Love / Hate relationship with vinyl?

Ok, I do love the sound of vinyl, but with my LOMC (Lyra Kleos), I hate the noise (low level hum, and hiss) levels I'm getting. I own a Hagerman Piccolo head amp that I haven't used in a couple of years, so I thought I'd hook it up, and see what happens. Well, still got the hum (at high levels), and the hiss. However, I do like what it's doing for the sonics! I've tried moving cables, moving the head amp, but I only get incremental improvements. Is this just the nature of the beast (LOMC's), or is there something I'm not doing that could improve these noise levels? Of course, another option is to go with something that has more output, like a HOMC, of a MM? Thoughts?

To answer Swampwalker above:
Thanks for the info about the KAB calculator.
Also, I have tried the lower setting on my phono preamp, but then I have to turn up the gain on preamp, and thus the noise.

You said how can you check the turntable motor Is the hum and hiss always there? Even when no record is playing? If it is there only when the turntable is playing then at least the hum is coming from the motor. By the way my system is dead quiet with no ground at all from turntable to phono amp tp pre. You could also use some 3 prong to 2 prong power adapters and float all the equipment

To all:
I'm beginning to think that because I'm hearing mostly hiss, that it may be the tubes in my Audible Illusions L3 preamp. I bought the preamp new Christmas, 2012, and the tubes are still the original tubes. Going on 3 years now. Time to order some new ones (only two - 6922 variety).

I don't know how to fix the hum but having hum is completely unaccepatble. The system should be dead quiet when operating optimally.

Louis, my TT is a hot rodded Classic "2.5." IOW, It's a standard Classic, but with a (i) Classic 3 stainless steal wand and tone arm base, and a (ii) Classic 3 motor (300rpm). That's it. I have no hum problems. And, as an fyi, I didn't have a hum with the stock motor (60 rpm) either. Doubtful that the hum is coming from the Classic motor.

And yes, old tubes can act out by becoming noisy and hissy. Freshen up your tubes, especially in you phono pre and linestage.

Some of our other members might have some good suggestions about the hum. In the meantime, freshen up the tubes and report back.

Cheers,

BIF
