Integrated or Amp/Preamp combo for Magnepan 1.7

I had the same experience with the W4S STI-500. Did lots of things well but had glare or hardness in upper mids with my Usher Be-718's. I switched to NAD M3 which cured it but also lost some detail and space around instruments. The M3 did sound very powerful and substantial and I would've kept it except I couldn't see the smallish display from my chair. Now using BAT VK300xSE with AZ Adagios so I have the tube pre/SS power combo like you mention above. Works great and I can't wait to listen after work every day.

Some suggestions after having been through a year of breaking in my 1.7's

1) start with interconnects and power cables... they can contribute to glare which is commonly what people are reacting to when they say bright. I use the PS Audio jewel power cables, they do help improve bass and clean up grunge. Interconnects are harder to pigeon hole as source-pre electronics interaction varies. Try some place like Wireworld that will let you try before you buy.
2) turn your speakers backwards... the vertical magnet strips on the front panel side create a Fresnel lens like effect that reduces off axis imaging.
3) you don't mention your source, so that makes me wonder if the source is possibly the origin of some brightness.
4) maggies take about 60 days to break in... during which time they aren't yet at their best bass or transparency because like new shoes they don't have enough wear to be fully supple.

I suspect that you may be disappointed if you don't sort through these first... the problem may still be there after buying new amplification.

Very happy with Prima Luna Prologue Premium integrated vs
my prior solid state amplification... but that was more of an oil color vs water color tonal color change ..improved vividness, not a change in tonal balance. If better tone color does matter to you, $3K gets you their Dialogue Integrated which is even better in the bass..

Thank you both for your response(s). Davide256 - Source is either a Clearaudio Concept with Jolida Phono Pre or MacMini with Eastern Electric DAC. I notice glare/brightness using both. I've tried swapping the maggies, but not turning them backwards. I will look into both of your suggestions. I'm considering an Odyssey for the SS amp, but not sure that is the way to go.

Sounds like you are worried about wattage... don't be. In your price range consider the Rogue or the Prima Luna integrateds. Tube amps rarely irritate like solid state amps can and can help tame irritations from other components. I don't miss the greater wattage my Musical Concepts modded Hafler had... I hear more interesting things with tube amplification.

I am a Magnepan and Hegel dealer. We have recently set-up over ten systems pairing the 1.7's with the Hegel H70 or H100 integrated amps. At $3k, the H100 would be at your price point. It is quite a step above the H70. It will not clip, even driven wide open, due to its "Sound Engine" technology. Just thought I'd chime in and let you know what I believe to be a great combo at a nice price point.
