Advent Loudspeaker based stereo system

FWIW, I've got a Kenwood KA-5500 powering my stacked Advents right now and I really enjoy the sound. With just a single pair of Advents, I've used my Fisher X-100-2 little integrated tube amp which is about 20 wpc and it sounds fantastic in my living room (19x14x8). The former is my summer setup and the latter used in the cooler months.
Love the look and the meters on the Kenwood.
 
I was gifted it a few days ago and am really impressed with it, I have several others from the same time period with similar specs but it has an interesting sound. I ran two simultaneously going back and forth and its got something I like.
 
There's a Marantz 2216 not too far from me, but man I don't know that 16 watts per channel would get the job done. I am pretty happy with the sound I'm getting right now in my garage with the 90's Kenwood setup. I would like a cool setup in my house but I'm not going to rush it, I'll just keep my eye's open for a high-quality piece.
If you already had the Marantz 2216, that's one thing... but looking for one on the market I'd go with more power. Yes, don't rush it.
 
I think that LR-9090 was made by Planet Research. About $550. Stereo Review came to the conclusion it was a 108 watt @ 8 ohm receiver when they tested it. They liked it.

The LR-9090's a very nice receiver , 350.00 sounds about right I gave 225.00 for mine more than a couple years ago . The power switch usually poops out on these receivers , theirs a fix for that problem search for K7sparky's thread.

Lafayette commissioned Setton for the LR-9090 its a Setton RS 660 their LR-5555 is a Setton RS 440 and the LR-3030 is a Setton 220

Setton didn't make any of the Setton receivers. The Setton RS 660 and all the Settons were a Planet Research job like the Lafayette LR-9090.
 
In my opinion, if you want to have them sound like Advents, just restore them to original condition and forget about all the other supposed "improvements" like cabinet bracing and different stuffing and super expensive "audiophile" capacitors. Some people just can't resist messing with a good thing. You may end up with speakers not as good as the originals.

Those most likely have the 16uF, 16uF combination so just get those and be sure you compensate for any ESR difference between the originals and the new caps.

Hey Doug,
I love the idea of keeping them as intended since I do want them to sound as good as possible. I'm as wet behind the ears as can be on this subject when it comes to replacing caps etc. I don't know what I don't know... With that being said what resources could you point out to me to keep them stock and get them back into shape? Thanks
 
First, after reading my post again, it seems I am calling you one of the ones who can't leave well enough alone when I'm not. I am referring to many threads I have read about "improving" Advents without considering Henry Kloss' intent.

Anyway, if the resistors and inductors are OK in your speakers, just leave them alone. If you want to replace the capacitors, the originals are non-polar electrolytics and that's what I would use to replace them although it probably doesn't make a whole lot of difference if you want to use film caps.

Rick Cobb's surrounds are great and that's what I used on all mine. They are like the originals, very compliant (floppy) and the roll width is 17 - 18 mm. The roll should pretty much fill the entire space between the Masonite edge and cone edge. Other suppliers have seen the light and are now supplying the same kind when, a few years ago, many were selling ones that were way wrong with small rolls and stiff foam.

Capacitance value is only one of two variables that are likely to change over time for electrolytic caps such as those caps in your pic. The other variable is equivalent series resistance (ESR). Generally, ESR increases over time, making the speaker sound like it is muffled by a heavy blanket when it gets really bad. ESR is also hard to measure at audio frequencies unless special equipment is used. Most inexpensive ESR meters measure at a frequency well above the audio range, and since ESR varies with frequency, measuring above the audio range is useless.

I bet you would really like the Der EE de-5000 lcr meter. It has the ability to test at 120hz, which the capacitor manufacturers recommend. 100hz 1khz 10khz 100khz also.
Goes to 20,000uf too.
 
I'd like to do as good of a job as I can for as cheap as I can, but I want it done right or there's no point doing it. Doug, I didn't read your post as derogatory, just somewhat cynical and I believe rightfully so. I'm a bit nervous about investing money in things I don't fully understand with no idea of what the end result will be. I don't own a multimeter, but I can borrow one from a family member. I ordered Cobb's kit, so I'll be sending the one back from Amazon.
I'm still on the fence a bit about the receiver... I'm scared to spend a few hundred bucks on a radio and then end up with something equal or less than what I already have. Even though it may be really cool to look at. I plan on putting these speakers on my desk, with either an amp or receiver powering them to stream music in my living room. I want to be very real in my expectations and what I will be using them for, 90% of the time they will be ran at levels not much above speaking level because I'm sitting 4 feet in front of them.
The other 10% will be when I am 20 feet away in the kitchen/ dining room and will play them a little louder.
I have several AVR's and other power sources in my garage, but I'd really like something nice and close to period with good high quality. somewhere between $100-$200 is my comfort range. I don't care much for radio, so a tuner doesn't do much. I do really like the look, but I could really make do with an integrated amp.
 
What a spread!? So I find a couple Pioneer SX 626's, not ideal but cool looking. One guy wants 125, the other $430.. Um. Wheew. So far I have a Kenwood KA 501 Amp or the Lafayette for double the cost. This is a kind of nerve-wracking endeavor and I can see how it becomes habit-forming.
 
But, I love bass. So, you may be right. I just want to make sure I don't blow my wad on a unit that won't get me where I want to go.
 
If you want your power from something close to the vintage of the Advents and want to keep it under $200 you may need to be patient. For a variety of reasons the asking price for many, maybe most, vintage receivers is well beyond sanity IMHO but if you wait long enough something will show up. As far as integrated units go, I don't remember anyone trying to sell me anything but receivers back then so they might be scarce. Perhaps subscribe to AK and see if you can find something in Barter Town. Power them with something else in the mean time.

Not to make this more confusing for you but here's another idea . That Pioneer SX 626 has pre out , main in jacks as did many receivers from that time period (which would be right in the same time frame as Large Advents) use the 626 as a pre-amp into the amplifier of your choice.
You could get the vintage look and sound with more than enough grunt to make your Advents sing for smaller money , I agree with Goido57 the price for vintage receivers (especially so called monster receivers) has gone way beyond sane these days.
