Introduction
I remember when I first got into vinyl blah blah roy gandy is a swell guy.
The Story
While the DL-103 > Cinemag SUT > Bottlehead Seduction sounds great with rock recordings, I've been experiencing some brightness when listening to certain jazz records which I know aren't mastered bright (Hoffman 45s).
After trying to do everything I could with my speakers (move to and fro front and side walls, toe-in), and confident that my cartridge is setup perfectly, I remembered something I read about cartridge brightness usually having to do with loading. Looking up the impedance of the Seduction, I found it is 47K ohms. The recommended loading for the DL-103 ranges anywhere from 100-1000ohms, or sometimes higher, depending on who you ask.
"If only I had a phono stage laying around with lower impedance!" I proclaimed loudly to myself. But wait, I do! My Bugle was built to mate with the DL-103, with a gain of 60db and loading of 470ohms. You might recall that I complained about large amounts of hiss when I used the Bugle previously. However, in that case I was using headphones or near field speakers. "Perhaps now that my speakers are in a larger room, the hiss won't be so bad! Besides, I get an opportunity to at least see if loading is truly part of my brightness issue," I again declared to myself.
So I took both the SUT and Seduction out of the equation, and ran the DL-103 straight into the Bugle and then on into the 840A. The result is significantly less brightness! And this Bugle really is a hell of a performer. It handled that subtle jazz midrange well, and completely rocked the bass on Black Cow. It gets everything on Ryan Adams' Gold just perfect. I'm seriously impressed by this amazing little unit. And as far as the hiss goes, yes its there, but in my current setup I only hear it inbetween tracks, and there it is not unpleasant at all. Its more like mild tape hiss on a great sounding recording, rather then an annoyance.
So luvdunhill is correct: the Bugle rocks!
So lowering the loading impedance made jazz less bright, and made rock even more silky delicious smooth, without taking away any of the musical "bite" of the DL-103 that I'm so hooked on. I'd love to try the loading all the way down to 100 ohms, and maybe I will if I ever pickup something like the Rogue Stealth.
Tonearm Mass Loading Sidebar
Encouraged by my success with the Bugle, I decided to try a tweak recommended to me here by Torpedo. I didn't have a pretty way of increasing overall tonearm mass, so I scotch taped a penny to the top of my headshell (someone please tell me if this is a bad idea). I tried two pennies, but then I didn't have enough counterweight to get the VTF back to 2.5g.
The result is, I believe based on early listening, increased bass and dynamics. Pretty awesome. It'd be nice to find a more permanent solution, maybe something I could put between the cartridge and the headshell.
Disclaimer: I'm no vinyl expert, having only been into the stuff for a scant 18 months. I would greatly appreciate any technical corrections more knowledgable folks can provide, when I get into the realm of ohms and such things can easily end up over my head.
