Ssssh, is your tube preamp really that quiet?

101 db Zu Definition 4 with an Art Audio dm VPS tube pre amp and Art Audio Carissa 16 watt SET tube amp- not a hint of noise at full volume, ear at tweeter, with no music playing.
I suspect tubes? As mentioned above, try rolling your pre amps tubes. I have had noise in the past but corrected this by simply removing a noisy tube.

THORESS preamp very quiet!!

ARC sp16 is very quiet when all tubes are working well. One might be hard pressed to know it is a tube device just listening. Surprises me in that regard all the time.

Phono section is a tougher beast to keep quiet, but it is not a problem with the right especially quiet tube in slot 1.

When choosing tubes, for a pre or phono section; it's
imperative to seek out those that are tested, and certified,
for that purpose(Low Noise). Of course; your provider has to
know how to properly screen valves. ie: Upscale Audio (

Tubes.html ) However; when you crank your volume to full,
the pre might not only let you hear tube microphonics, but
anything that interconnects, or empty inputs, may be picking
up(ie: EMI/RFI). If there's a phono section ahead of it;
it's noise is amplified/compounded.

With my McIntosh C2300 with Tele smooths in the MC stage I only here tube rush with volume on +75 (out of 100). The line stage is hush quiet.
