Do true audiophiles own Mcintosh gear

Vintage Mac gears were great.
They were the best looking amp back then as well.
Although they might not be the best sounding at that era but they're sure one of the reference amp in that era.
The Monos like MC30/MC60
The stereos like MC225/MC240/MC275
Many of the modern amps still don't sound as sweet as these vintage amps.
The vintage tube Tuners is still one of the best.
MR67/MR71 still sounds better than many of today's top tuner.
The preamp are decent as well. The C20/C22 were the best from that time.

So, it depends are who you are and what you listening to, the gears may vary as preference may vary.

Sounds the the original poster is chasing a name brand every audiophile will applause to. Sorry that Mac in audio is not the same Mac as Iphone or Ipod.
It is hard to define a "true audiophile" since everyone can have their own opinion about who should/shouldn't consider an audiophile.
If you really passion about something then price and name brand doesn't matter. This is where DIY comes into play.
If you go to the diyaudio forum then they wouldn't think any commercial product can be any good.
I also owned Mac and heard Jadis and used krell and ML and PASS. Sure I have tried hundreds of cables before as well ( some cost up to 5K.) In the end, it is not how much you spend or which brand is the best. It is what goes into your ear that matters. Is Mac gear make you a geek or an audiophile? ( you became audio fools if your ear is based on name brand ) No. It is how things sound to you and not the wallet. A true audiophile owns good sense of what sounds good and doesn't care about meter measurements.

Dave_b, Things does require a journey for your realization : )
Less might be more. That's why DHT SET amps had became a recent trend.

Happy listening.
