“Some say the more money you throw at it, the better it will sound (especially when it comes to Aurender)”
That’s has not been my experience regardless of brand and Aurender is no exception. I have come to an understanding that the relationship between cost and sound quality isn’t always linear. There are numerous factors one must take into account such as system synergy, choice of downstream or upstream components, room acoustics, tweaks and personal listening preferences….they all play significant roles in the overall perceived improvement.
While higher-priced models often incorporate advanced tech and superior parts that can enhance performance, the actual degree of auditory benefits may vary given each listeners audio system and listening skills.
