Hello Guys.
I was hoping someone can shed light on why my Final Audio Fi BA SS and AKG 3003i sound so much fuller via my Iphone or AK100 than via my Desktop rig with Slee Solo Ultra Linear amp? The Slee has no noise issues with the IEM, in fact it is dead silent. It is said that it was designed with IEM usage. With all the IEMs it sounds quite lean. When using my Audeze or Fostex Headphones it sounds great with full tones!!!!!
Forgot to mention that my desktop rig consists of Lampizator transport and Lampi DAC going into the Slee.
Do all IEM sound better via portable devices or portable amps?
The Slee Solo specs are
Power output: (rms, both channels fully driven at 1% THD)
32 Ohms: 140mW/channel; 600 Ohms: 30mW/channel
Input sensitivity (for specified power output into 32 Ohms): 511mV rms
Input impedance: 37k Ohms at max volume; 50k Ohms at min volume
Distortion: (THD plus noise at 9 o'clock volume control setting (qtr power))
10Hz-20kHz: better than 0.04%; 10Hz-1kHz: better than 0.02%
Frequency response (±0,-3dB) 10Hz - 35kHz
Output noise: (22Hz-22kHz, quasi-peak/un-weighted) -95dB
Channel balance: better than 1dB
Crosstalk: Left to Right -56dB; Input to Input -68dB
Input selector centre-off position: non-shorting; -38dB at max volume with 2V rms input (ref: 1kHz and 10kHz)
Output Stage: Bipolar class AB
Supply voltage: 24V DC unipolar
Size: (approx.) W: 107 x H: 50 x D: 185 (mm) inc. controls
