Home Theater Receiver Upgrade

My home theater needs a hands-on tune-up. I have a receiver driving surround-sound speakers, yet the audio no longer sounds as full or properly balanced. I’d like an experienced technician to visit, trace every speaker wire, verify polarity and channel routing, and determine whether the current receiver can be salvaged or should be replaced. If an upgrade makes sense, guide me toward the right model, handle the swap, and finish with a full calibration—levels, EQ, HDMI/ARC, the works—so the room once again delivers immersive, reliable sound.

Deliverables
• On-site inspection of all wiring and speaker placement
• Clear recommendation: keep the receiver or replace it (include at least two upgrade options)
• Professional installation of the chosen receiver and tidy cable management
• Final calibration and demonstration of clean, even surround playback

Include a brief note on your experience with surround-sound wiring and receiver installations, plus your earliest availability for an on-site visit.
