Will Changing my 100 Watt Tube Amp to a 200 Watt SS Amp Solve My Problem?


Hello All,  I have a 100 watt Audio Research VT100 mk II amp, with an Audio Research LS-25 preamp.  My speakers are relatively low in sensitivity, and I find that I must turn the volume up to 3 o'clock on the preamp to get enough volume for a loud listening experience.  When I do that, I am introducing more background noise.

I would like to achieve a quieter noise floor.  I am also curious about the limits of the 100 wpc amp with the Mira Monitors.  Would an older Krell 200 watt class A amp "control" the speakers better?  If so, what are the benefits of this?  There are a few amps on this site that caught my eye, all about the same value as my amp, so I can potentially make a move with very little cost.  Is this a good idea? How much wattage increase is necessary to get a significant enough difference?  Would a jump to 150 watt solid state be sufficient?


here are the 3 amps that caught my eye:

A good high current amplifier ,a 250 Pass labs is a nice choice Plinius,
Even better Vitus,Gryphon ,depending on your budget,son of Ampzilla great buy
Good luck let us know what uou do.there are many good products out there.
I owned an LS-25 and the 200w version of the amp, but also heard the VT100 with it....should have a gain boost on the preamp...should give you plenty of gain unless something is wrong?
The Job 225 amp has an input sensitivity of .75v and gain of 35db.
Problem solved?
