Integrated Amplifier with the Good Bass and Extended Highs

I’ll chime in, since it’s been touched on. I own Luxman’s L-590AX, and imagine it may be everything you’re looking for. Used, around $4000 in great shape. 30W in Class A. To me, it’s stunning. Still certainly not cheap, but I bet it’s tremendously similar to the Accuphase. The newest version is the L-590AXII, this is their top of the line SS integrated, MSRP is $10,000+/-.  Mine is the previous version, two years old. I'd bypass their A/B amps and move up to the Class A.

The Parasound Halo has good bass, (I own one) however the Yamaha integrateds, like the A-S1100 are capable of silly good bass extension.They have a leaner tonal balance, but their bass capabilities make me laugh out loud.

@helomech,

I have the A-S1000 and it sure is not lacking bass drive.  That A-S1100 is next on my radar.

Primare I32 has more than ample bass and amazing, sparkling highs with no underemphasis of mids/vocals. I think the list is about $3,000. A new I35 is coming out very soon. I was really impressed with the Aria until I heard the Primare.
