It is a common modification for the TDA1541 DAC chips as it is generally thought to improve the sound. Google 'NOS mod TDA1541' and have a look at some of the hits. The TDA1541 is a bit of a cult DAC chip from many years ago and the players can be found at reasonable cost if you are patient.

I recently gave up an attempt to biamp my speakers - first, by passive, horizontal biamping, and then using an electronic crossover. I've gone back to ONE power amp and ONE set of speaker cables.
Funny you should post this! I've just done exactly the same thing!

To explain a bit further ... about a year ago I bought an Arcam Alpha 8 pre / power combo to bi-amp my Mission 752's and it worked pretty well I must say ... but I think I started to miss *something* indefinable from my previous amp!

So, out she came, my trusty Musical Fidelity A2 which I bought about 5 years ago ... marvellous sound! It's difficult to explain , but there is something just so *right* about this amp ...

I bought these some time ago, but the original earpads had gotten rather flat and anything but firm, much like a tired old pillow. :cry:

I thought about getting some cheap generic pads from China, but these are quite nice sounding headphones so I had to do some research but was fortunate to find some genuine Beyerdynamic pads even though they were much more expensive.

It helps to have a hairdryer to warm up the part of the pads that fit onto the headphone, to get them to fit over the edge but the results are well worth it. In some ways its like getting a tire on a rim. They are much firmer, but still very comfortable, plus they keep the sound in and the drivers at a uniform and proper distance from the ear.

The verdict is it's well worth the price and effort, and like getting a new pair of headphones. :mrgreen:

I'm still trying to get my system back running a year and a half later since moving here. The POS Sunfire Theatergrand processor crapped out, I changed out turntables, cd player ended up turning into a new multichannel player. Got new front speakers last week which are still in the box( I can not lift them out of the boxes) . Just got a power conditioner/ power strip so all the 120 v cords need re-routed in the wire management channels. Rear surrounds need wiring run to them. Projector needs hdmi cable run to it. Screen needs hung on front wall. Receiver needs set up for new speaker configuration. Everything takes 10 times longer when you have to depend on others to do it for you :(

A follow up to my new pads on my vintage 600 ohm Beyerdynamic headphones.

The new pads also came with some thin foam inserts that go in the center, over the driver but listening tests showed they sounded a lot better without those discs in there, so out they come.

I had a long listening session of several hours with the new pads though and they work great and also keep the headphone from moving around so much in addition to the benefits previously mentioned. =D>

I have a set of 1993 Beyer Dynamic DT990 Pro headphones that are the 600 ohm version. I put them up for comparison at the last headphone meet against the new models and several of us all liked the older ones the best. I put mine up for sale recently on Head-fi website so that I could get some low impedance models, but no takers. So I will just keep them till I die.

Currently I have 4 pair of AKG K240 'phones......and 1 pair of (circa 1980) K141 ---the latter are 600 ohm.....
Have to say.....I like the sound of the 141's BETTER!! I've done listening tests, comparing the 2 models listening to the same music, played through Peavey and Soundcraft audio consoles with a Behringer HA400 headphone amp....
Not to start a "war" --- but the 141's are the ORIGINAL Austrian-made units.....the 240's are from "Riceland"....!

I have an older pair of AKG K240 600 ohm headphones made in Austria which are sometimes know as the Sextett due to the design which is a similar design to the K141* I believe.

I am listening through my Sansui 9090 headphone output, but any good receiver or amp should work. I think the lower impedance types are a result of a need for such on smaller portable devices that can't handle 600 ohms.

* Just a follow up. The K141 used the same driver as the K240 Sextett but lacks the six passive radiators that surround it.

Originally, and like back in the 1970's, standard headphone impedence was 8 to 16 ohms, a few around 32 ohms.

The impedance on the Koss Pro 4AAA from the mid 1970s is listed at 250 ohms and the same would apply to the Pro 4AA. That 250 ohms seems pretty standard for many headphones by a lot of manufacturers.

It's been a LONG LONG time since I've last chimed in, but I've been so busy with projects this year. :-)

My latest project is a Pioneer SX-3800 restore. Not an electronic restore, but a cosmetic restore. :shock: I will post pictures soon.

Got the Magnepan 3.7 speakers unboxed and in place, Clements RT -7 speakers in the rear surround position and all Tara Labs wiring run and terminated.

After much planning, soldering, and heat-shrink tubing, here is my latest finished project. LED's in the pioneer SX-3800 function buttons, speaker buttons, and STEREO/QUARTZLOCK lights. I kept the incandescent for the ambient lighting as this receiver should look as original as possible.

I had a set of the Pro4AA's back in the early 70's up through about '82. Your right, the impedance was 250 ohms. The original 4AA's sounded great. I have not heard the current 4AA's. From what I have read they don't sound as good as the originals.
