UPA-2 vs. UPA-200

[zekeblue]

Sorry if this has been beaten to death. Could I get some opinion about any advantages of the UPA-2 vs. the newer UPA-200?

Many thanks........

Here is one difference:

UPA-200
Power Output
(rated power; THD < 0.05%):
125 watts / channel (8 ohms; all channels driven).
200 watts / channel (4 ohms; all channels driven).
Rated Power Bandwidth (at rated power; 8 Ohm load): 10 Hz to 20 kHz + / - 0.1 dB.
Minimum Recommended Load Impedance: 4 ohms (which equals one 4 ohm load or two paralleled 8 ohm loads per channel).
Frequency Response: 5 Hz to 80 kHz + 0 / - 2 dB.
THD + N: < 0.03%
Signal to Noise Ratio (8 Ohm load):
> 92 dB at 1 watt (A-weighted).
> 106 dB at rated power (A-weighted).
Damping Factor (8 Ohm load): > 500
Speaker Output Connections:
Full-sized 5-way binding posts; one pair per channel x 2.

350 VA high current ultra-low noise toroidal power transformer.
40,000 uF of storage capacitance.

UPA-2
Power output (all channels driven):
185 watts RMS @ 4 ohm (0.1% THD)
125 watts RMS @ 8 ohm (0.1% THD)
Power Band Response: 20 Hz to 20 kHz with less than .05db deviation at rated power
Broadband Frequency Response: (]3db): 5Hz to 150kHz
Amplifier Gain: 32db
Signal to Noise Ratio 1 watt: >93db Full Power: >107db
Input Impedance: 25kohms
Transformer Size: 300VA
Secondary capacitance: 40,000uF
