I just ordered a Cary Audio SLP-05... - Page 3

Thread Starter 
Well, trying to figure out what the issue with the Cary's headphone out, I made some measurements, and itt's very interesting. The headphone out seems to high-pass filter it's output below 100 HZ, with what seems like a 12db per octave filter. So while 100 HZ output is fairly strong, by 50 Hz the output is greatly reduced.

Now what I am trying to figure out is WHY they did this. I have to assume it was intentional, so maybe they were covering up for some weakness? Very odd, and very unfortunate. I think it could be an outstanding headphone amp if they didn;t do this - the sound above the bass is excellent. But you can't remove the bass without making the music sound thin, as Mark and I have both found.

I also measured the preamp's output, and of course, there is no such roll-off - there is very strong bass, with VERY strong output at 25 Hz, and fairly strong output at 20Hz.

So while I am in love with it as a pre-amp, and it's staying in my system, I've moved the Decware CSP-2 into my main hi-fi to serve as my headphone amp. I had been using the Darkvoive 337, but there is no room for it along with the Cary - the CSP-2 fits because of it's narrow-but-deep design.

You might want to give Cary a call and talk with them and maybe they can make a change to this for not too large of a charge. If it is that good above the bass, Cary might be able to resolve the issue. I am sure it was all a trade off as someone typically buying the unit isn't buying it for its headphone output.

Thanks, Steve - that's a good idea. Now that I really know what's going on, I am going to do that.

The idea of contacting Cary is a very good one, hope they can resolve the issue and make the headphone out as good as the pre-amp. Good luck.

That sounds like a great Idea, I bet you can get a hold of Dennis pretty easily!

I think they went to enough trouble to add a separate headphone section, that would like to know that it is useless to someone fussy enough to want a $7000.00 pre-amp.

For the price of the Cary, the whole thing should be excellent, and it lacks as a headphone amp miserably.
I would compare it to a B52 as a preamp, and if its that close, id get that so i would have an excellent preamp and also headphone amp as well.

I agree in the main. The Cary is so good as a preamp I am keeping it, but its headphone amp is not good enough to be usable, due to the very obviously rolled off bass. That is a shame.

The B52, IIRC, does not have a phase splitter to send a unbalanced input to the balanced preamp outputs, and as such, was not a good choice for me (someone please correct me if I am wrong on that).

Anyway, I love the Cary, and it's here to stay. For what I paid (since I got it used), it's well worth it for me, and I have plenty of headphone amps
