1) Can I use a Sony STR-DE335 to drive a pair of Polk Audio SDA 2 speakers?
2) Is the Sony STR-DE335 a common ground amp?
3) With my Denon PMA-920, the (-) negative Polk speaker connections were cabled to each other, would that be necessary with the Sony?
Thank you very much,

Hey everyone!!

I recently came into a pair of Polk SRS 3.1TL towers recently and I am starting the long process of refurbishing them. I've already done some work to these and am just now getting around to documenting it. I'll report previous progress in the next few posts as to not have one giant post.

I am new to Hi-Fi audio and am willing to drown in all the small details. With that said if anyone has any advice or if I'm doing something incorrectly please chime in. I've read through a bunch of build logs and threads on the forum for awhile and have learned a TON from you guys.

Let's get at it.

Here they are! As you can see 14 year old me 12 years ago was a little a**hole and replaced a blown SL3000 with a "custom" driver. Ughh. I'm sorry.

I tested each driver and found 1 bad MW6511 dimensional driver, 1 MW6503 and another bad SL3000. I was able to order replacement tweeters directly from Polk and I was able to find pairs of both mid drivers on eBay. From my understanding Midwest is still working on a 6503 replacement but not the 6511. My belief is that the 6511 is going to be more difficult to find as time goes on. It's probably not popular or used enough for Midwest to spend the money to produce it. Sad. Makes me nervous for the longevity of these speakers.

Here is one tower with the replacement tweeter. The upgraded model from Polk sounds great. I need to shim up the screw shroud because for some reason the shroud is recessed further than the lip of the component. I'd hate to over-tighten them and crack the face of the surround. Probably just going to glue washers to them like @verb recommended in a previous build log.

OK folks, time to pass this fantastic deal on a pair of SDA SRS 2 to the next Polkie. A local forum member sold these to me at a smokin' price so I will do the same. These sound superb, but cosmetically they need some work. I would rate them 5.5/10 but they have a lot of potential.

Here are the upgrades:
Crossovers are original.

Binding posts are upgraded.

IC cable is original and looks to be in good shape.

Drivers are Dynamatted and seals are Armacell foam.

Tweets are RDO's with original gaskets.

Larry's rings are on, but no tweeter brackets (not available at the time).

Most of the MW dust caps have indentations; no effect on sound.

Spikes are removed but will be included so you can use if/when you like.

Cabinets are not great like I said earlier. All caps are solid (jointed ~3" pieces) and a few of the joints on the tops have split in a couple places. The left top cap has some water staining. One of the bottoms was replaced. The left back has some surface marking of some sort.

A lot of money is invested in these speakers.

$400 local pick-up or I can meet an established member in the area.

I will post some pictures soon...

Also attached via PDF is the user manual.

This has been a super reliable amp. Very clean, near mint except for the big blue light on the front in the middle seems a little dim on the left side.

For the money, good luck finding a better "watt per dollar" power amp.

$140 shipped via FedEx or UPS and I will eat the PayPal fees.

Hi Guys,

I am looking for a replacement tweeter for a used pair of RTI A3's I found on CL. Rather than throwing them out, I want to try fixing them.

Any idea where I can get them from other than the $90 options on eBay?

Cheers,

Jonathan

I turned my amps on this morning so that they would be warmed up for music tonight. Earlier I was cleaning, and tried dusting the stereo power cords where they enter the wall socket. I accidentally bumped the right cord, got a spark, and the right amp went off. Nor would it power on. Oh man, please don't be broke, I was thinking. I unplugged the amp from the top of the socket, and moved the plug to the bottom part of the socket. This is a dedicated line with only this one socket. Anyway, now the amp turned on. Whew! Not sure what happened, but as long as it works I am happy. Now I can't wait for music and beer starting at 6 PM.

Hi all,

New Vintage Speaker Day. I picked up a set of 5A's through the local FB Buy, Swap and sell.
They were listed as 5 Jr's, but when I picked them up, they were 5A's. Score.
Cost me $150, which is great in Australia, as these are thin on the ground over here.
This set has the Peerless tweeters, and black basket passive radiators. Markings on the crossovers indicate late 1981.







After researching these, mainly on here, the first thing I did was to Araldite (Epoxy glue) above and below the woofer magnets, to prevent magnet slip.



