Ipar 1023A Tube Pre Amp / Headphone Amp Review From China

post #1 of 5
Thread Starter 

This amp I got it for around US$110, it has 4 pair RCA input with 1 pair ouput, 2 volume control, 1 for Preamp, 1 for Headphone, s/n ratio for preamp was -113db while head amp was -114db, technically details I did not really concern, but the sound it produce were supreme and musical, I had connected it with my Nuforce STA-100 power amp and iFi Dac with same brand USB power, after my fully testing and compare with 3 others preamp (Technics battery drive SU-C1000MK2 / Adcom GTP-450MK2 / Audiolab 8000C), the conclusion was outstanding, soundstage preformance was really suprise me, dynamic, warm, wide, details, and musical, inside built quality was similar to Nagra, of course Nagra use more better parts.

the tube inside was use for buffer and it was come with a GE 5670 tube, I am planning to replace it with Western Electric 396A, usually when I brought a China machine I will immediate throw away the China tube but this time I did not, the sound re-produce was so attractive to stop my intention, too good to be true at this price, really worth to try.

Found this amp on the Valab website and it looked interesting. Glad to see a review here. Do you have any new impressions now that you have had it for a while? It appears to be well made and the price is right, satwilson
