LUXMAN L509X VS M700/C700U

If you have the budget separates 900 series will outperform all previously mentioned.

The only amps I can say smokes everything I had owned are Mastersound PF100. Yes best ever up to date in my journey. 
Lifetime investment.

Best,

My Dac da 06 is arriving next week I can’t wait to see and hear with them 
word out there says that this Dac makes things less bright 

@rizwanalimohd There was a British review of the 509x integrated and it stated that the preamp and amp sections of the 509x were derived from the 700 series. If I can find that review I will post on this thread (later tonight if I find it)

I have demoed both the 509x and the 900 series on the same system and the differences were rather large in favor of the 900 series.

@mountainsong  What preamp or DAC with volume are you using the m900u amps with? I am thinking of going with the $2.5K Benchmark LA4 preamp instead of the $15K Luxman c900u preamp. I will do a 30 trial with the LA4 preamp first but I was curious if others used anything other than the c900u.

The Oppo is probably not doing a great job with that system as a preamp, a good preamp can make or break a system.

You should borrow a Luxman preamp and see if it makes the system way better. Other good options is a good tube preamp.
