Anyone modded a Steelhead?


Besides rolling the tubes,which I've done,has anyone swapped out any caps (which ones/where ?)or done any other modding to this nice phono stage?

I run mine directly into my power amps(tubes),but I feel I could use a bit more fullness.
What I don't want to do is run it into another pre-amp, there's just too many wires and circuits to contend with to my way of thinking if I went that route.

I should add I did upgrade to a HiFi Supreme fuse and this positive experience leads me to believe there might be some other parts in the Steelhead that could be improved.

I had a Steelhead for approximately 6 years that I bought new. I used a variety of NOS tubes, very good power cord (K-S emotion) and experimented with the different inputs and settings. The best results were obtained by using it only as a phono stage, through the fixed outputs, with a good quality line stage (at the time, a Lamm L2). I also preferred the MM inputs to the step-ups on the two cartridges I was using: a Lyra Titan i and an Airtight PC-1. I found that the addition of the line stage gave more weight and palpability to the sound; the Steelhead straight in had great bass and high frequencies, but sounded almost threadbare. Granted, I may have been adding an additional layer of cables and signal processing to the chain which is, in theory, not a 'purist' approach but that was my real world experience over the long haul, and not just a fast try-out of the piece or hearing it in someone else's system. The 'lack of meat on the bone' is precisely the difference I am describing, btw.
Lacee- I'll be interested to know if using the Lightspeed in lieu of the
volume control on the Steelhead is an improvement. (I'm aware of the
Lightspeed but never used one). Perhaps the difference in sound I
experienced between fixed and variable has to do with how the volume
control is implemented, I don't really know. I did find a considerable
improvement in tube rolling- the Sovteks are pretty sterile sounding; in my
system, i liked the NOS Tele the best, found the Mullard to be too euphonic
and the Siemens to be a bit stark. I also rolled the 7044 tubes. I've had
wonderful experience with the K-S cables, including power cords, though I
know that everyone has their favorite, depending on a variety of factors.
Two other observations: first, doesn't the mono switch still work even if you
are in fixed output mode? (I can't remember); also, my comments re the
sound 'straight in' were going to a pair of Lamm ML 2 SET amps, which are
very musical, with lot's of harmonic texture. So, it isn't just 'adding more
tubes' that makes the difference.
