Legacy Audio Impulse integrated amp (200W/Channel SS amp) - low volume issue

Hi,

 

I recently bought used Legacy Audio Impulse integrated amplifier locally, There is not lot of information online but it was mentioned that it was built by Coda technologies for Legacy audio and its 200 W/ channel in 8 ohm and 400 W / Channel in 4 ohms (so Similar to Coda Csib int amp).

I used this amp to drive ProAc DR40R as well as Audio Nirvana high efficiency speakers, The issue I am experiencing is that I have to increase volume quite a bit for decent volume level (it goes from 99 —> 0 and I have to increase it to 35, to listen to decent volume.)

My other two amps combinations

 

1. Musical Paradise small tube int amp MP-301 (6.5 W / Channel)

2. Aric audio unlimited preamp + Digital Audio Company class D Cherry mono blocks

 

Are more louder at lower volume than higher volume on Legacy audio Impulse integrated amp (200 W / Channel SS) which is really puzzling.

 

Just wondering what could be the issue with the amp, Why do i have to turn the volume so high ? There is hardly any documentation available online so no manual is available to troubleshoot.

 

Any feedback is appreciated.

 

Thanks,

Thank you stereo5, Valinar, mulveling, I am not worried that much anymore, l am getting same feedback from you all that it could be Gain may be because of the passive preamp section, and its quite normal behavior for this amp.

I will keep it in the 2nd system, meanwhile i compared it for little bit with the tube preamp and class D mono blocks and I still prefer tube preamp (with NOS Mullard) + Class D mono blocks but may need little longer comparison.
