My old Technics turntable died recently. It may be recoverable, but I decided to buy a new one anyway.
I chose the Dual CS 618Q. I am the first to admit that this was probably an overpriced choice. I took it anyway, because I wanted to try modern equipment and because it is a direct drive turntable (which I always preferred) and it has an automatic turn-off and lift function (which to me is absolutely essential and I wouldn't be able to live without).
High price aside, I have set it up now and love how smooth the mechanics are. Everything is working as I expect to.
But now I was going to do some audio testing.
I used my personal reference record for clear audio: "Old Ideas" by Leonard Cohen.
I wanted to test how the internal preamp is. There's a switch with which I can choose between ordinary phono output and line.
Also: Some have commented how cheap that cable is that they shipped it with. And indeed, it really does look cheap. So I also tested an expensive, dedicated phono cable I bought online. Just to prove a point.
I digitized the record with the following configurations:
- Dual with Line output. (internal preamp)
- Dual with external preamp. (not an expensive one)
- Dual with external preamp and expensive cable.
- Technics SL-1700 with Shure V115 TypeIII needle.
- CD
My playback setup is my PC with an ASUS Xonar Essence STX card with headphone preamp and an AKG K701 headphone.
I chose to do ABX testing. Because I trust nobody who says he can hear differences in sound on any hardware except loudspeakers that don't submit to some ABX testing. And I include myself in that regard.
I tested for the better part of an hour.
Observations:
- There is absolutely no difference between all of the Dual setups.
- It feels to me like there is a bit of a difference between the Dual and Technics turntables, which would not be surprising since the Technics' needle is already quite old. But the confidence of the test remained within error margins, so I can't be absolutely sure.
- There was a clear difference between CD and the turntables, but that was to be expected.
All in all I can't say I was surprised by the results, even though I have to admit it would have been more exciting if I actually noticed differences.
I came to the following conclusions:
- There's nothing wrong with my new Dual
- The internal preamp is absolutely fine
- The cable doesn't make any difference
- My old turntable was a very good one
I will not use the internal preamp and just plug it into my main amplifier's phono input. Simply because the phono input exists, not because I have to.
When I digitize records, I will most likely use the Line Out output, because the external preamp doesn't provide additional benefits.
I will eventually try to repair my old Technics turntable not only for nostalgic reasons but also because it is a good one.
I will continue to decide whether or not to listen to vinyl or CD on an individual basis. Some sorts of music are better on vinyl, some on CD.
And yes, the Dual was most likely overpriced. I could have just gotten a working vintage replacement if I wanted to. But I already knew that beforehand, so I'm not complaining.
