Old Sony changer finally died. Need a new one that will run my 4425s and L-7s. Unit has to withstand bass from being in the middle of center firing L-7s woofers and not cost an arm and Leg. Any input would be welcome. A smoother tube sound might be nice, but I really don't want to change tubes every three years, plus I live in Tucson so heaters, even nicer sounding ones, are not welcome in the desert.
Thank you for your input.
Don
