    I AIRBNB'd a house in Petaluma, CA in the fall of last year and the owner had a Harman Kardon PM645vxi integrated amp that sounded great with some nondescript speakers. (I seriously looked for a label on the speakers and could not find one) Being a guy in my early 50's with fond memories of my Technics amp and a pair JBL 4311B monitors in the mid 80's, I became obsessed with finding this amp on ebay and rekindling my love of HIFI. I had become like the rest of the world and invested in a Denon AVR and Infinity TSS-750 home theater system. I was very excited to find the 150 wpc PM665vxi instead for a couple hundred bucks!! Thanks to you fine folks on AudioKarma I was able to take the unit apart and properly clean it. To stay on the value side, a bought a pair of Elac Debut 2.0 B6.2 on Amazon when they were on sale for $149. I am blown by this combo! The clean, clear, warm sound is amazing! Is anyone else still enjoying this integrated amplifier? I mean $350 for such a great sound! Let me know if there is another set of speakers that matches well with this HK. My Wife is not happy as I dont want to leave the man cave! No advise needed for that predicament. Haha!

    I have a PM645 non-vxi and a pair of PM665’s all of of which are excellent sounding amplifiers. Mine are usually paired with Klipsch Heresys or Chorus - great combos! Enjoy yours.

    Wow! 100+ wpc sounds like overkill for horn-based Klipsches

    I have a pair of PM665s, the earlier, not-vxi versions. The one that works sounds good, but has not been cranked up yet. It takes a little while to warm up (and fully drive both channels) and I believe that is just the ageing caps in the protection circuit. They will be replaced when I do a recap.

    The many, tiny push buttons on the PM665 are a pain. Mine are scratchy, as is common for these apparently, and hard to reach for Deoxit. That is on the to-do list also.

    Ive read the vxi version is a little different, not as solid a build in exchange for more power. I don't know how much of my PM665 issues should be expected in a PM665vxi.

    Yes. To be honest with you, I was shocked when, after cleaning, I fired it up and it sounded so good. A sticker under the hood showed that is was serviced in 1998. I hope it hangs on!!! I am really enjoying it. I'll have to find a reputable tech in the Detroit area just in case. The boards and capacitors looked good during cleaning. The exterior and some of the buttons need some work.

    Yep. I had a 655vxi and it was dynamite. Ran pretty hot, but sounded great. 2nd the dirty push-button problem.

    It takes a little work and disassembly but you can get deoxit down into the switches. Don't forget the speaker selection switch, too, which is located at the back despite the knob being in the front.

    The only real issue I've had with my units is the power protection circuit failing. The fix is fairly simple once you figure out which caps failed. I have an old thread on this in AK somewhere. A search should find it.

    Harman Kardon needs it own section/catagory. All the posts on HK are all over the place. How do we get this done???

    I asked that exact question... 2 (?) years ago and got the answer "AK has found it is better to have multiple manufacturer questions answered in one forum, rather than manufacturer specific forums, so searches and manual scanning finds more results.

    Disappointing for me, but I can understand the why.

    Thats B.S. HK gets no respect. If it did it would be included here.
