Hi mr 10%, Wich of the sources do you think sound  best?

I use the Oppo for CD playback - rarely. The Oppo also plays direct to the Eclipse in DVD mode. 

The Melco is a cool music server but over rated and over promised in terms of what Melco said it could/would do and what it can. Useless control interface (touted as a music server you don’t need a PC for - I could do them over of false trading with that). However, stick it over the network and it’s works with everything.

The Vega G2 also picks up from the network, is highly controllable via its DS app and it just works. Can also act as a preamp for other connections if required so probably worth investing in if you have lots of 3 party gear to connect up. It’s also my Qobuz source (Melco should have done that).

Musically, I have only limited experience due to time away from work. However, I remember giving a bit of Mo’Horizons a bit of bash and noting that this routing seem to offer more “punch”, rhythm over the source coming in via the eclipse and Powerlink . The best I can describe is like wearing sunglasses on a fair day. The tint is nice (Powerlink) but seeing correctly without the slight colour or blur is a revelation.

Next week I’m home demoing the Leo clock (sharpened th3 sound a lot on a demo with some good-ish monkey coffins and I’m hoping the same will happen again with the 90s. Not cheap. Have to see?)

Would be interesting to her your opinion on core vs beosound 5. Beovision 7-55 MK1 red, Beolab 10 red. Beolab 50, all black. Beolab 17 broken ice. Beolab transmitter. Apple tv4 and apple express 2.

I have listened to the same track with the Core and the Beosound 5, at this point I do not hear a difference.

Hi there - I'm thinking of doing the same with my (soon to be arriving) 50s.

Do you have any issues using the Nucleus as server and streamer?

I keep looking at a Nucleus and a separate streamer / DAC to feed the 50s.

But not sure its worth spending 2k+ on a dedicated streamer / DAC.

Maybe Nucleus first, and add a streamer later if desired.

Anyway, any thoughts re quality and ease of use with Roon would be much appreciated.

Thanks

To BL90:

CD7000 using coax SPDIF (I might change to RCA-out to taste the flavour of the 1990s TDA1541 DAC).

Beogram 7000 using RCA.

Core using Toslink.

Doing a little testing, same track from CD sounds clearer and more detailed than the same tracks at 16/44.1 from Deezer HIFI.

.

 

 

Present: BL90, Moment, Core, BL6000, CD7000, 7000, Essence Remote.

Past: BL1, BL2, BL8000, BS9000, BL5, BC2, BS5, BV5, BV4-50, Beosystem 3, BL3, DVD1, Beoremote 4.

Oppo 105 connected as follows:

  • -> HDMI -> Beovision 11 -> Power Link to Beolab 90s for anything with video or in surround
  • -> S/PDIF - > Beolab 90s for all 2.0 PCM playback up to 192 kHz
  • -> XLR -> Beolab 90s for DSD materials (2.0 SACD and DSD files)

I've got the 90s with the inputs prioritised in the order listed above, That way they automatically select the S/PDIF input over the XLR when I'm playing PCM materials, and the Power Link wins when I turn on the TV.

No, the Beovision 11 isn't 4k - and the Oppo isn't either. Neither does either support Dolby Atmos. However, we don't watch TV much - so 4k is not a priority for us, and the Oppo has excellent performance - and too many good features for me to want to replace it with anything 

For testing & experiments, I occasionally use the following as well:

  • A Raspberry Pi running Volumio connected to the USB Audio input
  • An old Google Chromecast Audio with an Optical connection to the 90s
  • A Beogram turntable via a cheap third-party RIAA preamp into the RCA inputs. As soon as I finish making my own RIAA, that'll join the system and get used a lot more, I hope... (otherwise, I wasted my time making the preamp...)

Thanks Geoff.

I have my 50s coming soon, so have been pondering audio sources.

Cant quite decide between just feeding it Roon Nucleus via USB Audio to the 50s. I wont ask for comment re quality, as my guess is that its not something you have played with.  

Or as an alternative, using a 3rd party streamer/DAC unit  (Auralic, Linn etc) to the 50s.

The Linn streamer I'm looking at has both digital outputs (SPDIF), and analogue (RCA) outputs. I can connect the Linn to the 50s both of two ways. The Linn will output to both simultaneously.

1.   SPDIF (digital)  route the audio through my Beosystem 4 via Powerlink to the 50s, but wont then use the Linn DAC, but as a BS4 source can then be distributed multi-room using NL.   

2.   RCA direct to the 50s, will use the Linn as both streamer and DAC.

The Linn will output to both simultaneously, and I can chose which to listen to using the B&O app.

This may seem like an overly complicated setup, but cant quite see the downside. Both options allow me to use Roon, one digitally and distributable as a NL source through the BS4, the other analogue (via the Linn streamer / DAC) to the 50s, but for single room listening only. 

My question to Flere above was given his/her experience of just using the Roon Nucleus direct to the 50s via USB Audio (i.e. no additional streamer/DAC).

Anyway, looking forwards to the 50s installation.

Thanks

Sandeep

Side note question, what makes a good RIAA? I though it was all a standard they had to follow?! How can you tell which one is good/better/best?

RIAA is just a specification of a filter curve - so it's a measure of the magnitude response (what most people call the "frequency response") of the preamp - the gain of the preamp as a function of frequency at one input level.

However, this is only one measure of a preamp - and, more importantly, it's just a linear measure, which is one of the easiest aspects to implement.

Like any audio equipment, there are lots of other things to consider - the non-linear aspects like signal-to-noise ratio and distortion characteristics, for example.

Since I'm building my own, I can also optimise the output level to the expected level at the input of the device to which it's connected. This helps to maximise the signal-to-noise of the entire system.

One of the reasons I'm not finished designing my preamp yet is that I haven't quite decided whether it will only have the RIAA compensation, or if I should also implement some of its predecessors and competitors. This is because I have about 2 m of shelves of 78 RPM records in my collection - many of which were made before the RIAA standard. In those days, you had a selectable de-emphasis filters, and you just picked the one that sounded best for the record you put on. I also have some of the old Teldec Direct Metal Mastering discs, which didn't use the RIAA standard either.

Hi,

I never make any comment or recommendations on any audio equipment that I have not personally tested...

HOWEVER, I should like to point out that, when looking at streaming devices, you can't just consider the end-device (in this discussion, the player). You also have to consider the interaction between it and your network, the software running inside your NAS drive (if you have one), the streaming service and its local settings, and whether the file on the streaming service's server is identical to the original master or not...

I wrote a 8+1-part series of articles about these pitfalls that might help if you can't sleep. They start here:

https://www.tonmeister.ca/wordpress/2018/02/08/typical-errors-in-digital-audio-part-1/

If you go through all of these, then you'll understand why making any recommendation is foolish. My only advice is to find something you're happy with, and then never read another magazine or the Internet again. :-)

Cheers

I’m fairly confident Geoff, that if you ran the project to make a Beosound xxx streaming device, there’d be a fairly big uptake even from here.

AdamS:

Our Beolab 90s are connected to:

3. Yamaha CX-10000 preamplifer via the XLR inputs.

Plugged into the Yamaha I have a Marantz CD-94/CDA-94 CD player/DAC pairing, plus a Nakamichi TX-1000 turntable/SME309 arm/Clearaudio MC Essence cartridge through an Anatek MC1 phono preamplifier.



WONDERFUL equipment, especially the Yamaha preamp!
