I already had the integrated receiver Hitachi sr 904 ... Great amplification for my Hifiman He 400 out of the speakers taps and for my Fostex TH7-B in the headphone out, better for me than my good Ember... I am curious if someone here know about that amplifier... i deoxit all the controls... and let them dry now... i bought the amp+preamp Sansui AU 7700 from the first owner (1976), it seems in very good shape, he dont use it for decades i think or sparsely between decade of non use , stored...with the money spared because i dont need to upgrade ( i already had an extraordinary dac : Bushmaster MK II +upgrade and extraordinary headphones,) for a long time to come, i paid it 150 canadian dollars (75 pounds )... If someone had opinions and advise ...I will be all ears to you...
i deoxit all the controls today... i will stat it up this week good week to all
