  1. I bought a Lumin instead, the firmware and software is established for quite some time with very few bugs. The bridge had engineered MQA before a USB out, kind of an odd decision. Anyway, best of luck for the hunt.
  2. I know where you’re coming from, TV bites and no music is not the greatest. I have two Bluetooth battery speakers, JBL Flip 4 and the KEF Muo. The JBL was bought cause I forgot to bring the KEF. Weight is an issue, the KEF is close to 1kg, it has the better bass though and runs for hours on end. Both can accept a 3.5mm connector direct to a computer or phone audio to take advantage of the computer’s sound card. For some silly reason, the HP envy sound card doesn’t playback red book or it’s multiples, strange. To keep the speaker undamaged for many rough baggage handling, strongly recommend to retain the original carton and fillers, this has worked now for three years without incident.
  3. Cindy Bradley is one hellova Trumpet Smooth Jazz master ! For Smooth Jazz, trumpet sounds better to me than sax, classier, wider range of emotions. Anyway a few albums to explore, recommended. Technically DR is not that great around the 4-5's... resolution and sound stage are very good indeed. Hard to choose which is best, can't really go wrong, production values are classy to match.
  4. Remember the 12 inch singles? First time I remember them was with DISCO, yes, they were used to pump bass par excellence, the 12 inch singles were an advantage with larger spaced grooves but shorter playing time, which was not a matter for single purposes. DJ Ben Liebrand has devoted countless hours in collating 12in vinyl for digital, collated in a collection of Grand 12 Inches. There's so far 16 volumes each with sometimes 4CDs per album. his notes: " Ben Liebrand : "These are the roots of my career in music". These tracks have determined the path to follow and many of them where revolutionary and truly progressive at the time they where originally released. I have taken the greatest care to come up with the best possible masters, sometimes comparing up to 5 different versions to find out which one sounded the best and most pure. And sometimes even baking the analog master tapes to make them playable again. The heat evaporates the moisture in the coating of the tape. The otherwise moist backing will clog up all parts of the tape recorder the tape touches, leaving a dark glue like substance grinding everything to a halt. After the backing process, the tape becomes playable again and the transfer to digital is performed. Some tracks feature a combination of vocal and dub version just as I used to perform that combination in a live DJ-set. Such a combination features the best parts from the vocal and dub version, capturing the complete feel of what that track meant to me. Enjoy! Ben Liebrand" As for mastering, well, take a look at Blondie's 'Rapture', selected at random, runs for 10 minutes. Where's the compression???? Nowhere, this is a very clean recording, DR12 (as reported by Jriver). This track is typical, all the peaks are naturally where they are supposed to be with air around them. Just brilliant. The content is very 70's Disco and variants. From the main page on the website, how 12in vinyl was converted to digital: "Transferring from Vinyl Only when no master can be found at all (including having contacted the original artists in many occasions) I have to revert to Vinyl, and only do so if a mint copy is at hand. So.... Man am I happy I always spun my records using the Stanton 681 EEE's, instead of abusing them with the surface grating 500AL's. So... Transfer was done using a Denon 304 Moving coil cartridge, amplified by a Studer Phone Pre-amp to +4dB balanced line signal. The signal was then fed into the AD converters of a Tascam DA30 and recorded directly to 44.1 kHz 16 bit. Yes, A higher bit rate is better, but only if it stays at that bit rate. Down-sampling to the CD standard introduces more unwanted side effects than simply recording it at the correct sample and bit rate in the first place. All clicks where removed by hand. instead of editing them out , which removes short spaces of time, they were removed by means of interpolation, thus keeping the correct timing. Fade-out's were cleaned up, intros where inspected at sample-zoomed view. Distorted section were repaired by interchanging from identical snippets elsewhere in the song and all was done to ensure that you have the best possible audio experience in lack of the preferred analog tape master." For the Disco lover and bass addict, this is the mother-load There are also upgrades as WAVs for some volumes, the Discogs page reveals.
  5. Sorry, not my experience. In an ambient of 30C (+), the drives soon fail.
  6. Like most plastic coated portable drives, their use for 24/7 application is highly doubtful. Whether WD, Seagate or metal clad cases, doesn't matter, they heat up and cause the drives or their controllers to fail in only a few months. What works for me (so far) to backup the internal Server drive's Music folder, the Seagate 8TB drive is powered up remotely (Kasa smart switch) when needed, connected directly to the server via USB 3. Once the backup is finished, the disk is ejected and powered off. The drive would only be on for 10 minutes at the most. Backup software is Beyond Compare.
  7. I wonder if the correct card is recognized. There is the method in device manager in the hardware id which can be googled to find the correct variant that the device reports to windows.
  8. Here's an article from the National Broadcaster regarding the use of plastics for recorded music, particularly with the advent of streaming. "....emissions from plastic music products stayed steady over the decades, between 140 and 160 million kilograms a year in the United States. But in 2016, with streaming dominant, the output was about 200 million kilograms." Now, I leave my music server storage and media server on all the time and reading the above, has made me rethink on the energy use. Audio equipment is turned off when not in use, so the Servers should be as well. A NAS is not the solution either, the media server draws far less power when measured and network file handling on a NAS from old ones anyway is slow to start and most likely full of noise.
  9. Where, when did you receive the Accuphase cables? The 40th anniversary models.
  10. It's a little late to detail some responses, but don't float the output of the Topaz. Ground X4, it keeps the ground to neutral voltage at 0V.
  11. This one, they work, I have two of them for each radio, installed since, woah, 2006. Cured ground loop hum.
  12. Agreed about the push in on the outlets. However Push in technology when applied correctly works very well as described in this Phoenix video.
  13. Just a word of definition needed as a guide for your posts on isolation. A Topaz Ultra isolator (transformer) tries really hard to block leakage currents. The lower the pf between the windings, the greater the impedance for these frequencies, but it is not a true isolation device as far as noise is concerned. True isolation is a light fibre for example, but not going to work for mains power. What the Topaz will do, is to stop nasty voltage transients and severely cripple common mode noise from entering the clean area. You're on the right track with the HDMI fibre cables and isolating signals from equipment with that method or similar. All AC devices should be plugged into the one Topaz/power strip at the one place. Once there are other transformers for individual equipment, such as sources and power amps for example are on the network, the grounds tend to lift reference from one equipment to the other. Once that happens, you end up with an uncontrollable noise generator as the reference has shifted to another spot. Don't forget Jensen isolators on the Cable/FM/TV antenna infeed.
  14. There's plating and plating of metals. Covering of metals to protect them from corrosion need to be applied correctly at the manufacturing stage, which often are not.
  15. You may have forgotten about the unwanted harmonics on the AC network that work against speaker voice coils, eg the 5th. Raif Smith measured harmonics on the input to speakers which bypassed the amp power supply. Clean up harmonics either the hard way by measurement and make a lossy filter or use a transformer with a tight balanced secondary and the bass is restored.
