Is this in line with what is being discussed?http://www.erseaudio.com/Products/ProtectionDevicesI was looking at those. If there is enough interest we should start a new thread on this topic and evaluate all the possibilities, fuses, relays, polyswitches, filament, and the pros and cons of each.Roger Link to comment Share on other sites More sharing options...

The poor man bought the set for $9 and got to listen to them for a year before his amp fried one of the woofers.http://www.classicspeakerpages.net/IP.Board/index.php?showtopic=7051I was actually looking for a reference to what happens if a speaker is plugged in to an AC outlet but did not find it.Need to put my fuses on before putting the AR's back online Roger Link to comment Share on other sites More sharing options...

owlsplace Posted March 21, 2015 Report Share Posted March 21, 2015 So what amp are you rocking now? I'm confused as to where we are at in that regard.Well, its me and Kent on the Adcom 555II, at least until I can get back with my SAE and/or mod the Adcom. I definitely prefer a warmer sounding amp.I did find the reference to firing up speakers on 120vAC in some of the AR literature. Definitely not a good idea to use line plugs on speaker wires Roger Link to comment Share on other sites More sharing options...

Definitely not a good idea to use line plugs on speaker wires Sadly, there are a LOT of YouTube videos showing just that. The first time I found one I was looking for info on some classic speaker and saw a vid of some idiot blowing them up for giggles.

DavidDru Posted March 21, 2015 Author Report Share Posted March 21, 2015 Yes, the AR5 may be one of the best items on that list.Kef's depending which model.Maybe one if the nicest items on there is the Sansui 5000x if someone was in want of a vintage receiver at 60w/ch. Price dependent. Link to comment Share on other sites More sharing options...
JKent Posted March 22, 2015 Report Share Posted March 22, 2015 When would you use the FNM-8/10 fuse with the AR's?I ordered a dozen FNM-8/10 fuses and fuse holders so if anyone needs a couple send me a PM.Kent Link to comment Share on other sites More sharing options...
stan461 Posted March 27, 2015 Report Share Posted March 27, 2015 Over the years I have heard only a handful of setups that made me sit up and take notice.Sometimes it's just the way things strike you, your in the right mood or the stars are just aligned right.Anyway, one of those euphoric moments occurred was when I visited a co-workers apartment for a listening session.The setup consisted of Mirage M3SI speakers, Acurus A250 amp, Adcom GFP565 preamp, California Audio CD player, MIT interconnects and MIT speaker cables.What I remember the most was listening to a CD of Tchaikovsky's 6th symphony. The presentation was lifelike. As if the musicians were right in front of me. No breakup at high volumes. Simply breathtaking.I wound up buying the Acurus A250 from him about a year later and he replaced it with an Aragon 8008BB.The Acurus sounds great with my AR3's and AR3a's and handles the bass with authority.The relevance to this thread is that the Adcom GFP565 was part of the chain.Could you do better? For sure. But the Adcom did it's job extremely well.Although 10 years have gone by, I vividly remember the experience.He told me that he spent a fair amount of time moving the speakers around until he was satisfied he found their best positions.A 3' X 4' sheet was hung on the wall behind the speakers.Other than that, the room was not treated with acoustic materials.

I bought mine new in 1993, along with the matching L10 preamp. I mate the combo with a very revealing pair of Martin Logan hybrid electrostatics (completely passive) and get crazy smoothness, detail, depth, width, and control. I once heard a similarly powered Aragon amp, which had even more bass depth and control, so that's why I give the amp four stars instead of five. After owning the amp for 20 years and running it through the same power conditioner the whole time, I finally got a wild hair and wondered what it would sound like plugged directly into the wall. Well, I did that, and then my wife and I laughed out loud. The transparency increased by a whole lot. It wasn't subtle. Then I almost cried knowing that I spent 20 years with sound that was not as good as it could have been. Anyway, it's like I have a whole new amp!"BradleyP a Audio Enthusiast on AudioreviewIt's been interesting looking at amp choices after having been out of the scene for around thirty years. A lot of changes over those years mostly focused on the business cycle. Audiophile has always had the connotation of being out-of-the-reach of ordinary mortals; however, we all dream and some us actually try to follow our dreams. That is what makes life interesting.In a previous post from years ago on the same topic RoyC recommended Audiosource amps. They are in the three figure range. Audiophile these days is in the four to five figure range. So what does Audiophile mean these days, perhaps a new topic for conversation Roger Link to comment Share on other sites More sharing options...

I already have the Adcom GFA5500, the Dynaco ST400, and a Pioneer SA9100 (albeit in the shop). Plus some Pioneer receivers like the 737, 636, and 1000ta.I don't need it but if you think it is a great deal.......my guess is that it a lot like the 9100.

DavidDru Posted April 3, 2015 Author Report Share Posted April 3, 2015 Yeah, I have the TX9100 tuner too. Picks up everything.Many 9100's of their current age are having an issue with the protection fault tripping. There are numerous threads on AK Pioneer section dedicated to helping diagnose and find the failing parts. It seems like most of them being aging out issues and are hard to find. My tech has thought he had mine fixed a couple times now and I have a bag of caps and resistors he has replaced to no avail. He has many hours in it and fortunately won't charge me any more until he figures it out. I think he is taking it personal at this point, but he just does not prioritize it so it has been at his shop for quite a while. I stop by every so often to remind him about it and convey how much I miss it etc just to needle him a bit for fun. Link to comment Share on other sites More sharing options...

Probably semiconductor fail so would need to alternately heat/cool components until the culprit is found. Link to comment Share on other sites More sharing options...

VintageMan Posted May 26, 2015 Report Share Posted May 26, 2015 My AMP is a Marantz 4270, running 70W at 8-Ohm.As my AR3a and AR3a Improved will be ready to use this week I discovered that my 4270 cannot run 4-Ohm speakers when in Stereo mode.I love my 4270 and will not part from it to run my AR3a's.So I bought a SONY TA-N55ES.Looks:Specs:I can still use the 4270 but when playing the AR3's I just switch on the Sony connected to Front Pre Main Out of the 4270.

michiganpat Posted May 26, 2015 Report Share Posted May 26, 2015 as long as you don't have 4 speakers hooked up to the 4270, it should handle the 4 ohm load of the 3's just fine... Link to comment Share on other sites More sharing options...

If so, leave it in 4-channel mode and just use two channels. Or it may be possible to drive four 4 ohm speakers in quad mode.I have seen a 2270 drive four JBL Century 100s to chest pounding levels with no problem -- a rather memorable experience from 1970's Germany.Roger Link to comment Share on other sites More sharing options...
