"...will the tidal masters really sound much better?"
That is a loaded question! Can o’ worms, etc., etc. :-)
You should search the discussions by entering MQA. I’m kind of cynical about MQA. My issue is the source material. If applied to some well-recorded first gen analog master tape, I guess it could sound even more wonderfuller than the non-MQA version. But garbage in/garbage out still applies whether sprinkled with MQA fairy dust or not. I already hear as much if not more difference in the SQ of "conventional" recordings as what MQA seems to bring. Do I really need to spend for an MQA capability? Hope that makes sense. Yet another black mark against my audiophile credentials, no doubt. I’m sure others will have a different view. Listen to ’em! BUT, bottom line: trying and listening is the only way you can know if it’s "better" to/for you (your ears, your gear). The Red is a pretty low cost way to get the experience. You can probably even get one from a seller with a return policy. Good luck.
