Item: Green Mountain Audio Chroma HX speakers with stands Location: Singapore Price: $2500 SGD Item Condition: Excellent Reason for selling: Upgraded Payment Method: Pickup - Cash, Paynow Extra Info: Selling excellent sounding GMA Chroma HX speakers with Solid Steel stands. Condition is very good. The Chromas have some magic about them that draws you into the music. Maybe it’s the time coherence, or the inert cast marble cabinets or their stealthy, acoustically low reflective shape or a combination of all. I loath to let them go but I have to make space for the new speakers. I bought this directly from Roy Johnson (RIP) of GMA about 5 years ago. Cost me almost $5,000 SGD (just the speakers). Buyer to self collect from Woodlands. Can audition if there is intention to purchase. Interested parties can contact me at 9749 0078 Key Specs: 91 db, 4 ohms, 1st order XO, Cast marble cabinets.
