Half-Speed Masters - are they worth double dipping?

Save your money. Buy a nicely restored open RTR. Record your original vinyl. Your recording will sound better than the original album, because of a greater dynamic range with tape.

Record your original vinyl. Your recording will sound better than the original album, because of a greater dynamic range with tape.

The dynamic range of the tape recording can't possibly be greater than the LP from which the recording was made.

It is if you are near a radar tower while doing these R2R recordings. I love the R2R crowd. Yep the sound is fire. But every single other aspect is nerds. Unless you are in the music biz, these things are giant hassles. So many moving parts. Never again. But to all the R2R heads—keep fighting the good fight. I’m moving on to hires streaming and still loving my vinyl. I don’t love most modern 1/2 speed redos. Not worse, just not better for another $50. That said, always open to hear one that someone else thinks really shines, so I’ll monitor the thread like the music ones. I agree with the 45s rhetoric as well. Punchy. But not a ton pressed in 45 anymore. I tend to trust the original engineers so if they are involved I’ll take a look. Cool topic! 

@cleeds I believe you posted a similar comment in a previous thread about vinyl having a wider dynamic range. I've checked the DR Database and I cannot substantiate that claim. Can you provide a few examples of viny releases of the same title having wider dynamic range than the CD?

My research indicates that at best there is not a good correlation between dynamic range and format. Generally, however, it looks to me like a later remastering typically has a wider dynamic range on the CD than the vinyl.

First, and foremost - EVERYTHING matters.

By reducing the rotational speed of the disc by 2x, you double the amount of time that the cutterhead has to remove the material.  Consequently, there is an inherent increase in cutting accuracy.  When a stylus traces the same groove, it is more often exactly where it should be to reproduce the given frequency/sound - again, more accurate. 

This principle applies to the entire recorded spectrum - highs, mids, and lows.  In the attached article (below), an Abbey Road recording engineer states that cutting at half-speed is 'mind-numbingly dull ', but the process results in a much better sounding LP. (> @bdp24 - perhaps Bernie Grundman has concluded the boredom is not worth the time it takes for the improvement in SQ ;-).

That being said, if a crappy recording (say, compressed, dull microphone, cheap wires) is re-cut at half-speed, you may be disappointed in the result.  Remember, EVERYTHING matters. I have both fantastic -sounding and crappy-sounding half-speed LPs.

Yes, there are many other techniques to improve LP SQ, including direct-to-disc, 45 rpm, better quality vinyl, etc. and each can be independently employed.  In theory, you could have a half-speed mastered LP, pressed on uber-vinyl, that plays at 45-rpm.  

Regarding the digital vs. analogue issue, I find the transducer plays a prominent role in the SQ. 

For example: I have the same recording in both formats - simultaneously recorded on Analogue tape and Digital tape. I find a very good TT cartridge (my Hanna ML) can transform the soundwave-medium (mechanical to electronic) better than an average CD player (my OPPO, digital to electronic).  Consequently, the LP sounds better than the CD every time I compare the two. (of course, I am also hearing differences in tape-heads, etc.)

As an aside, my main system has a pretty good CD player as well (Ayre), and the SQ is closer to that of the LP.
