I think the RS2i will compliment the PS500s for my taste. Sometimes, I miss the forward presentation of the 325is. The PS500s mids and highs are clear, but it is a bit farther away. I tried the RS1i and RS2i before, and I think the RS2i is a good match for the PS500s.
BTW, towel hook from ACE hardware... =)
I used to be a fan of Bose, until I discovered Grado and V-moda cans.
Still, I bought a Bose speaker since it is the cheapest one with decent soundstage. I have to always set the Itune equalizer to treble boost when using the Bose desktop speaker.
I am looking forward for a Little Dot tube amp. Either the Hybrid 1+ or the MKii ? I wonder if any tube can make the PS500 sound sig a bit warmer ?
