Hello, not sure how active this thread is but I do have some questions. I am pretty well versed in the game of high-end audio however I recently made the leap into the world of vinyl.
I purchased the Pro-ject Debut Carbon DC and of course needed a pre-amp. I have a few scattered brands of headphone amps and DACS but always wanted to try a Schiit product so I thought buying their pre-amp would be a good start....and so I did.
My first attempt at playing a record had a significant amount of noise...like so much I couldnt even enjoy the music much at all. I tried about everything positioning-wise between my 3 devices( tt, pre-amp and headphone amp) and could not get the background noise/hum down to any acceptable level. The oddest part was that the noise was way stronger on the right channel than the left. very odd. I messed with my grounding wire, messed with the RCA cables...nothing.
A couple of days later I was doing more research and found out that the cables provided with my TT could be the issue, so i swapped them out with some cheap but somewhat well made monoprice cables. And i do feel this made an audible difference in the noise, and I certainly am not noticing the channel imbalance with the noise any more.
However, the noise was still present so I sprung for a audioquest evergreen cable to connect my TT to my mani. Listening for a few minutes today, background noise is at a possibly acceptable level but there was some odd pops/crackling I didn't notice before with these cables.
All of what I describe is heard with the tonearm up, and sometimes with the RCA's between the TT and mani even disconnected entirely, and turning up the volume on my headphone amp to about 40%.
I guess my 3 main questions are,
1. Is a certain amount of noise floor just accepted when using a TT? Impossible to reduce? I also, have a at-lp60 with built in pre-amp and I just dont remember this amount of noise.
2. Is there anything I can do on my part to reduce the noise? Location of devices/grounding/power filtering?
3. Is this amount of what I hear acceptable of the Mani or is this a bad unit? or perhaps upgrading the power supply would help?
I really do not think the Mani is defective, when I was hearing way more noise/hum from the rt channel than the left I thought this to be the case but since it is the same from both now and reduced I believe this probably "normal."
Again as I said, I'm not an audiophile when it comes to vinyl so this is all relatively new to me. Just trying to get the best sound I can and reduce some of that noise during playback, especially during the more quiet/intimate parts of songs.
Thanks.
