I got my pre amplifier about 10 days back . The sound quality was good, especially when the volume knob was beyound 9 o'clock position. However I had some problems.
I rarely needed volume knob to be turned beyond 8 o'clock position due to high sensitivity speakers and at this level, the pre amp was giving inconsistent signals to the left channel. The signals were well balanced beyond 9 o'clock.
The volume knob was too loose for my liking with instability in volume control. According to Mr. Bajaj, it was due to remote control motor assembly. So I sent the pre amp back and got the remote assembly removed. The volume knob was no more loose and that issue was resolved but not the inconsistent signal to left channel. I also noticed that
1) Even in switched off position, the pre amp passes some signal to power amp (loud enough to be noticed when standing close to speakers). The volume knob increased the volume even with the pre amp switched off. At 10 o'clock position, I could very well hear the song albeit very much distorted. The sound was never distorted when the pre amp was switched on.
2) When switched on, I could easily hear music even when volume knob was at Minimum position.
I was not comfortable with it because my speakers have high sensitivity (98db/w). May be this problem will not come if speakers have sensitivity less than 90dB/w. Mr. Bajaj told me that these are not major issues as such but could not be rectified. So I had to return the preamp.
It was a pleasure to deal with Mr. Bajaj with prompt replies and he was frank about this product.
