Luxman 509 or McIntosh 8900

Probably too late to add but I lived with a Macintosh amp and preamp for many years, decided to finally upgrade and for various reasons went with the Luxman 590AXII and now wish I had replaced the Mac’s years ago. The Luxman is more detailed, warmer and much less fatiguing.

That's my experience too, but my time with Mc is so short I hesitate to say anything.  What speakers were you listening to with each though? 

I have never heard anyone who owns McIntosh say they were fatiguing sounding. If anything, they are warm sounding. 

Deadhead1000, were using direct coupled McIntosh amps?  As Stereo5 mentioned fatiguing would be the last thing I would categorize McIntosh ampa.  If anything warm and at times lacking crisp details would be my experience.  

I had the Macintosh MA6900 integrated amp several years ago and, based on my retailers advice and demo, I finally purchased the Luxman L-590ax II. The Luxman amp was more detailed, more musical, clearer, warmer and I enjoyed it very much.

My next upgrade was to the SimAudio 700i V2 integrated amplifier and it took my musical listening to another level. I auditioned the 700i V2 amp and liked what I heard using my PMC Twenty5.26 speakers. My new SimAudio 700i V2 amp sounds excellent with clearer sounds and more musical detail.

If possible, audition different amplifiers at slightly different price ranges to narrow down the range you can afford and sounds the best (to you). Take your time and listen. When posting on Audiogon, you are getting opinions from others and that is useful. However, I suggest you audition the McIntosh amp and the Luxman amps and decide based on what YOU hear.

As posted above, I agree the Luxman L-L-509X is a great sounding amplifier and, as I noted, suggest you audition it so you can make the correct decision. Please do NOT rush this process.
