What kind of a amp needed to drive t60rps?
Per Fostex it will do 93db/milliWatt therefore 103 per 10 mW, 113 per 100mW and 123 per 1 Watt and almost 128 per 3 Watts.
In addition Fostex states that it will easily handle 3 Watt. I have taken it out repeatedly to 5 Watts.
Music is 90db and background Hall noise is 30db for a total of 120 db in classical music concerts (these are momentary 5msec peaks
the average or RMS values are typically 30 db lower) in rock concerts where there is lots of background noise, peaks approach 140 db
airplane take offs are 130+ db continuous (RMS).
The ifi Micro IDSD will deliver approximately 2 Watts into 50 Ohms and 4 Watts into 25 Ohms and thus will drive two Fostex RP sets
to Nirvana if an ifiUSB NANO (200$) is used to filter out the noise from the hardware and software from the PC or MAC coming though the USB cable.
IF state of the art software is used the Fostex will Kill most all 2000$ headphone sets.
1) Audirvana Plus (100$)

2) JRiver 25 64K bit version (50$)

3) Tone Boosters (Free)

4) Sonarworks Reference 4 SystemWwide. (100$)

44KHZ Waves or Flacs can be converted to DSD by JRiver and rendered by the Hires DAC of the Ifi MIcro DSD (450$).
The end game system for a Music-phile is 300+200+450+250= 1200$
or instead of PC or MAC a Walkman ZX300 and no need for the ifiUSB NANO.
The key word being Music-Phile and not Audio-Phile.
In My Own Opinion and my friends Music Professors, Musicians and Record label producers that have blind tested them against the sets I owned in my profile..
End of my Audio phile lifes story.
