I've been thinking for some time that this integrated amp could be excellent paired with my 94 db Blumenhofer FS2 SE. Now I use 2 Chord Etude in mono, I would like to change the "flavor". I've seen that a fair number of Levante amps can be found second hand at acceptable prices, perhaps the honeymoon has passed or could there be other explanations? This device intrigues me a lot.
 
Levante owners - do you have any hum/buzz (even the faintest) from your speakers when the amp is turned on and no music is playing? how's your noise floor with stock tubes or other tubes? my amp is now buzzing a bit with my Devore O/96 which are super sensitive so I'm wondering if this is common with the Levante design or I need to check my amp.

I have the Levante with a pair of O/96s and I have not noticed any hum at all. Could it be a grounding issue or perhaps the tubes needing replacement?

Thank you for sharing, I couldn't be happier with the pairing as far as tonality and performance go.
Unfortunately my amp's volume pot is now completely busted and can endlessly turn, sometimes it'll lock in with zero volume being at 11, moving backwards and max volume at 10.
Will send this to get fixed by the dealer.

When I had Devores and a Levante, there was definitely a higher noise floor vs. my solid state amp, even with my quietest source. Definitely tried some sources where it was quite noticeable. If you're hearing a 60hz constant drone....that sounds like a grounding issue.

i can’t say that I have experienced any noise despite using about a dozen tube sets. The problem could be grounding related. Has anything been changed before the hum arose?
