Luxman SQ-N150 Integrated Tube Amplifier

I use my Little Luxman successfully in a small 12’ x 12’ office, for streaming usb out of PC to DAC rca out; reel to reel tape; and vinyl with 

AT440ml, which has a strong 5mv MM signal

Your 500 is only 3mv; the 200 is 4mv.

My speakers, AR-2ax are 90db; far lower than your 97db

I truly enjoy having tubes in a small space with not much heat, and enough volume, but it is not enough for a larger space, especially starting with a weak signal.

I did hook it into my main system when I got it, it played my 16 ohm horns/15" woofers, but they are more efficient than the Volti’s, in the 100’s I suspect, and I never considered keeping it there, just to hear it in a familiar system.

It's the best sound and Imaging I ever had in my office, everyone who hears it is equally impressed.

faustuss,

Digital input meaning using digital sources CD, DAC Etc to the line-in. Yea, everything we did gives the same results. Low gain 

Definitely an oversight on Luxman's part to be forced to use specific cartridges unlike Nagaoka's which are popular choices. 

Are you saying that you cannot achieve good vinyl sound even when the volume pot it turned up more than the digital source?

I was on the verge of buying this amp several times. But it's just too underpowered in every aspect. I guess a good bedroom choice with thin walls and sensitive speakers.
