Actually, I have lived a more 'exciting' life than many here. I was not a 'nerd' or herded by my family to sit up and fly right. Many here seem to have led restricted lives, that have done them well over the years, but it leads to a 'constricted' point of view, especially about others, including me. Scott, were you one of those well-behaved kids who listened to his parents, and made steady progress in school? That would be my measured opinion of you, over the last 25 years that I have known you. It's OK with me, but I would appreciate it that you reduce your snipes of me, just because my lifestyle and opinions differ from yours.
 
Joao, I too, love analog magnetic tape, but it is REALLY HARD to get software for it, these days. Back in the day, I designed these monsters, and was very good at it, but the best recorded sound that I have ever listened to is DIRECT DISC vinyl. I had dozens of examples, before the firestorm, 19 years ago, and a wall of master tapes as well. All lost, alas, so I have to enjoy what is still available, and used record shops did come to my aid.

we have here in Switzerland / Germany the "Aanalogue Audio ***." with have a subdivision tape recording. They're producing new projects and distribute copies of them. Maybe this is somewhat for you...
 
Symphony No. 6, 4th movement, e.g.. Try it. And also Herreweghe conduct, PTC5186314 SACD.

Pavel, I'll look out for it, thanks. I assume you mean Gardiner's Beethoven, with l'Orchestre Revolutionnaire et Romantique? I heard him conduct Bach Cantatas a few years ago - and had the Monteverdi Choir achieve the most crisp & precise vocal ensemble I have heard.

If you enjoy big orchestral dynamics, the the Lanchberry I mentioned before (SXL2313) is extraordinary, or the Louis Fremaux reading of the Berlioz Grand Messe des Morts (EMI LP), in the 'tuba mirum' section (four brass bands strike up).

If these don't play right for you, may I pass on Jonathan Carr's Lyra recommendations for cartridge setup? Briefly, use a Wallytractor or Armgeometer* to align the cartridge with the greatest care and accuracy you can muster. Add (Epoxy) lead-ballast to the counterweight, so that the arm's counterweight is positioned as near to the pivot as possible - this is VITAL for securely tracking big orchestral crescendos! Also, use a stylus force gauge accurate and repeatable to better than 50ug. VTA is also critical, but must be set by ear.

The cartridge alignment makes such a profound difference, that I think it explains why many folks here believe the old Denon 103 is (nearly) as good as a fine modern line-contact stylus cartridge. The Denon has a simple conical stylus the makes it less sensitive to alignment, and therefore easy to 'fluke' the setup. The Lyras require the greatest accuracy.

* I use Keith Howard's template generator: 'armgeometer'

Freeware

and I recommend it, but only to folks who are mechanically highly competent, and able to avoid breaking the stylus as it rests on the template!

Yeah, that was amusing.

At the ETF, Mr Frank Blöhbaum demo'd his Thorens TEP3800 beauty and the Silbatone preamp, through a pair of exotic WW2 full rangers.
With a fine-looking Thorens TD124 model, and a Denon DL103 cartridge :clown:

I sat with Miss Schoener during the first night, when she set up her Garrard 401, said she needed an empty room to focus.
When she was finished at 07.15 AM, i said i'd turn in. The lady answered i was having breakfast first, then i could go to sleep (2hrs).
Priceless.

Homeless, as I was when I developed the comp differential jfet input stage in 1971. Lived in a 16 mm sound studio, when I could not find a girlfriend to sleep with. Those were the days! Beautiful women, on occasion, hard times, and a mind free to create, rather than put out 'fires' in the workplace. Sat on the dock of the bay, on occasion, didn't see Otis there, however. ;-)

Being without a roof over your head builds character, don't you agree?

It certainly changes your perspective, permanently. 😀

What's wrong with the Electric Prunes? If you read all the lyrics you would understand my comment. Sorry for any misunderstanding.
 
Cartridge set-up is a hassle, that is for sure. I used a Denon 103C and 103S for some years. Quite a good cartridge. I measured the spectrum of the 103S, and it is Fig.4 in my 1978 IEEE paper. Interesting peak near 160KHz on both the C and the S. Loaned my last Denon, a higher priced one, to Jack Bybee to use, when his cartridge broke last year, as I hoped to replace mine with an 'SL'. That fell through, unfortunately.
I would like to point out that exactly 69 years ago, the Battleship West Virginia was sunk at Pearl Harbor, one month before I was born. Thankfully, my father was not on the ship at the time, though he had served on it in previous years. I would say that he was lucky!
