Always clean the pots and switches with contact cleaner as there will be a build-up of oxides if it hasn't been serviced in a long while, this can make a dramatic difference too as the signal travels through all pots and switches.

 

Just a note on 70's Marantz in general and IME- They look lovely :) But there are much better sounding amps for a lot less money. Don't get me wrong, they sound nice and will power the HD800's well and add body - but what you pay for a Marantz you could have A LOT better sound (and a higher end model) for your money with a 70's Pioneer, Sansui, Trio, Yamaha or my particular fave with the HD800 an early 80's NAD.

 

This is obviously just my two cents as some are very happy with the old Marantz sound :)  

 

Just a note on 120ohm, I would advise anyone who thinks the HD800 can sound a little dry or thin (and there are peeps out there! ;) to try a high impedance output and see if it pleases them. I think it can work great if you want a more bassy HD800. These days I tend to think it can be a little bit overkill as the sub bass isn't as tight as lower impedance amps... But its all give and take and what you lose you gain etc... The NAD amps I mentioned above have very low impedance value for vintage and they sound more 'right' to me. 

 

THIS...

Thanks! Actually, instead of the PM, would you happen to have any recommendations as to some of these models that pair the best?

 

You speak highly of the NAD amp, but I don't know much about them. Is there a particular model I should be looking out for?

Plenty of deep tight impactful bass, smooth but extended treble, full open midrange. Combine that with superb speed, detail and dynamics and I could wish for nothing more.  :D

 

So I don't think it's just an impedance issue.

 

No doubt you're right!  Output impedance is just one interesting part of the equation when amping hd800's -- one means of increasing bass response and perceived fullness (but also bass bloom) by a few plainly audible db's as it goes up.  I don't doubt that there are many excellent ss headamps out there that pair beautifully with hd800's.  Higher output impedance is just an easily identified factor that can change the balance and FR for those who find them a little too lean or treble heavy.  

 

Honestly, I was surprised when I found out the output impedance numbers on the Sennheiser amps.  I would love to hear an insider perspective on how they made their design decisions.  Granted, I prefer the sound of my modded crack to my "boosted" o2 with hd800's, but 40 ohms seems relatively unusual among modern ss gear.

I tried the IEC setting and found the result a bit "muddy". I switched back to low impedance mode and never looked back since .  I don't know if this experience can be extened to other amps.

 

Actually, your experience mirrors my own with the mainline.  I use the low impedance setting (nominally 16 ohms but effectively single digit per BH's recent clarification on the topic) 90% of the time with my hd800 because it sounds cleaner, tighter and faster to me, and the mainline has 0 issues with strident trebles.  

 

I don't mean to suggest that high output impedance is somehow objectively better when amping hd800's, but try the following: listen for an hour with something like the o2 and then jack them into an OTL amp or vintage receiver for a very refreshing change of pace.  At CanJam, I went from listening to hd800's on a headamp max to Woo Audio table.  They almost sounded like different headphones.  Kind of like that thread regarding the android app fiio is developing that makes one headphone sound like another purely through eq.

That's a point that characterizes very well the HD800. This can can really sound differently depending on the upstream gear associated with

I tried a HD650 last WE. it sounded beautifully on my Sonett/Octave Rig but the first and main thing I thought is that i don't need a HD650 as compliment. my HD800/Sonett/Metrum Octave system covers all bases for my personal tastes . I can really enjoy every music I want without any need of another headphone.

 

That been said, i'm really interested in listening more amps, dacs & headphones despite the fact I'm fully happy with my current rig. :beerchug:
