You are only teasing yourself with the tube DAC.You simply haven't experienced what tubes really bring to music playback until you go tube amplification!!!
Your speakers have an easy 8 ohm impedance,with a min.of 7 ohms & a min.recommended power input of only 11wpc.so you can get into a SERIOUSLY good amp in your budget range.I would look at the Ming Da MC368-B902"Piccolo",the iFi Audio "Retro Stereo 50"(my personal amp) or Yaqin "MS-30L"(IMO the worlds BEST remote control)with NOS 6AK5 tubes in the front, some ReIssue EL34's in back & running in Triode Mode...If you have a BIG room go with a Class A Push Pull(like the MS-30L)or one of the new Triode Strapped KT120 amps.ANY of these amps will put you into a completely different realm of music playback...
