Amps that can drive the HiFiMan HE-6 planar headphones - Page 161

post #2401 of 3521
It's been a while since a listened to a current model, but from everything I've read over at audiokarma, a fully restored/recapped 2205 is on par with their current amps. I don't know if it's the type of caps I used or not(all nichicon muse) but I would discribe the sound as only slightly warm. The gsx mkii for example would be warm compared to my 2205. But if they did keep the same sonic sig throughout the years, then we definitely agree with the bass qualities. But the slight warmth and boosted(but still tight) bass from the 2205 do make them sound fun.biggrin.gif

You are a lucky man.

 

How much power are you commanding the HE-6 per channel with that 2205, watts wise.

Well it's rated at 200wpc. But mcintosh is very conservative about their specs. I've read reports of this beast producing anywhere from 240 to 280wpc on the bench. But with the power guard feature engaged, it will be capped at 200wpc. So I would guess around 40wpc give or take for the he-6 which is way overkill(but sounds so good).

 

So at that wattage, I purchased a couple of resistors to protect both the he-6 and the transformers(yeah I know it's a solid state amp, but the macs actually use a pair of output transformers just like transformer coupled tube amps do). But the strange thing is, I don't know whether it's the auto transformers or the equally impressive mac preamp, but I use the same range on the knob with or without the resistors in place.

How do you have the resistors configured? If they are in parallel across the speaker taps then what you say makes sense. They provide no attenuation when just across the speaker taps.

anyone tried the HDVD 800 or HDVA 600 with an HE-6 before?

post #2406 of 3521
Yes and it not suitable at all. Do not listen to anyone who says it is

post #2407 of 3521

too bad, why do you think that? Is it mainly because of the slightly higher output impedance which could alter the sound or does the amp simply have not enough power?

post #2408 of 3521
Not enough power. It plays loud but not with correct balance of sound. Bass is very light and mids too. It's basically tinny. This is why pepole go crazy with the he 6. It's not how loud it's the proper nance of the sound.

I kind of thought that in the beginning. But people over in the regular he-6 thread was saying that it lowered the output when used that way. I didn't want to question it since some were more knowledgable than I. So thanks, that's good to know it doesn't lower the wattage.

Try this. It is what some have done and me as well.
Resisters needed two ten ohm 10 watt and two 2 ohm ten watt
Take the 10 and 2 ohm put in series acros the output terminals
Put the he6 across the 2 ohm resister. It will give you attenuation
It will give you about 8 ohms across the speaker terminals
It Lowe the noise floor of the amp.
It also alows the volume control to move up to 11 o'clock or more.
It is important to have the volume control near the middle
For best sound.

I did get a chance to try that pairing and I found it to be surprisingly good. Not optimal, but it was enough to make the HE-6 still sound better than a perfectly driven the HE-500.

I seriously doubt that
post #2413 of 3521

anything under "perfectly well driven" wouldn't do it justice anyways ;)

I am not sure you can doubt an opinion. . .

 

Impressions were asked for, I gave mine which I stand by.

According to Rob's calculator it doesn't give a speaker load of 8 ohms:
