Tube headphone amplifier + amplifier or integrated amplifier?

I posted this in a recent thread .... but here we go again.


Sound Quest SQ-84 ..... if all you really need is 10 watts this amp will supply them. The amp doubles as a headamp and is impressively quiet even with higher sensitivity headphones like my senn 595's. The sound is punchy, clean and clear and quite musical. This amp is an excellent value and if you use new production tubes the tube cost is very reasonable. I am using the JJ Tesla 6v6s for the outputs and this is one of the best sounding new production tubes I have tried; $46 for a matched quad. The nos 6u8's used for the input and driver stages are inexpensive at around $5 per tube.

Get vintage gear for your integrated amplifier. Much cheaper than what you can swing nowadays, and yet still sounds good! Avoid Marantz/McIntosh for your first purchase, they command prices that are above what they are worth on eBay and elsewhere. Check out Pioneer, Kenwood and Yamaha pieces from the '60's and '70's for the best value-for-money - a nice little 20 - 30 WPC receiver/integrated amplifier ought to do for you. Scour local listings, online classifieds etc for gear for sale. Not sure where to do that in the UK.

Then buy a separate headphone amplifier, like a Headfive or the like, for your headphones. It'll work out much better than using an all-in-one solution.

Here's a dumb question about vintage recievers:

Can you play a modern CD/DVD player through these vintage recievers with good results?

If so, does it matter which input selection?

I've run modern CD players through a 25 year old Fisher reciever and they sounded fine. If the speakers weren't also 25 years old it would haave sounded better.

Use "Aux" or "Tape" inputs and they're fine. Phono inputs won't work. Put your turntable there. If you don't have one... well... you have a place to plug one in.

Very cool! Thanks. I must get one of these vintage recievers! I love the look of these, plus they only cost like a couple hundred dollars.

Yep, modern sources work fine. I have my Aux hooked up to my iPod, and I'm planning to hook up Tape A to the incoming Oppo universal player.

Get those speakers re-foamed and the crossover caps replaced if they haven't been - what brand/model were they, by the way? I have a pair of speakers that are twice my age (I'm 18, the speakers are AT LEAST 35 years old) and sound incredible. Two pairs, actually. A pair of Dynaco A25's as listed in my sig, and a pair of Smaller Advents that I use as HT speakers. The Advents have been re-foamed, and now they'll be good for another 20 - 30 years! The Dynaco's don't need re-foaming, of course, thanks to their rubber surrounds on the woofers and tweeters.

If you're paying a couple of hundred dollars... you're paying QUITE a lot for vintage gear. Of course, it depends on power, condition and features... Which receiver are you talking about? I have a Kenwood receiver that is in mint condition, puts out 60WPC reliably and cleanly, sounding almost tube-like; it only cost me ~100USD. With an small external omni-directional antenna placed directly on top - I didn't want to bother with a bigger, roof-mount antenna - it draws in FM like nobody's business, and the AM reception is incredible.

This is what it looks like with the lights on.



It also looks incredible when the lights are turned off. Here are some glam shots I had a friend take with a 20D.






Thanks.

Consider the cayin HA-1. It's a small headphone amp and speaker amp. It sells for 180 pound at ornec (http://ornec.com/product/GB/Cayin_HA-1A/), although i'm not entirely sure whether i'd buy off them.. they give off bad vibes to me, but maybe they're good

its fairly low power though, which may be a problem if you dont have efficient speakers or sit close to your speakers. with my ~99db speakers it was fine, but if your speakers have poor efficiency then u'd likely have trouble

Roastpuff,

To answer your questions on what brands of receivers I was looking at:


Various brands from this vintage gear website.

BTW, I love those pics of your Kenwood. Fabulous, especially with those lights. I too use an old Kenwood integrated which was handed down from my parents, the KA-95 model which I think has 125 watts per channel and it's from the 80's. I don't know if it would be as good as the ones from the 70's but it's pretty powerful. I can't get the volume past 10 o'clock.

That said, I would like to get a 70's receiver though since I'm a 70's freak. Perhaps the Marantz 2325, which is considered to be one of the great legends of vintage amps. But I doubt I would buy it unless I somehow find a great deal on it.

The Quad Lite has a crossover, so the impedance curve will be all over the place, and not friendly for SET amps or current-output amps. I'm afraid you'd have to use a "standard" solid state amp. Although you can probably use a SET amp if you're willing to sacrifice a bit of output. Usually amps like SET and Pass Labs are used for fullrange speaker systems, which include headphones.

If you get a fullrange speaker system, then you'd be good to go. They tend to be really efficient and easy to drive.

The Jasmine Serenade is a tube headphone amp that can drive speakers. http://www.jasmineaudio.net/serenade.html#