Don't have a pic of the glued magnets, but I'm sure you can use your imagination.

The next step was rebuilding the crossovers. After more research on here (thanks guys), I purchased Solen 33uf for the bass cap and Sonicaps for the tweeter. Also replaced the cement resisters with Mills 5W (Had already ordered these before finding out most use 12W, but hey, the old ones are 5W, so shouldn't be an issue.








So, happy days. The speakers are a match made in heaven with my Yamaha CA-620 integrated amp (only recapped the filter caps), and Technics SL-1400 turntable.

I'm playing Rattle Snake off Flying Microtonal Banana by King Gizzard and the Wizard Lizard (say that six times fast) and these sound glorious.

I don't know how to describe the change of the crossover recap, slightly cleaner top end, and more defined bass. And "Haunting Mids" LOL.

Anyway, i'm not selling these anytime soon. It's also HNAD, as I just bought a Yamaha CA-1000 which works, but I will give it a birthday first.

Good afternoon ladies and gentlemen. This thread is dedicated to....well, read the title. Pretty self explanatory.

Today, I measured the distance of the subs/speakers to the listening position down to 1/8 of an inch including the toe in and will be messing around with dialing in the Rythmik F-25's.

What have you done for your rig today?

Throw em here and lets admire each others bikes! I know threads similar have existed in the past but I can't find them.

Today is new bike day for me. Picked up this Felt F40X cross/gravel bike off ebay for 750 (2018 model) for a cheapish commuter bike on these crap NE roads. Nice to have something that I won't be afraid to get scratched up and has bigger tires for more comfortable commutes. Tiagra groupset with Tiagra hydro brakes. New tires and Prologo saddle on the way. Trying to hunt down an affordable carbon seatpost as well





This is the road bike. Carbon Felt FR5, 105 Groupset and Mavic Ksyrium Elite wheelset

My amps generate so much heat that summer listening becomes unbearable. I could use the A/C, but that runs up the electric bill, and negates the solar savings. So, this year I tried something different. Low tech, but it works.

An acquaintance of mine's 7 year old grandson was in a terrible accident on Monday. I don't know many details, but I do know that he was in a side by side ATV that crashed. His main injuries are to his legs, his right leg in particular. According to his grandmother, it was "filleted" and at this point is still in that condition. He had his second surgery this morning and it did not go as well as had been hoped as the doctors had to remove about 5" of muscle and tissue in the right leg. Thankfully his injuries don't appear to be life threatening (though you never really know), but he is still very much in danger of losing his right leg almost up to the hip. Prayers for this little guy and his family would be greatly appreciated. I just can't imagine sitting in hospital room with my son in this condition. It breaks my heart.

Wyred 4 Sound W4S DAC-2

Very versatile DAC. This DAC has digital volume control, via remote and buttons on front faceplate. Read the many glowing online reviews. Well taken care of, light signs of usage and is in very good condition. See pictures for more details. For disclosure, not sure why but the remote is a little sticky to the touch. I believe it’s the material used on the remote and perhaps it’s because I had previously stored the remote in a plastic bag. It doesn’t bother me and it works perfectly. Other than that minor issue, the remote is in very good condition. According to what I read on hifipig.com review on DAC-2v2, W4S was added to Logitech Universal Remote database, so that ubiquitous Logitech universal remote found in most audiophile’s listening room can be put to even better usage.

The good news is this DAC can be factory upgraded if you so desired, to W4S DAC-2 DSD SE, DAC-2v2 etc. Check out W4S website for the upgrade options and pricing. Instead of buying a brand new DAC-2v2, one can buy mine, send it in to W4S for your desired upgrades, save a bundle and get a fresh new warranty to boot.

Selling off a secondary system, hence the sale.

Include remote, user manual, power cord, sealed USB cable and W4S CD (latest driver available online). I have obtained a new original double-box factory packaging from W4S to ensure safe shipping. Will be listing a matching W4S STP Pre-Amp.

Price: $595. Shipping via Fedex Ground. Flat shipping: $25. Payment via Paypal F&F or add 3% Paypal fees. Will also accept USPS M.O. from established forum members. Local pickup welcomed (SoCal).
