post #5671 of 9514

Never thought I'd use the extra long cable that came with the Q701s, but I found a use!

Thanks for the reply, Lostream and Kramer.

 

 

I just heard the K702's this morning and I didn't like them.

The sound was too bright for me.

I imagine these would sound great with natural instruments but with aggressive guitar rock I found it too harsh and brittle.

I should add that they attached it to some cheap desk amp that could fit in ones pocket.

 

Is it unanimous here that the Q701's ARE different?

I tried to imagine the 702's with more bass (like the Q's) but the upper register was just too sharp.

 

For the first time in my life I'm leaning towards Senny's over AKG's.

Someone...please snap me out of this! :)

Yeah brittle  I think could be a good word to describe how the K701/2 upper mids differ from the K240s.  I get that sensation with my Millet hybrid every once in a while on certain tracks.  The millet is a unique circuit in that you can use a small pot to adjust the plate bias voltage to increase / decrease even order harmonic distortion.  Even with the plate voltages very low and distortion at its theoretical highest, it still does not mask-out the K701 upper midrange resonances that are much less problematic with my other tube amps.  Even my larocco PPA, a clean sounding solid state circuit does not trigger those upper mids the way my Millet tends to do.  Its no fault of the Millet, I think the amps builder used HD580/650 to tune it.

 

IMHO the K240s has one of the smoothest midranges I have yet heard... forward and energetic without being harsh.  I think the Senn house sound could be a nice alternative for you.

 

Yes I could readily hear the difference in bass impact/extension between my K701 and the Q model when I demo'd it.. and that was in a noisy HF meet environment and non-critical listening.

 

Like I said earlier 701 mids are strange with the wrong amp.  I think you just found this out first hand.

So is it safe to say that if I don't like the K702's... I won't like the Q701's?

nope... I think they are different enough that there's a strong possibility you could like one but not the other.

 

Keep in mind too that if you jump ship to Senn you are going to need an amp capable of driving 300 ohm impedence loads... to even begin to recoup the benefits.  None of these cans sound very good with the wrong amp circuit... IMHO of course.  The 55 ohm K240s is fairly easily driven too and more closely matches the impedance of the 701/2.

 

Here's how mister dummy hears the difference.

Great sequence.  That first picture is fascinating, esp. the two "water" jugs and the turntable(?) on stone risers...?

The water jugs are catch containers for my tea desk (so the desk doesn't overflow and water doesn't go everywhere) and the stone risers is my home rigged solution to isolate the turntable from vibrations.

 

Also, I felt silly just setting my turntable on the ground.

Not sure if this will help, but with the bass port mod (foam-covered, not fully open) and wool felt discs over the drivers (or something a bit thicker than the stock foam; just under the dust shield on the pads) my Q701s are much better suited for rock now.  Before those two mods, any ringing guitar solo was killing me.  If the source requires a more open sound, it takes less than a minute to switch the "driver" discs to something else (stock, some other foam, whatever; I've got 5 or 6 available just from experimenting).

 

I should add that I had the HD 650s for a while, driving them with my Lyr, and I prefer my modded Q701s by a long way.  Sold the Senns.

 

HTH.

that looks like jugs of head-fi cool aid, and the little Stonehenge scene from Spinal Tap.

I like the stone risers.  Tea desk... gonna have to google that one.

The best kind of Kool-Aid ;)

 

LMAO.  Maybe terance can post a vid of the dwarves dancing around.

It is a mix of yerba mate silt and pu-er tea rinse water.

 

I can imagine that it tastes absolutely awful, but perhaps I can sell it as a hi-fi elixer that makes people's audio gear sound better?

 

Hmm. . . what do I call it?

 

Also, I haven't seen spinal tap in forever, but that scene is great.

Just when I think I'm out...they pull me back in! :)

 

Yes, this does help, Thurston.

 

Is there a replacement cord that can be used to tame the highs if I find them too brittle on the Q's?

LOL :-)

 

I had Redco (in the US) make a short cable using Mogami mini-quad.  I found that the stock cable was slightly smoother/less brittle, but it was so slight that I might have imagined it.  In short, it's unlikely a cable will make that big a difference, certainly when compared to the mods or even a DAC.

$130 dollars later, my like-new Q 701 from Amazon are here! They are, in fact, the Austrian model and appear to have never even been opened!
