Concord enters the 5 LPs box market

Marantz amp problem, sudden "gargly" sound
Kevin Bresnahan replied to Larry Kart's topic in Audio Talk
When B&W switched over their entire Nautilus line to diamond tweeters in 2010, the list prices were nearly tripled. As a result, the used market for the older Nautilus speakers without the diamond tweeter has spiked recently. If yours need work, I would definitely get it done. They are nice sounding speakers. -

The speaker wires are worth a shot (you could've used some cheap lamp cord as a quick check). I'll be pleasantly surprised if that's it. I still agree with most of the other posters that both speakers being affected sounds like an amp/preamp problem. Crappy luck if you just happened to blow both speakers together. I have heard stories of it happening from a lightning strike. I've blown a few tweeters in my day but never both at once. -
Marantz amp problem, sudden "gargly" sound

"Break up" sounds like it could be a tweeter. But again, it's usually a higher-frequency buzz like a loud mosquito. Did you ever get a chance to try different speaker wires? -
I'd pick the Vanguard myself. I'm a sucker for Renee's playing and she has Chris Potter playing up front. The Blue Note has the vocal band Take 6, Birdland has Ron Carter's "Great Big Band" and Smoke Jazz has vocalist Joanna Pascale doing a Monk tribute. Pascale's got a killer backing band so if a vocal tribute to Monk is for you, that might be a good one.

Marantz amp problem, sudden "gargly" sound
Kevin Bresnahan replied to Larry Kart's topic in Audio Talk
The B&W N805 is a two-way design. No midrange speaker. However, I agree that "gurgling" is typically not a sound reproduced by a tweeter, so i would suspect the low frequency driver over the tweeter. Of course, there could be a problem with the crossovers, but again, having both fail at the same time seems very unlikely. -

Nothing fancy about my EE degree, it's just a regular old EE degree. However, my career has long swung to the RF side of EE (GHz stuff) so circuit design and analysis is a distant memory. I can bias up and test just about any RF circuit you put in front of me. But don't ask me to debug your amplifier's schematic. I'm not the right guy for that anymore. Ancient history for me. I think sidewinder is referring to caps from the great capacitor scandal from a while back. The story goes that the formula got messed up for the gunk that goes into the cheaper Aluminum caps. He may be right that this is still a problem for all amps. I just have trouble believing that Marantz would have used these cheap caps, especially in their Reference Series. Maybe they did, but if they truly used them in a "low stress" circuit (their words), they should be OK, as the ratings for most caps are specified under full load i.e. stressed to the max. -

My Marantz PM-7005 is also hooked up to B&W 805s speakers too. We have a similar set up. I have difficulty believing that both tweeters failed simultaneously. FWIW, I have heard many blown tweeters and "gurgly" is not the sound I would ever use to describe what I heard. It is usually a high-pitched, almost painful buzz. The sound will break up and not be constant. I don't think it's your tweeters. BTW, if you do get the tweeters replaced, make sure to get the equivalent tweeter. B&W revised the N805 to the N805S right around the time you bought them. I think the tweeter is a little different on each of the models. I know the crossover is different. Maybe you could splurge and get a Diamond tweeter. ha ha ha... I don't think you could do that as the crossover probably isn't set up for that load. But it's worth thinking about. -

Marantz's Reference Series is not likely to use cheapie Aluminum electrolytic capacitors. They brag about this amplifiers design and proprietary components in their literature. They even highlight their capacitors as being "stress free". See http://www.vintageshifi.com/repertoire-pdf/pdf/telecharge.php?pdf=Marantz-SA-15-S-1-Brochure.pdf "Custom-made components inside the SA-15S1 include new stress-free electrolyte capacitors and the Shottky diodes, which also feature in the rectifier circuitry. The audio circuitry uses high-grade electrolytic and film capacitors, to ensure the excellence you demand from Marantz products." -

