Discussion of Class D Amps Application & Experiences


With all the time off that our current situation has allowed recently, I became intrigued by the idea of class D amplification. I have always been against this type of amplifier but the more I have read the more I have also learned. There are lots of threads here on this subject many of which result in arguments about which amplifier class is better. I do not want to do that here. As I consider a class D amp I need to let you know that I currently use a fairly powerful class A/B SS amp and pre-amp into an efficient pair of speakers rated at 4 ohms. My choice of equipment has always been focused on musicality over absolute detail. I want the music to sound natural and not sterile. I seem to have achieved that sound. If I switched to class D amplification that would also be my intended goal although a bit more refined detail would be fine. I have considered pairing the amp with a tube pre to help achieve my desired sound. So why would I change? My goal would be to save money over my current gear while maintaining my desired sound.

I have researched brands such as Nord, Primare, AGD & Nuprime. I have also looked at brands such as Jeff Rowland & Merrill but those are way out of my price range. My target would be $6000 - $7000 or less. I'm about performance not price. So given that background information I would like to hear from those who have made the leap, what your experience has been (likes and dislikes), what amp did you replace and any comments about one brand over the other. Your experience with demos etc. Do you use a tube or SS line stage?
Thanks

I run the PSA S300 fronted by a Rogue RP-1 with Mullards.    I also acquired a DAC that was reviewed as having "warm" characteristics.  Did this for all the aforementioned reasons.   The sound is good enough for my needs.  I really like the way it fits into a tidy space and runs relatively cool.  It certainly has a volume level sweet spot.  I tried running it plugged directly into the wall vs  my Furman Elite 15 dmi and could not discern degradation with the Furman so thats where its attached. I use entry level PSA power cords and Marrow interconnects.  I would like try a tube or A/B amp some day but not sure I want to deal with the heat and power consumption.  I can't do much of a compare as my previous amp was also class D.   And PSA gave me a really good trade in for it.  So the S300 was Buck Bang for sure.
