Does the REL have an internal amp?
Regardless, There is a Rogue Audio Sphinx v2 integrated on Audiogon now for $950. These units have " Tube driven active outputs for subwoofer" . Add a modestly priced DAC (like a piece of Schiit) and you still got 8 or $900 for Speaker choice. Then after time you gots the flexibility tube roll and upgrade the DAC as DSP technology progresses.
