Anyone who owns a Technics SU-R1000, can you answer a quick question


I’ve been getting familiar with the new SU-R1000 for the past couple of weeks and I’m thrilled with it so far. Selling all my other gear, sounds amazing, couldn’t be happier and all that jazz.

But I am wondering if anyone here who owns one can answer a question about the phono preamp noise floor?

Stereophile measurements appear to be impeccable, but I hear a definite noise floor in the phono pre, even when the source is turned off. It is a hiss that is inaudible until the unit is turned up much beyond 40 on the volume knob.

I have swapped out my Pure Fidelity table with my Technics SL-1200, optimized both cartridges, and both have the sound. When the amp is muted it mutes the sound.

It is not audible on any of the other inputs.

So if anyone else has this preamp - could it be mine has a defective phono pre input, or is it just a higher noise floor?

Hard to guess with no information on your cartridge or phono amp setting. What stands out to me is that you have high efficiency horns and that might make the built-in phono amp stand out. That's why most prefer a separate phono pre-amp with gain and load adjustments. Your phono amp probably has more gain than you need (or want).

Thanks, sorry I wasn't more clear. 

My question pertains specifically to the SU-R1000's internal phono preamp, specifically to anyone who may own one and can tell me if they have a similar experience. 

I am moving from a Parasound JC3+ and separates (Backert Labs Rhythm, Luxman M900u) so I have never had noise floor issues with the Parasound or any other phono pre - external or internal. 

The R1000 has some signal DSP processing internally on the phono pre that may make the noise floor higher - it hasn't been mentioned in any reviews and doesn't appear in the measurements so I'm concerned my unit may be defective.
