Hey That's Not So Bad if It's Class D


 So I don't have an amp right now & was fiddling around in the kitchen with music playing from my Samsung big screen when I realized the sound coming from the living room wasn't too bad...Bass had good definition but no depth or impact,drums sound like drums but again no impact,I can tell Slow Hands Strat from BB's Gibson & Greg Allman 's latter years rasp comes through with just enough gravel......There's no low level detail but I attribute that to the internal speakers..
Epiphany!!! I am most likely listening to a modern Class D Amplifier in the Samsung...If it is indeed Class D color me impressed enough to explore  the tech further....

I had the Red Dragon 500 mono amps and they were excellent. The bass hit harder with those amps than my Krell.
Hi there
I built a few amplifiers using PCB's that bought from AMAZON. It is important what chips are installed there. I like devices based on TDA7498 and TDA8950 and I don't like TPA3116D2. You must check it in their description. Also, the strongest power depends on the power voltage and if the tell you that output power can be 100W+100W and the voltage can be 12-24VDC you can get 100W per channel only for 24VDC. And one think more: highest power (say, 100W) produces 10% of THD or THD+noise. Good enough sound can be just to half of this power (50W for this case). Open my page in LinkedIn (Vladimir Benkhan). There are several articles there about high-quality sound.
I wish my Samsung put out about twice the volume that it does.  I consider this a huge weakness and am glad my stereo is integrated with it. 
I also feel All solid state amps can be improved with a good Vacuum Tube preamp. i have followed this practice  in 90% of my systems  ,
this too can apply to good digital.

Hello audioman58,

     A few years ago, I would have completely agreed with your statement but I now know it should be modified from ’All’ to ’Most’ solid state amps can be improved with a good Vacuum Tube preamp.
     I too used a tube preamp (a VTL 2.5 with NOS Mullard tubes) with various good quality class AB ss amps (Adcom,  McCormack and Aragon) for many years to warm up the midrange and have a detailed but smooth treble.
     I’ve since discovered that ss preamps combined with ss amps can achieve the same results if they’re both of high quality.
