Juansan2 Posted January 13, 2022 Report Share Posted January 13, 2022 (edited) 2 hours ago, Kung said: it seems very odd，do you mean that the sound of 007 is different after 717 modification? for all I know，only 727 negative feedback modification, never heard of 717's（CCS mod?），717 is pretty a kgss and should be no problem driving 007. Providing headphone frequency response or some amplifier tests should make it easy to find the cause of the problem.😶 I had never heard the 717 unmodified at all. This is my first experience with it, purchased about a year ago from Spritzer/MA and I’m pretty sure it’s not the amp itself. Frankly it is absolutely sublime on everything except those few remastered Vangelis albums but which sound ok on my other gear, in particular the album spiral, so I am a little perplexed. If I play them quietly on the 717 they sound fine but if I increase the volume (from my DAC, not the actual 717) to a level equivalent to other tracks that I listen to, the Vangelis albums start to sound hard, compressed, glassy. I’m not sure why, it could be that they are excessively compressed as recordings, but then I don’t understand why they sound ok on other gear. Maybe it is because the 717/007 combo is so revealing that it is showing up potential over-compression of the recording which not even the kse1200s show. Just wondering if it was a known phenomenon that certain types of tracks can do that 🤷🏻♂️ Edited January 13, 2022 by Juansan2 Quote Link to comment Share on other sites More sharing options...
