Sota Big Monitors..

Jay, thanks for your thoughts, my amp has hefty power supplies
though it is parallel single ended using three kt88 per channel it reacts as if 2x100 watts comparing many ss amps
besides I met many SHL5 owners who use tiny ss integrateds
or 2x30 tube watt amps with them (I know the other models of
Harbeth especially M40 need real high current but SHL5 is a bit different I think?)
As for my search for monitors, I am looking after best midrange and soundstage which monitors could give to me supporting with a subwoofer the low bass range 15-30/40Hz
where as most floorstanders you sacrifice the glorious midrange and soundstage for the sake of low bass band so that
the manufacturers try to produce all in a package except
some models 25-40K priced.
Could you please explain why SHL5 could not fill my large room ? (with subwoofer) if you have heard them.
Thanks again

Jond, thankyou for your comment, you are right JM lab makes serious speakers,however my speakers (Neat Acoustics Ultimatum MF7) use their tweeter and they are comperable sound beauty,
but I am searching some thing special maybe, the midrange like
Quad 988, I mean I am a bit tired of modern sound reproduction
of well known brands and one can find many speaker which excel
top and low frequencies easily but the music is another story.

Audiokinesis, I really thank you for your detailed recommendation, I will check deeply Gedlee Summas
I am just curious they will work in my large room? as its white paper explain how well they work in small rooms but
nothing written for large rooms?..
