post #12751 of 13726

As long as the volume works correctly after a good DeoxIt blast, that would be the last thing I would worry about.

Guys,

 

Back a couple of weeks ago I mentioned I had found a Pioneer SX-1050 in pristine shape (walnut looks new) and was giving it to my local tech for a tune up (tuner alignment, deoxit, DC offset adjust, etc).  Got it back last night...............and as you all said and I suspected, it made a world of difference.  Worth the $95 he charges for the service. 

 

Liked it so much I hooked up my HE-6 (new to me) to the speaker taps via the HiFiMan box and proceeded to blow a driver...............:eek:

OK, I blasted the unit with good amount of deoxit gold which has little bit of cleaning action because I don't have the red one handy.  I worked switch few dozen times and waited 20 min for deoxit to settle down, then I left the unit on overnight. This morning I gave a quick listen, hum... I notic someone (stupid me) turned MIC mix. So I truned it to "Mix Off" and hit the start. Wow, not only no more noise, the sound is just warm, detailed, powerful and with good dynamic from the headphone out. The HP output beat my MA6900 flat out. I can tell the PHO rivals many today's good HP amps. I finally have smile on my face!

Uh Ohhh...  Sorry to hear that bud :( 

 

Have you got warranty for the HE-6? I thought those hifiman's could handle anything... Obviously not vintage power!  

post #12755 of 13726
Maybe your pioneer has too much current rush out
post #12756 of 13726
Sorry to hear that, man. FWIW I would use the HE-6 from the headphone out of a 1050. Should be plenty of power.

Wow, missed a few days and I have missed a lot; concepts, sony separates etc. Great stuff guys. That concept is probably on a lot of people short list. That was an incredible find. The sony setup just looks stunning!

 

Oregonian I'm really sorry to hear that about you he-6. As I've said many times before, the higher end pioneers have the most power headphone outs of all the gear I've had. Driving cans from the headphone out is almost like driving them from the speaker taps. Hifiman have been know to do free repairs with out of warranty he-6, so I hope they will do the same for you if yours are out our warranty.

Happy to hear it!

I'm glad you reached for the aspirin (deoxit) before the brain surgery for your little headache.:)

Impressions when you get the chance, and welcome to the vintage club!

For real. 

 

 

I did some more interesting test today. I was trying to find out if the noise is really gone, so plugged in my Shure SE846 IEM in!!:veryevil:

 

Silent!:beerchug: I put music on pause, and I increased the volume pot from normal listening level 10:30 (I like loud by the way) to 3:00 pm, nothing! Wow. But I did not try to max out because I have a 2-year-old son, I am afraid he is going to bump into me and my ears are done. The preamp's max volume is about 5:00pm

 

Those bass and treble adjustment are very handy for difference sources of music. As whole, the amp is warmer than neutral, and a hair thicker than neutral. The transparency and effortlessness is amazing. Dynamic is not as quick as other modern amp I heard such as Pass Lab 250. But for a vintage piece, the naturalness and musicality is remarkable. All these good qualities are just came out the PHO, too bad amps don't have nice HPO like this anymore now days. The bass is very muscular but not very fast, I don't have problem with music transition though. Orchestra has very good sense of scale and dynamic at louder level. Female vocal is very attractive and male vocal has correct tonal balanced. Sony got both right, not bad. The amp is nothing like people complain about vintage amps, overly warm, fat bass, dark sounding, etc. The amp has very good even balance across the frequencies with a hair airiness on the top, nicely touch-up the sound. The amp somehow outputs according to headphone load, as I was expecting  the volume will get loud very quick with sensitive IEM, I was wrong, the Shure just has about one o;clock more than my AKG K271s 55 Ohm load at about 10:00 o'clock. The UV meter show the output difference too. I had the AKG for about 12 years now, so I know the sound very well. I don't have other headphones to test as I sold them all LCD-2, HD650, and T1. The amp WILL adds more body to the sound, so LCDs are not recommend here. So far the price to performance ratio has blown out of the window for this amp.

 

Here is my question, all your vintage amps HPO are nice too? Which is the best one for HPO?

The headphone out on my Pioneer SX-1980 is so good that I no longer own a single dedicated headphone amp. Not one. I'm still reviewing them for InnerFidelity, and so there are usually one or two here, but they are review loaners. For my own use, I actually PREFER to use the SX-1980. You put it very well - there is a transparency and effortlessness that is hard to imagine.
post #12761 of 13726

Wait.............there are dedicated headphone amps available?  :eek:

post #12762 of 13726

This thread is going to jack up the price of vintage gears, you just watch. Start with Pioneer SX-1980. The trend is like 6SN7, 6F8G, and GEC 6AS7... Especially the GEC 6AS7 as I got them for $50 a pair years ago, I thought was very expensive.

Well, a lot of the vintage gear prices are already fairly high. It takes a lot of luck and patience to find and 1980 for less than $2k anymore. I really enjoy hunting for the deals though, and do love when I find them. And I think you're talking about tubes with those part numbers. I've got two distinct tube-based headaches running right now, but that's a frustrating set of stories better shared over a pint haha.

 

Good news on other fronts though: I've found a nice piece at a score price and am firing up the minivan to pick it up this weekend. Only known problem is that the *ahem* blue meters are wonky, and the wood case can use some TLC.

Also, as of Tuesday, my sx-1980 will finally be off for a complete restore by mattsd, a fellow recommended by Skylab.

post #12764 of 13726

You are right. the price for SX-1980 is already pretty ugly.

Just out of curiosity Skylab do you still use your Leben CS-300 or mostly the SX-1980 ?  I realize the Leben is not a "true" headphone amplifier but most Headfiers probably consider the Leben for headphone usage.
