Luxman L-509X

Eric, agreed that the 509x and int 250 are both superb sounding amps and both should be listened to before making a decision. I had the opportunity to audition both the int 60 and 509x and one sounds as good as the other. My ears just prefer the int's smoothness and sweetness...I like the chocolate ice cream.

If you have $10K and are considering a Luxman, I cannot buy used on this one since I went and demoed them (will buy new) but for someone open to a used purchase.

In my opinion the difference with the m900u and c900u combo is massive compared to the 509x integrated. Yes, I have heard all three in the same room with the same gear (that is why I will buy new).

Edit: The price is for each unit not for both.

I auditioned a 509x a little over a month ago. It sounded good, no doubt. Great integrated. But it just didn't grab me or excite like the int. Had nothing to do with the quality of it's sound or build. It was more to do with it's sonic personality. As I mentioned in my post, I like the chocolate ice cream. You obviously like the vanilla. Nothing wrong with that.

I've heard the 509 right after hearing the D'Agostino Momentum.

While not a Momentum, it was not too shabby. Not shabby at all.

That price on AudioMart is absurd.  Those sell used for around 8K each. I got the C900 for $7500 and it was about 6 months old.  I can get them brand new for 10,500 each from multiple dealers. Do your homework people.
