To be honest, this caught my attention. However, I have avoided to buy 2-channel SACDs for the following reasons:

1) There are not difference between CD and SACD except for better sound quality
2) Personally I prefer SACD in multichannel and perhaps it will be impossible to use DTS Neo:6 surround decoder without any loss at the original DSD quality

I need some information about Exton's "Laboratury Gold Line". How this collection differs on the original releases? Reportedly these recordings were so-called "one point microphone versions". What does this mean? Do you have any listening experiences?

But Mahler's 10th on SACD - looks pretty interesting, indeed!

Good gracious Luukas, what a can of worms you have opened...

"There are not difference between CD and SACD except for better sound quality"

Surely that is the raison d'être of SACD in stereo or mch!

Exton discs are amongst the most advanced and realistic sound recordings available today. They are expensive but no collection should be without at least a few amongst their numbers.

Well, I just wanted to tell this fact once more. However, I have listened to these Mahler/Inbal albums on Spotify. They seemed to be very compelling and satisfying sets, indeed.

I own both the regular and the one-point-recording of the Inbal Exton 10th.

The one point recording was recorded with only two microphones placed about a metre apart just above the conductor. The idea behind this is that the sound of the orchestra will reach the microphones without time delay.

In a "regular" recording numerous mikes are placed in the orchestra., causing the sound of, for instance, the violins reaching a mike near the violins first and reaching a further placed mike with a small time delay. The various time delays need then to be edited out in the studio as much as possible before release.

Both recordings of the Inbal 10th sound similar. I've noticed in the regular version that some instruments sound more close to the listener than on the one-point version.
(probably due to spot-miking in the regular version.)

The only reason I own the two recordings is that that the regular version was released first and I had already collected the other one-point recordings in the series.
(If you are new to this series just choose the one-point versions - no need to own them both.)

I'm very fond of Inbal's Mahler. I've collected his 80ies Denon Mahler cycle on blu-spec cd and have also collected his two Maher cycles for Exton. (and the odd disc on Fontec)
In the course of listening to the Exton Inbal Mahler discs I observed some strange noises however cropping up here and there => Inbal likes to (sometimes) hum & sing along to the music. I don't mind this too much, but your mileage may vary.
