Omar Zulfi, music producer, musician, and owner of DeviantNoise.com, told ZDNET that first and foremost, you need to make sure that what you’re getting has all the modern-day connectivity you may require, like the most recent Bluetooth/wireless chips, a substantial variety of inputs for HDMI, USB, a phono input for plastic records, and RCA inputs for old cassette tapes. “It should also work with the most recent audio innovations– Dolby Atmos, Dolby Vision, etc,” he said.
Zulfi included that you intend to ensure the system you buy also has respectable adjustment controls (bass/treble/sub degree, and EQ setups) so you can customize your system to your space.
And, as far as tech specs are worried, pay attention to the regularity action.
“A vast regularity reaction (as close to 20 Hz – 20, 000 kHz as possible) and a high Signal-to-Noise ratio (SNR) are two specifications that customers can look for,” Zulfi stated. “Frequency response determines exactly how well and plainly a noise can be reproduced by the speakers, and SNR effects the background sound when being utilized (i.e. low level hiss/static).”
