15 to 20 VRMS if you want to turn it up...

Would I have to use the speaker adapter for the PMA 750 or could I do it through the HP out?

i had no time to research as theres a lot of post .

is it the same using speaker adapters / and using the hifiman HE adapter ?

Depends on what you mean by "the same".

yeah sorry I mean the Hifiman HE adapter..

 

PMA 750 here if someone else can chime in

Nope, most regular adapters don't have any resistors in them. The HE adapter does. There seem to be two pertinent questions: does your amp require resistors (which I'm guessing yours does not, as it outputs 160W into 8 ohms), and if so is the HE adapter the best choice? 

 

There are plenty of guys around here with exponentially more knowledge than myself, but I'd say you're fine running without resistors.

awesome thanks.

 

I've got the PMA 750 going out to some great speakers right now so I don't want to sacrifice their main output. Can't decide on the HE-6 vs. the HD800 and I'm trying to figure out if I can even use the HE-6

I know that feel on the amplifier sharing, bro. A couple of things: first, if you don't want to have to unplug and replug every time you switch from speakers to headphones, you can look into getting a speaker switcher like the one Bryston makes. (I'm keeping an eye out for one myself for the same reason). Also, while I only got to listen to the HD800 for a short period of time and liked it, I wouldn't even consider trading it for the HE-6. Music is much more present and full with the HE-6 ;) 

 

One more crazy thought: a few people have had good luck running the HD800 from speaker amps too. Naturally, you'd need to be that much more careful, and getting an adapter with resistors made would seem prudent at the very least, but it might be something to look into as well.

Favorite amp ever, it's got litte speaker buttons so I can turn them off super easy (although also sentimental value to be fair..). Why would I need to be careful about the bolded text? I've been running my headphones thus far out of the headphone out and no problems so far, have I been doing something wrong? :triportsad:

HP out is usually just some resistors for attenuation anyway. Depending on the type of resistors used, it may or may not affect sound quality. Running it straight out of the taps could have noise floor.

 

It doesn't hurt to try both and decide which one is cleaner and/or practical.

 

If you have to use resistors, they aren't that expensive anyway.

ohhgourami, where can I find a review of your recently-acquired Krell on HE-6? :)

Sorry, I wasn't clear: if you are going to power your headphones from the speaker taps, then you'd probably want to bring some resistors into the mix. Out of the headphone jack should be hunky-dory! :)

As a guy who lives vicariously through the ludicrously awesome amplifier purchases of others, I second this emotion! 

post #2894 of 3119

awesome thanks so much both of you for the explanation about resistors!

 

any way to gauge if it won't have the harsh high end or is that more art than science?

(meaning can the level of pairing be guessed at all or just if it can or cannot drive them)

You guys are right, I have not posted an official review.

 

I can definitely say this the most technically capable and best sound amp I've ever heard. This is also the most expensive amp (MSRP wise) I've ever heard too. This amp is rated at 300wpc @8ohms but has been measured to produce ~390wpc @8ohm by stereophile, but when plugged into straight into the taps with no resistors, the background is almost perfectly black. As some of you know, I'm extremely picky about hiss. Only when I have my windows and doors at 2am with no other audible equipment do I hear the absolute faintest hiss through my HE-6. The power regulation is extremely good! This was the first thing I noticed or actually didn't notice. :wink_face:

 

When the music comes on, I understand why Krell is famous for their extremely deep bass. Have you ever noticed that songs may sound still a bit bloated and boomy even with a headphone and setup so capable? Not with this Krell! This Krell shoves the bass straight down your chest! The control is simply amazing.

 

The soundstage isn't as wide on this 300cx compared to the 400xi, but it goes very deep. Actually, this amp makes anything I've heard seem 2D. Other very good amps still seem like very well layered images while this amp is real 3D space. You are inside the music, it is not just floating past!

 

Another new aspect I've continually notice is texture. Not all male vocals are smooth, some guys have grainy voices and this capture it very well.

 

Micro detail retrieval wise, this amp isn't much better, if at all, than the KAV-400xi. Alrainbow is right that the 400xi still has a lot of potential if paired with much better DACs.

 

I've read a lot of people calling Krells analytical and thin. I have no idea why they would ever say that. I don't think the amp is warm either; Krell has no house sound; it brings out the qualities of your source.

 

Overall, the best way to describe the FPB 300cx would be an amp with huge presence and dynamics. No one could call the HE-6 a headphone, it is a head-speaker!

 

 

Hopefully I'll get my ACSS/CAST interconnect and would bring more clarity.
