Soulution 511 vs. Luxman m900

Both amps are excellent in their own merits and it’s all system dependent. Go listen to both amps in your own setup / system and decide which one would be a better match in your own setup/system.
It’s all about system synergy. There’s no such a thing as "one size fits all" in this hobby.

As suggested earlier by almarg due to extremely low input impedance on the Soulution 511 would make a preamp pairing a lot harder than the Luxman unless when paired with its matching Soulution preamp.
Something to be considered.

Yes the Luxman is pin 2- in its normal position, but it also has a setting for 2+.

@hiendmmoe Are you referring to the BAL LINE PHASE INV switch?

@almarg Would you mind expanding a little on your statement

In that situation an alternative approach to achieving correct overall polarity would be to use a pair of XLR cables between the preamp and power amp which have the connections to pins 2 and 3 interchanged at one end

I plan on getting the m900u and trying it with the USA made Benchmark LA4 preamp. I plan on using XLR cables from pre to amp. Your statement above is my scenario. How does one actually interchange the connections to pins 2 and 3?

@hiendmmoe Thanks for pointing that out. I hadn’t noticed the "bal line phase" switch on the rear panel of the Luxman, which it seems safe to assume will take care of the polarity issue I described.

@yyzsantabarbara Although that switch makes it unnecessary to have the connections to pins 2 and 3 interchanged, typically that would be accomplished by ordering cables from a cable supplier that would be custom made in that configuration. Or by sending existing cables to the supplier, for them to rewire at one end. In some cases DIY ("do it yourself") might also be feasible.

Hey Craig ... I am not sure why you have to resort to personal attacks. And since you asked, I like the T+A 3000 so much that I ordered the newer PA 3100 HV. It should arrive in a few weeks. Cheers!
