John Curl's Blowtorch preamplifier part II

I have just listened to James Taylor LP Sweet Baby James commercial 1971 issue. Perfect recording and mastering-clean, clear and dynamic. I advice Pavel to find it and if it is caricature.
An advice for Mr. John Curl: Have your Linn Sondek motor re-lubricated. Your playback will be better still.

Grew up with this in the house. Excellent album. I have it on CD and use it as one of standards. I turn it up until tape hiss competes with ambient room noise, then back off the volume just a little.

ref streaming, BBC radio streaming is now better than the DAB multiplex. Although streaming is a horrendously inefficient way of delivery UK has backed itself into a quality corner over DAB bit rates. Whilst BBC calls their streaming service HD its only 320kb/s. BUT the quality is better than FM or DAB. The sheer quantity of live music esp on Radio 3 means at times I do consider just having that on all the time. This week the Berlin Phil doing a week of sibelius concerts every evening :) It's a good time to love music.
 
For now my 16/44 setups work perfectly well with all the clarity, instantaneous dynamics and emotion anybody could want.
I am doing some special tricks in my system which bring out quite stunning source sounds separation, side and depth information/imaging, rock solid pin sharp centre imaging, and timbre realism.
In other words, every instrument/effect in a recording has it's own space and can be discerned and followed perfectly easily.
Some recordings are a special delight as regards individual/overall sounds quality and production values such as interesting placements and panning effects and depth effects etc.
Some older rock/pop recordings that I could not stand can take on a new life and become enjoyable, really enjoyable.
Mic placements are perfectly discernable, so is absolute polarity of individual sound sources.
ELO tracks are very good test material in this regard - because the recording technology was the very average equipment of the day, and a lot of production work was done these recordings can be hard to unravel, easily come across like AM radio fodder. Typically a very high standard of replay is required before the production "spaces" come to life, and the music manifests as a symphonic creation.

I see your point with streaming that it opens the doors to much more content, but I still am hearing of folks complaining in the US about local FM getting worse instead of better, but understand that there are many reasons why, even with IBOC. Do you have any experience with FM IBOC performance?

Thx for looking Scott, I guess I will have to go with a multi-part solution.
So far, I figure I can use the Max9723 and have to figure out on a mux. I realize that relays can be used but are expensive, takes way more area and draws more power unless I use a latching type. Presently I am working with a 5 & 3.3V DC supply. Any suggestions, it does not have to be i2c controlled?
Actually MAX14778 looks pretty good!! but is expensive at $7.23 single qty
Like to try and stay away from a negative V supply, even though I do have one available, for my LCD bias, now using a TC7660, but will eventually cost reduce and replace with a PWM pin from the Atmel xmega MCU.

Can't help much here our guys are just not interested in the consumer end parts. Too bad we can't seem to productize our optically driven MEMS switch though we do have a patent now. I actually used the ideas in my Linear Audio article and stacked 100 tiny photo diodes (~55V total) to generate the voltage to turn on a MEMS relay. Works on a mA or so and fits in a small SO package.
 
In contrast when listening to my system with other recordings, I often catch myself unconsciously tapping my feet...overall I get exciting involving immersing sound, no falling asleep !..
Unfortunately, this sort of comment has become a badly corrupted cliche - but the sense of it is still fully valid. Music either turns you on, or it doesn't - no matter how "driving" the pulse of the track might be, if it sounds like poo then it's not going to do it for you ... but, if the flow of the music resonates with one internally then one's body will react to it automatically in some fashion - say, with classical your head will sway slightly with the rhythm - it just happens, part of the human condition ...

If listening to music is an analytical exercise, then the system has failed to do its job - the music should carry one away to another place, that's how I see it.
 
SY seems quite proud of one of his home recordings..a guitar soloist, Peter Mulvey - Knuckleball Suite.
Perhaps I hear it differently, but to me it's hopelessly wrong.
The vocal and guitar sounds are overly distant, far too much room sound with some peaks/resonances, and a disturbing early reflection that intrudes strongly on one channel.
Overall to me it's also lifeless, and leaves me bored/cold.

This does not necessarily have anything to do with the technology. As I said we are not running a recording studio or a business it's true amateurism at its most basic meaning (sorry I don't mean to speak for SY but we did do a session together). The question is take the same basic electronics and get someone who knows about room treatment, etc. and who basically has done this a 100 times before and what do you get. I got some very constructive suggestions concerning the early reflection issues, something a rank amateur might miss.

JNeutron,
I have some clock questions for you as I have a couple of grandfather clocks not running that were supposedly fixed but don't run, Where to start? I'll PM you when I get a chance.

On the earlier subject of the Focal speaker I am in total agreement, just horrendous high frequency response out of those inverted dome tweeters. I have seen independent testing showing some horrid resonance in those tweeter. not something you can listen to for long. At the same time they do some really silly things with magnets just to be different. Why they think a bunch of individual small magnets placed around the back plate and front plate is an improvement over a normal magnet is beyond comprehension, just more marketing hype with no real substance. Not a fan of any of their foam cored cones either, not great designs but they do make things look nice, isn't that all that counts.
 
dvv the restaurant down the street had MAVŽELJ on the menu tonight, do you think it was authentic? Boil pork head scraps and lungs and brains separately. Chop them. Add cooked polenta and spices. Chop onion and sauté and use them as larding. Make fist-size balls and wrap them in pork net (caul fat) separately. Place balls in baking mould and bake.

My family came from Corinthia right where Italy, Austria, and Slovenia meet. We had polenta far more often than pasta.
 
SE,
I'm wondering the same thing. Are we talking about a service like
Spotify or what here. How is that digital streaming any different than a CD if it is bit for bit the same and at the same rate?

Yeah. Richard's talking about eliminating the disks, whether they be CDs or LPs. But unless the data is just magically appearing out of the ether, or someone is direct streaming a live concert, that data has to be played back from some sort of storage medium, which is most likely going to be a hard disk. So how have you eliminated any disks?

He already said putting it on a hard drive and playing it later is not there yet, I don't understand.
