An older Sony ES player that almost never gets used, a classic Onkyo T-9 tuner, Airport Express steaming lossless with optical cable, Acoustic Energy Aegis Evo 3 bi-wired with Audio Quest cable, and an older Carver TFM-15CB running speakers in other parts of the house from the Decco pre-outs. I would consider next steps for either changing amplifier (the decco), using the Decco as a preamp and buying a power amp, or getting different speakers if the Decco sounds like it could be made more musical with more effecient speakers. thanks.
