Replace your speakers! At an abysmally low 86dB they limit you to high powered amps. Not that they will sound good with ANY amp! But your $3k will buy you some killer Double Impacts, far and away better speakers, and ones that can be beautifully driven with as little as 20 watts, something that sounds as sweet as the Raven Blackhawk. Which will never happen as long as you hamstring yourself with bookshelf speakers. Especially those bookshelf speakers. Seriously. Read the reviews. Replace yours with DIs, be amazed at how your whole system is transformed.