Their Reference Series is their top of the line. There is an Reference Series integrated amp with more power (PM-10), but it is still in the same series. http://us.marantz.com/us/Products/Pages/ProductListing.aspx?CatId=ReferenceSeries FWIW, I have a Marantz PM7005 integrated in use in one of my audio listening areas, actually the one I use most often, and it's been great. I don't think you need to pay the extra money to get into their Reference Series. The PM7005 or PM8005 are excellent amps. -

This is not a mid-level Marantz integrated amp. This model is in their reference series. Larry - just for the heck of it, when this garbling sound is happening, press several of the front panel buttons to turn on and off the Tone settings, turn on & off the speakers, press the ATT button to mute and un-mute the amp and the ILL button to turn on & off the display light. Maybe you have a sticky switch? I'm hoping on of these will clean it up. Also, for the heck of it, are you using a power strip? Is anything else plugged into the outlet adding hash to the AC feed? These digital amps can do weird things if lots of noise gets onto the AC feed. Can you plug it into another outlet? Maybe a filtered outlet? BTW, how are the speakers connected - bare wire or bananas? If you have extra speaker wire around, try swapping that in. Some speaker wire oxidizes with age and eventually could get very resistive. This one is a long shot in my book. -
This got posted recently: https://storms.ngs.noaa.gov/storms/irma/index.html I was able to zoom in on the house I rented in April and it looks to have weathered the storm pretty well. The pool looks filled with junk and dock is almost in said pool, but structurally, it looks like minimal damage.

Purging for a move - sales advice wanted
Kevin Bresnahan replied to Chuck Nessa's topic in Offering and Looking For...
The difference is that I knew the director of the nursing home. I gave the CDs to her personally and she told me that her residents were loving the music. -

Many (all?) libraries are very picky about what they take. The several large batches of CDs I donated to my local library ended up being sold for 25-50 cents each at the library's big fundraising sale. They didn't keep any of them for their music shelves. Apparently, there is very little interest from their patrons in them having a large Jazz CD collection. Just an idea... I was recently given ~2,000 big band/Dixieland CDs after a co-worker of my wife inherited them from her grandfather. She heard that "Kevin likes Jazz". I didn't know what to do with them (they were not my style) so I donated them a local nursing home where they have apparently been enthusiastically well received. -
What vinyl are you spinning right now??
Kevin Bresnahan replied to wolff's topic in The Vinyl Frontier
I haven't played this LP in a while so I pulled it off the shelf tonight. Nice date. I have the Analogue Productions 33 rpm LP (Analogue Productions Revival Series - APR 3006), which is mastered beautifully. Highly recommended if you can find it. -
It first made land in Florida at Cudjoe Key. For the last two April vacations, my family has spent a week at a beautiful house on Cudjoe Key. I have doubts that it's still there. It was right on the water.

My first concert was Kiss at the Springfield Civic Center in 1978 or 1979. It's a little hazy which one it was. I'm guessing January of 1978 because there were other concerts at that venue in 1978 that I'm almost positive I saw. I sat next to the stage so I got to see Simmons set up all the staged action. I saw him put the packet of blood in his mouth (how stupid was that?) and I saw him drink the flammable liquid that he used to shoot flames into the air (how much more stupid can you get?). Funniest thing was seeing him sprint back off stage to get the stuff out of his mouth after each performance. My first Jazz show was a tenor sax player who I've never heard of again (and can't remember his name) that I saw because he had Curtis Fuller in the band and I wanted to see Curtis. It would have been late in 1990 because it was right after Art Blakey died. I believe that the sax player was Curtis's student and I heard that he made a living playing the cruise lines afterward. I wonder if he still plays?

FS: Pair of PSB Imagine XB Bookshelf Speakers

The picture I posted is from a review of the Imagine XBs: http://www.audioadvisor.com/prodinfo.asp?number=PBIMGXB It looks like the Audio Advisor reviewer used a stock photo from a different model. -

I just got in a new LP as I finished up Herb Ellis. Now playing Paula Cole's new one: "Ballads"
