Certainly this is a very respectable performance.
However, I feel obliged to comment on the sound of the timpani in particular; for example in the opening of the first movement just a few bars in and there it is, the classic CD timpani sound, well more like a garage door being slammed actually. The DG, Karajan of the same work is a good example of that dreadful noise - does no one care?.
There is, in fact only one recording of the Dvorak 9th that exists where the timpani sound clearly demonstrates the sound of wood striking skin, not only that but the sound quality in general is probably the best of any recording of the work.
As to the performance just glance through these extraordinary reviews:
"Engineer and producer Geoffrey Terry has captured Jiří Waldhans at his most colorfully magnanimous, a real cornucopia of sound." [Rating ★★★★]

American Record Guide
"The great historical recording of this work [Dvořák] is Talich's from the early 50s. This is as good a performance, and the sound [...] is far superior to the Talich. It has a lightness and clarity that is amazing for its age ... [This disc] is worth buying for both the Dvořák and the Novák."
-Carl Bauman, American Record Guide , July/August 2010
"These must be the best sounding recordings ever made in this acoustically troubled venue. Everything is bright, clear and rich, and the performances are outstanding. The Dvořák grips from the very opening and has now become my favorite version of the work [...] Highly recommended."
-Don Hansen, San Francisco on the BBC Music Magazine forum, 13th January 2010
"I've listened now twice to the Dvorak 9th on my main hi-fi system, and am pleased to count it as my favourite performance - direct, no putting an `interpretation' on the music, just presenting it as is. Thank you for preserving it, and now presenting it."
-Peter Stanger, conductor and pianist, private correspondence, April 2010
International Record Review
"[Jan Novák's] music has hints of Martinů, but also has real character of its own, and the work is well played here: I know of no other recording of it, and lovers of Czech music should try to hear it."
"...the live sound is excellent..."
-International Record Review, April 2009
"...the Philharmonic Dances are a fine example of [Jan Novák's] work, very well played here. Novák is still badly underrepresented on CD and I am not aware of any other recording of the Philharmonic Dances, so this is all the more welcome ... Again, the live sound is excellent, and this disc is particularly worth seeking out for the Novák."
-Nigel Simeone, International Record Review, June 2012
La Scena Musicale Online
"[Dvořák's 9th Symphony] Why am I listening to a 43-year-old live performance of a symphony I've heard more often than Happy Birthday? Because the Brno Philharmonic in 1966 are a real Czech orchestra, unlike the modern soundalikes, and the conductor Jiří Waldhans is unafraid to let his brass let rip in organic style. This may not be everyone's glass of Pilsner, but I found it marvellously refreshing."
-Norman Lebrecht, La Scena Musicale Online, 19th August 2009
"This [Novák] is music of welcome vitality and uninhibited brio."
"The recording quality is certainly first class and has real clarity and natural balance."
-Jonathan Woolf, MusicWeb International, April 2010
"I played Terry's recording of the [Novák] work repeatedly when the CD arrived-it's so full of life, one can't tire of it."
