Are you looking for a DIY setup? In case, I might lend a hand (I like to diy)
My suggestion, on a diy Setup point of view :
1. you will need a DAC for USB and/or Optical (SPDIF), this is better than using your PC sound card with the 2.5 mm jack output, if your PC have similar good audio interface, then you don't need the DAC,
2. You may need a tone control or EQ (Equalizer) to tailor the sound quality you are looking for.
well, depend on your speaker and environment (some DAC included EQ and/or Tone Control)
3. you may need an amplifier with power up to 15W at least, better with 30W or higher ---
average power, to avoid your amplifier to clipping" specially when you desire for bigger
sound output
4. Speakers --- the selection of speaker can be Full Range dual cone or 2-way with dividing network
Let's say, 2 -way speaker, this can cater most music and with a better bass response (I believe)
than full range itself
Board level :
You can get #1,2,3 as separate board and you assembled by yourself -- adding the power Supply
this is most diyers do with a customized casing
for #3, since you specifically like Class T (I supposed Tripath chipset), you may try the TA2022 with reserved power up to 90W/channel at 4 ohms.
Finished Product :
There are DAC+Tone Control + EQ + Class D packed into a s mall chassis, I guess it can satisfy most of the user, including me
If for DIY modular board, let me know your choice and i might can send to your home direct from China, while I am here -- while really here now!!!! (but need to escape the custom in Manila or Clark)
