She sure looks the part, that's for sure. What a beauty! Congrats.

Well, I haven't gotten to listen to the SX-737 much yet, but it is a fantastic companion to my HD700.  For rock and such, the loudness switch turns on fun mode quite well, and while I haven't given a classical a try yet, I have absolutely no worries about it's capabilities.  Part of it could be the dac I just got in as well, but as a combination, I am loving it.  I do not have any feeling of I wish there was more bass with alt rock, and there is certainly bass to spare if I start turning that shiny silver knob.  I was worried I'd listen to it and have buyers remorse, but all doubts are gone, which for such an immediate response, I'm happy I don't have to take some time to see if it grows on me.

Good for you Saoshyant.  There's not much worse than "buyer's remorse" when you spend your hard earned cash.  The best part is as you stated, you won't have to time to see if it grows on you.  The chances are usually good of that happening with Vintage Amps; it's been my experience so far anyways.  Congrats again. :beerchug:

Your new 737 is gorgeous!

Y'all are inspiring me to dig out some of my integrated amps and receivers and take them for a drive with my headphones......

I feel the itch growing.....

Must get more headphones. cool.gif

Maybe a vintage pair of Koss Pro 4AA.....? biggrin.gif

Congrats! Now let's see if you can stop at just one. Vintage gear are kind of like Doritos. . .

Hey, I am wondering if you guys could help me with out with a couple of short questions:

 

1. I've read that replacing all electrolytic capacitors is absolutely essential on any vintage amp. What are the effects of doing so to the sound? And, what are the risks of not replacing them?

 

2. Do I have to replace the power supply of my vintage amp simply as a matter of age?

 

3. If anyone here is familiar with vintage NAD amplifiers, are you only supposed to bring the volume knob to 12 o'clock? After which it begins to distort? Or, is that actually a problem with the age of the amp rather than the inherent design?

 

Thank you guys so much! I don't even want to listen to my vintage amp because I feel like it will explode if I don't get some repairs done :(.

--- I have found that replacing all the electrolytics seems to improve the the punch of the amp.  More clarity/detail too.  In the case where you don't replace there is always the risk that one of them will "blow lunch" and take some other component with it.  So if you can afford to replace it is a good idea.

 

2. Do I have to replace the power supply of my vintage amp simply as a matter of age?

 

--- If you replace the electrolytics in the PS that should be good enough (assuming there are not other issues).  The electrolytic caps in the PS are actually the first thing I replace because they are usually the first ones to go due to heat.

 

3. If anyone here is familiar with vintage NAD amplifiers, are you only supposed to bring the volume knob to 12 o'clock? After which it begins to distort? Or, is that actually a problem with the age of the amp rather than the inherent design?

 

--- Calling LugBug!!!

Good luck!

If the vintage equipment has been sitting unused for a long time, it is very important that you use a variac to bring the voltage up slowly and reform the caps. Saves a potential big mess.....

 

As long as the caps are good, you may not have to replace them immediately (I know that many will disagree with this). If you do choose to replace them now, you probably will never have to again.

 

Thank you. :D

Just replied to your pm bud.

 

But I'll just reiterate it here for others. NAD's are renowned for their very low distortion levels and thats one of the reasons they work well with the sensitive HD800. No other vintage amp I've tried has had such a black backround. 

 

Most (if not all) vintage integrated amps are NOT fundamentally designed for hp use. A simple resistor is in place from the main power supply to the hp out. So turning the volume nob up past 12 oclock will no doubt be putting extreme pressure on the small drivers. The HD800 have very tough dynamic drivers but are not meant to be fed that much juice. The distortion may very well be clipping. I can't get my 3020 passed 10 oclock without it being far too loud. 

 

Or... because you have an original NAD 3020 (1979) it may very well be the caps. If you are worried then yes send it in for an MOT, because they are great amplifiers and worth it imo :)

Excellent. Pleased you're enjoying it. She's a beauty too! :beerchug:

Thanks for the help. I think there might be a problem with some of the electricals, then. Maybe you could tell me which ones you think? 

 

By 12 o'clock (which is what I keep it at constantly when listening to good recordings), it is mostly loud enough for pretty decent levels of listening, but it's not extremely loud or anything (it's like a medium-high or lower-high volume level). Depending on the recording, 12 o'clock is sometimes fairly quiet, too... Only highly compressed modern music is very loud at 12, but even most modern music isn't close to blaring at 12. 

 

On my JVC vintage amp, I get it to 8 o'clock so and then start dying from it being excessively loud. That, I understand, would be because of the extreme levels of power that come from a speaker amp. Consequently, I think my NAD 3020 is not pumping out as much power as it should be (at least to the headphone out). Also, I heard this NAD 3020 on a pair of speakers and it was certainly loud enough, and I am pretty sure it was less than 12.

 

I think I would need a restoration on this ... Any suggestions on which parts should I check? The "power supply"? Perhaps it's just the headphone out that is not receiving enough power?

 

Any thoughts would be great. My JVC sounds better, right now, just because I can get it to a higher volume... It seems like on my NAD, I would need to get to 1 o'clock to get the volume level I want, except once you pass 12 o'clock, it immediately begins to distort.

If everything works as it's supposed to, there's nothing "essential" that you should do. There are subjective gains to be made by replacing certain items but you have to weigh the cost for that with the cost of the item. It wouldn't make much sense to replace too many things in a lower line receiver unless you planned to keep it a long time and not expect to get out of it anywhere close to what you had in it when it came time to sell.

If the speakers seem to sound OK and are loud enough for you - I am wondering if your phones are too inefficient for the NAD HP out.
