I only just found this video after owning the ARF-51s for a couple of months. Yes, I have the really expensive floor standers which sound exactly the same as the bookshelf version. It's a really long story but I got them half price from an audiophile who loved them at a show but in his £50,000 system couldn't beat out his £7000 speakers. So I got the floorstanders for less than the bookshelves with their stands.
My previous system had a 20 year old pre amplifier, Audiolab 8000c, 2 x 20 year old power amplifiers from Rotel, a pair of Q Acoustics 2050 floorstanders and a Cambridge Audio DacMagic getting music from my computer. Two years ago I upgraded the DAC to an Audiolab M-DAC and realised the rest of my system was holding me back.
I got interested in the speakers Elac where producing, then heard about the Navis bookshelves and started saving my pennies to get a second hand pair in a few years. When the floorstanders came up I had to jump at them. As I said I hadn't seen this video before but John Darko gave an identical review in terms of how good these speakers are at taking advantage of better quality sources, in particular better DACs:
I'm now very close to a system I'm going to stick with but my my final issue is due to problems with the USB input of the Audiolab M-DAC. Right now I use my Mac Pro with a USB3 card to feed it. I want to move to either a Mac Mini or a Ropieee to make use of Roon and listen to music without having to turn on my desktop computer. Any other USB source causes the M-DAC to produce popping sounds, there's a USB Buffer displayed on it's screen and when the buffer level drops you get a pop.
So this is how I found these forums, I heard about Topfield DACs and found more information here than anywhere else. I'm now really close to buying the Sabaj D5 as what I've read shows it has a good USB input and it has the balanced output I want for my speakers. The one issue I'm finding on this forum is a very negative attitude from some people towards the ability of a DAC to improve an audio system. The 2 reviews of the Elac show very clearly that these reviewers believe the sound from the Elacs was improved by upgrading the DAC feeding them. Should I listen to the reviewers or a couple of people on a forum trying to convince me a USB stick DAC is just as good as a £400 Sabaj D5?
There was a point in the video around 7:45 where he said the Elacs aren't revealing and I was close to walking away. I'm glad I didn't as he then came back to explain how much they'd changed with another DAC.
They were given a very poor review by Z but it's become obvious to me this guy likes super bright sound. The Elacs don't do that, but time and time again I put on a track that I haven't heard for a while and find myself listening to the whole album, they make me enjoy my music more than ever.
