Dave Lalin "The Audio Doctor" musings on the latest trends and gear. 

Why you want upsampling and upconversion in a server and why it sounds way better!

 

02-04-2020  One of Roon's and Jrivers best advantages is the ability to digitally reprocess your data.  With an appropriate server you can take for example a 16 bit 44k Tidal stream and reprocess that data stream to DSD or to reprocess to 24bit 192k, 384k, even up to 768k.

In our tests almost accross the board most listeners perfer DSD or high res PCM data streams.
The counter arguement is that if you start with 16 bit 44k sample you can't do any better as that  is the source. Going through Facebook we got a post that showed the Lumiere brothers first film shot in 1894 with a steam locomotive. The second video showed the same Lumiere video reprocessed using AI to create a 4k video stream out of the same video footage. 

The first video is the native source the second shows the reprocessed video the differences aren't subtitle even if you reprocess the native video you are able to extract a signifigantly higher quality image. We have been saying this for years even if you don't start out with a true high res source through the magic of computer reprocessing you can create a pseudo high res data packet that still sound far better than ifs original form.

Watch the video and see what you think. Sure it is always best to start with a true high resolution image but in the case of not having a true high resolution music fille the ability to use digital reprocessing can create a signal that will sound far better providing that your dac and server are up to the task.

Lumin X1


Lumin X1 latest Review like we have been saying !

 

12-13-2019   For many years we have been touting the Lumin products as being one of the best sounding and best implimented paths to creating a fantastic sound in your system.

We sought to be a Lumin dealer after the A1 came out and pretty much got rave reviews as being the best sounding streamer out there, each successive product was better the new T2 is amazing at its price point and challenges $7k streamer/dacs/

The lastest review https://hometheaterreview.com/lumin-x1-network-player-reviewed/

sums up Lumins history and even offers a comparison of the X1 vs the Total Dac, and DCS and the Aqua Formula, we actually have tested the upgraded Formula V2 with the Statement and it does sound even bettter.Summation the best sound the reviewer ever accheived was with the X1.

We sell some of the worlds best dacs, including T+A, Light Harmonic, Aqua Hif, Naim, Mytek, Bricasti, and with the X1 you have to spend $30-50k to better the X1, it is nice to see that other people are agreeing with exactly what we have been saying all along.

If you are looking for the best sound for the money, rock solid reliability, a fantastic feature set, Tidal, Qbouz, Spotify, Apple Airplay to play Youtube or Soundcloud, OTA upgrades, Roon endpoint, full Mqua, DSD and High data rate upsampling, upconversion and playability, solid build quality, built in volume control, the Lumin products are hard to beat.

Paradigm Persona the right source matters ! 

 

10-16-2019   As one of the top Paradigm Personas dealers, we have been following with some hilarity a particular poster who is going on all the Paradigm Personas threads and wiillfully lambasting the speakers in the pursuit of making his speaker choice the superior performer.

After reading his posts a few points we would like to point out: Every loudspeaker in this industry is not perfect.

Although speaker X may do certain things like much more expensive loudspeakers it all comes down to personal taste and what you value over other qualites, imaging, tonality, bass response, etc. Just because a "dealer" or rep has setup a system doesn’t mean that that is a good setup.

Many dealers don’t have the right matching gear, correctly sized sound room or experience with the product to make a great sounding setup.

PARADIGM PERSONA


Some background, our compnay was founded by me, a man with over 30 years of professional audio sales and design experience. In the trenches for 30 years you get to hear a lot of different gear and play with many combinations of prodoucts you learn a lot about system matching, your also learn a lot by working at two ot the largest and most prolific high end dealers in NYC.

Our approach is to start with the loudspeakers, then find matching electronics, and cabing and then use the choice of digital or analog components flavor the sound to create the overall result.  Our reference Persona setup is one of the best in the country, a blending of T+A electronics, Enkelin Cables, Audio Magic power conditioning, room tunning and system tunning, Critical Mass rack and footers, NCF boosters, etc.

With the right source this system has been magical and with the wrong source good but not inspiring or when thing s were really off just plain bad.

We have had a love hate relationship with Aqua Hifi, we love the overall sound, and the 100% modularity, except that the Formula XHD had a lot going for it, huge soundstage, good depth, good overall resolution but had a bit of an opaque quality to it in the upper midrange that precluded the dac from being to our ears the right match to this lofty system.

Then we heard about the new analog board that is supposed to transform the Aqua. We ordered the board which looked identical to the previous board, so we were initially concerned. Then after firing up the dac, wow that sounds different the new Formula now went from being recesssed to being much more forward, after a few days of playing the dac now sounded spectacular and digital started really giving analog a run for its money.

The point of this story is many times audiophiles throw the baby out with the bath water. sometimes, just changing your dac, transport, cables, adding power conditioning, repositioning, footers etc can totally transform a system.

We went from a really expensive system that wasn’t making magic to one that was just by chaning a board in the dac and again just by looking at the board there was no apparent differences, so many people might have been skeptical.

TRITON 1R

Golden Ear Triton 1R break in and new footers !

 

06-25 2019   We just became Golden Ear dealers after hearing them sound amazing at Axpona.

The Triton 1R seems to be an utterly amazing value, and they seem to improve right out of the box. We are going to add a full set of Isoacoustics footers on them, have other people done this?  Any ideas on how many real hours they need to break in for?

What other speakers were people auditioning before going for them?  Our initial impression is they are a zillion times better than the original Trition 1 which seemed to sound either boomy or tizzy, are people's reactions that the newer reference speakers are dramatically improved over the original products?

To our ears the new Trition 1R's seem to be magical especially for the price.
