One Synergistic Research Atmosphere XL4 multi-wave RF field generator in a fantastic condition. Imagine listening to Charlie Parker at Birdland, then walk into Carnegie Hall and get seated in the best seats in the house. This is possible when you add Atmosphere to your listening room. No other technology allows you to tailor the size and scale of your soundstage, with stunning realism, to accurately portray the music and venue you are experiencing. Atmosphere is a two-channel, multi-wave RF field generator with the power to transport you to the live event. Simply place Atmosphere it your room, turn it on, and tune out. All original accessories are included (Red ATM Atmosphere Tuning Module, spikes, cables, manual). As an extra you will get a Green ATM Atmosphere Tuning Module also. Compared directly to the original Red ATM the Green ATM is a faster resonator portraying acoustics and recordings with a lower noise floor for enhanced detail and air. Notes seem to decay into a darker background while the overall sound field seems to extend further in all directions; front to back, side to side and top to bottom. The original box is included. Retail prices are 3.495 euro for the Atmosphere XL4 and 695 euro for the Green ATM. Please check our other items. Free shipping worldwide!
