i am willing to try attenuators but are they any more effective than the front panel level controls? which are variable resistors, no?
Too Much Gain the Issue ? (preamp and amp)
I have a Cary SLP-05 preamp- 24db gain with balanced and 17db single ended.
Using a Pass Labs XA30.8 (26db gain) and even with the 17db of the single ended output of the Cary preamp the sound can frequently be sibilant in the upper midrange.
Have not had the sibilant sound with other amps (Parasound JC5) but did lower the gain on that amp to 50% of dial.
Thanks.

You have a tube preamp and I am the only one advising you to roll those tubes 😂 I believe these preamps ship (at least they used to) with Electro Harmonix tubes which are great to liven up a dull/dark system but could very well be a bad match in yours. Adding attenuators can lower the noise floor but won't help the main issue you cite. |

@mulveling +1 on tube rolling definitely worth exploring Also, in my experience, rarely anything is a “direct replacement” when it comes to swapping components in the system that’s been tuned over time to have a specific sound. And introducing a different amplifier is not a small change. I won’t be surprised if you might need to work with speaker placement and toe in as well as revisit the cabling. |
