So I currently am running a Laptop > AudioQuest Jitterbug > AudioQuest Forest USB > Topping D30 > Audioquest Forest RCA > Topping A30 > Headphones it sounds good, but i honestly want to run my setup through SPDIF instead of USB for now on. No good reason really! Maybe just an excuse to spend more money? So, would i be able to throw a 'Shiit Eitr USB to SPDIF converter' into that lineup? I was told chaining the AudioQuest Jitterbug with another Jitterbug would cause the sound quality to get worse. Will adding in the Shiit Eitr cause the same malfunction? If the Jitterbug did cause the sound to get worse if the Shiit Eitr was installed then I could just not use the Jitterbug. But It would be in my best interest to use all audio equipment i have purchased rather than just have it sitting in a drawer. Any one have experience with this?
