You know, you’d think that after I grabbed my Pioneer HPM 100 Speakers, I’d be listening to them nonstop. You’d be wrong. I ordered some speaker stands that would support those behemoths. They are just sitting there looking at me with their unloaded speaker stands. I think that what I am going to do is put my Carver CT-3 preamp together with one of my Carver TFM-25 amps and pair those with my M-50’s and the Pioneer Elite 400 DVD changer. This will allow me to test several things – first, does my TFM 25 really have a bad channel or is it the receiver? What is the best way to hook up the M-51 to the preamp? What is the best way to utilize my equalizer and my tape deck?
AXPONA was an experience to behold. As far as the conference was concerned, there was a lot going on -a large hall that housed local guys doing sales of vintage audio and consignment, vintage repair services, ultrasonic vinyl cleaning machines, cable sales, record sales, and various vendors. There was a hall that was purely headphones and headphone/turntable preamps and also a hall devoted to car audio. In addition, there were lots of listening/reviewing rooms on the first 4 floors with dealers, components, and their accompanying speakers, and in addition there was 12 floors of listening rooms for audio.
There were 2 pair of speakers really stood out above all the rest. One was the Avantgarde Mezzo speakers, and the others were the MBL Speakers. These 2 needed nothing in my estimation. I sat in the “sweet” spot area of almost all the speakers when I was listening. Some had interesting experiences with imaging, separation, range and clarity. Some speakers were better than others. Some sonic ranges were better than others – some, you’d definitely need an equalizer. Some you’d need to augment with a sub.

Everything else were varying degrees of ho-hum. That said… there were 2 other standouts from the pack – a pair of bookshelf speakers that sounded better than most floor speakers – Elac (the company name) that made a pair of bookshelf speakers that I understood to be less than 1k$ and they had a better range than most of what I heard – both bookshelf ad floor standing. I will have to find out what the others were, but they were floor standers and while they didn’t impress me by sight, suffice it to say that their sound really impressed me. Thankfully, I actually know the sales guy (well, my buddy Joe does).
Today AXPONA starts and I will be attending tomorrow with my buddy Joe. We have been friends since sophomore year in high school. Which is saying “an effing’ long time”. I am looking forward to seeing/hearing some of the more highly exotic and esoteric speakers this weekend. Maybe I’ll see my other friend “Joe the dentist” there. He apparently purchased some crazy expensive speakers, but I haven’t been over to his abode to check them out yet. I am sure I will see a lot of “snake oil” salesman at this show. It really doesn’t matter what you spend on audio, you like what you like. I remember in college, we had 2 guys (Tom and I) whose rooms backed up to each other and another guy on the floor who spent some big dollar amounts on audio equipment. The guy whose audio cost a lot (I can’t remember his name) never sounded well – his amp was so big that he kept damaging his speakers and they would rattle and hum (sounded like shit). And we used to have stereo wars. Tom and I both had good setups with better than average speakers. However, Tom’s speakers were highly efficient, and he could mop up the floor with me. Needless to say, I never won stereo wars – my speakers while having a better range and separation (imaging) were not even close to the efficiency of his speakers. I would have had to have a 1000-watt (RMS) amp to even begin to compete and probably would have blown out my speakers. He had rock and roll speakers, and I had classical music speakers. His were about beating you over the head and mine were about inserting the knife. His had horn tweeters and mine had a beryllium ribbon tweeter. His had no midrange – the horn did double duty, mine had a boron coated midrange, we both had woofers – his was a paper cone with a passive radiator on the back, mine was a polymer woofer. The difference was really efficiency – his was 90dB efficient and mine was 86dB efficient. Which as a physics major and understanding electronics, I should have figured it out. For every 10 dB in volume rise, I would have to double the power. Meaning if we start at 1 watt – mine would produce sonics that would measure 86dB. In order for me to get to the next dB, I would have to turn it up to 10watts. 87dB? – 20 watts would net me 88dB?
It’s a high of 48 degrees today (last day of March) with yesterday’s high of 75 degrees. Saturday afternoon, we went and saw a Fleetwood Mac tribute band at the Lyric in Blue Island. It was also a nice venue for the mobility challenged.
One thing this weekend (on a different note), that I didn’t expect was for it to be such a pain in the ass to do my taxes with software that I wanted downloaded – everything now is so cloud centric that I had to hunt for a download solution from H&R Block. I have zero confidence in cloud-based software that also protects my personal financials. I wonder how others feel about this. And no, I’m not allowing comments. It was a rhetorical question.
One other thing that I didn’t anticipate (on a separate, and different note) was that when I bought and hooked up the digital ASU/XLR cables that connect the NAD M51 to the NAD M50, my audio sounds way worse. The musical resolution is crappy, full of static, and heavy on one channel. Hopefully, my receiver isn’t dying on me because the first symptom would have been the one channel on the preamp dying. Which may mean (now that i think about it) that the amp is actually good, and the receiver is garbage.
