thanks for the reflections that might help me dial in my speakers/system from an amplification angle.

So, this is where I am (1): just bought and have been using the XTZ A2-300, which runs off IcePower. Amazingly, the sound signature is NOT much different from my NuForce STA200. It may be, in the Nuforce, that the midband is slightly more rich, more lustrous, but in normal listening, where I’m more into enjoying than critiquing, the differences quickly fall away.

The new XTZ runs cool, supplies more than adequate juice (up to 470@2.7ohms), seems to provide a little more shape to instruments within the soundstage than the Nuforce. For instance, the dimensions of the drum set in my favorite ’instrument’ reference CD, Harry Connick Jr’s "Lofty’s Roach Soufflé" is more realistic.

I’ve also noticed micro-dynamics from the XTZ that seem a little more glossed over in the Nuforce. Unfortunately, I think there are huge psychological impacts that arrive with a new piece of gear, and the mind/ears are more vigilant and likely make a bigger deal over presumed new discoveries that might have been equally attractive if someone had fooled me and placed my previous amp in the chain before playing a song I have been cycling for the past several months.

I'm all too familiar with my enthusiasm for the new sexy thing that arrives in the post and how that enthusiasm carries me through the opening phase or two with that sexy new thing.

So, here is where I am (2) ... I’ve paid $500 for the XTZ. It’s great, no problem. However, I know it’s definitely a bargain audiophile product and while it is amazing for the money, I’m wondering if anyone can speak to how IcePower compares to the Purifi module, or the Hypex modules, or Pascal.... I mean, if I can pay an extra $1000 or $1500, would I hear substantive improvement in soundstage, tonal accuracy, vocal purity, etc., or am I just about ’there.’

I know it’s only I that can say for sure, but have any of you studied the differences between these amps and found significant distinctions from one modern class D amp to the next?

Thank you,
Just got my PS AUDIO M1200 monos this week probably will be trading my Nord One Up monos with Rev D input boards in on them unless someone makes me a good offer on them
