I do think Mcintosh and pass lab com out the different sound, they are so different, and someone prefer this one while others prefer that one. There is no right or wrong. I bought Mcintosh Amp brand new and used for about 7-8 years and go to Audio Research near 30 years ago. I have clear memory about the Mcintosh and maybe later, I will buy one as second system, THE MAIN POINT IS
I FIND RELEASE IN THE SOUND.
The following is coming from chatGPT and I agree.
Comparing the sound quality of amplifiers, such as those from McIntosh and Pass Labs, is subjective and can depend on personal preferences, the rest of your audio system, and the type of music you enjoy. Both McIntosh and Pass Labs are reputable manufacturers known for producing high-quality audio equipment, but they may have different sonic characteristics.
McIntosh is often recognized for its warm and lush sound signature, with a distinctive visual style and a long heritage in the audio industry. McIntosh amplifiers typically provide a smooth and musical listening experience.
Pass Labs, on the other hand, is known for its focus on transparency, accuracy, and detailed sound reproduction. Pass Labs amplifiers are often praised for their clean and precise audio delivery, making them appealing to audiophiles who prioritize accuracy.
Ultimately, the "better" sound is a matter of personal taste. Some people prefer the characteristic sound of McIntosh, while others may lean towards the precision and transparency of Pass Labs. It's recommended to audition both brands if possible, preferably with your own audio source and speakers, to determine which one aligns better with your preferences and complements the rest of your audio system.