So, I got my NAD M52 Digital Music Vault (ordered from Germany – vintage 2014 tech) this week. It’s a glorified NAS (RAID 5) server that specifically supports the NAD M50 Digital Music Player (vintage 2014). I also happened across the NAD M51 (DAC and Digital Preamplifier also vintage 2014) to complete my NAD suite. We shall see how it compares with the Vault2i from both a convenience and a performance perspective.
So, I’m happily burning CDs on Friday, and I go downstairs to find a box and start packing up my tweeters to send for refurbishment, and I put on some music… I hear that one of my channels is out on the amp (TFM-25). Well, I see it occasionally trying, so I turn off that amp, and listen to one of the others. Figuring that I will look into it tomorrow (Saturday). Oh, and buy the way, I can’t get the powered Klipsch sub to work with the Klipsch speakers upstairs on the Pioneer SC-07 receiver. I don’t think it’s anything except that I can’t use a preamp sub RCA out connection with the speakers functioning off the regular amp. I guess it’s just me not understanding the limits of the receiver. I may have to ditch the Pioneer for an old-school 60W Yamaha receiver with way less options. I don’t really need all the “bells and whistles” with all that power anyway. However, now I have to send the TFM-25 in for service early. I was going to do it anyway, but now I have to do it sooner rather than later. I think I’m going to get the “Cadillac” refresh on this first one so I can see what all the mods are up to. It’s the one amp that I use the most – it powers the Ohms downstairs.
So, I put in my Energy replacement (v.1989) tweeter yesterday and I noticed 2 things. First, the replacement tweeter (v.2020) that was in my other speaker has better sound and fidelity, second was it was louder so it’s more efficient! That’s why it sounds so much better. The downside to replacement tweeters (v.2020) is 2-fold, first is that the original tweeters (v.1989) have different connections, so the stock connectors won’t work, and second the wires are so short coming from the crossover that I have to be careful replacing the connectors, oh and did I mention that also there is no marked polarity on the old tweeter- wtf? Maybe I’ll ride with the new/old tweeter (v.1989) until it craps out, send the pair in for rebuild in the meantime. When it craps out, I will replace it with the new replacement (v.2020).
Oh, and either my left channel on my amp is failing, the cable is failing, or my receiver’s left channel is failing – ugh! It’s not the wiring – at least I know that. It’s always something.
So, when I get home today, I am going to do 2 things – first, replace my Energy 22 Reference tweeter (I just got an extra one used via eBay) and second, pack up my other tweeters and get them ready to ship off to the guy who will recondition them. And while I’m doing that listen to some music. I need to treadmill it and sling some weights around – I have MEPS to get! (flipping MyZone). I am also doing a class centered on electronic circuits – it’s funny how much stuff I forgot. Also, it’s kind of interesting using this software called Tinkercad that can do some of the circuit analysis – it’s all virtual! It kind of floors me – yeah, I know that I should expect things like this, but I remember doing all this stuff by hand – meaning with pencil and paper. My original electronics teacher from COD was an engineer at Bell Labs and was on one of the teams that worked on a part the development of the integrated semiconductor. He was probably in his 70s at that time. He had some interesting tales.
Just when I thought I wasn’t going to find an M52, I find one – new, vintage 2012 and in a box nonetheless! Whoda thunk? I’m happily going through and burning my CDs to the Vault2i. I have a crap load. Now I’m beginning to wonder, do I have enough to contemplate getting rid of some Apple products and pick up Roon? Supposedly, you are supposed to have over 5k of songs in order for it to pay off. I’m kind of happy with BluOS and do I really need or want to stream to my iPhone? I’ve lived with being able to stream to any device within the confines of my house. Do I really want or need another 15$ per month service? Do you ever get rid of a subscription – I really need to think on this? Hmmm…
On a separate audio note, I subscribed to “Audioholics” which is an audio blog site.
I was thinking that it wouldn’t be so difficult to find a NAD M52 digital music vault for my M50 digital music player. Crap was I wrong. For the past 3 years, it seems you would trip over them (per hifishark history). This year, they all reside in Germany, and no one wants to ship to the US. Save that guy on Reverb who wants to charge what it would have costed new. BFD, he replaced a drive – so what (it’s a flipping RAID array). Maybe I’ll try reformatting my RAID array again and see if I can get it to connect. Nothing ventured, nothing gained. Yesterday, I fired up the baby advents again – I forgot how nice they sound. Also, today I got a replacement tweeter for the Energy’s (below). Hopefully I won’t be sending this one for reconditioning any time soon. I have 2 pair now to send.
