  1. I was triamping my horns with Naim gear so I had him make me one with 6 channels of SE. Relays switch the resistors in/out so one controller can control multiple channels I have since reconfigured it with a single balanced amp so I have 2 channels of balanced using 4 of the 6. So think of it as individual pairs of volume controls. A pair can either be a stereo SE preamp or one channel of a balanced preamp. Keep adding pairs until you get as many balanced channels as you want. At $1295 a pair you are looking at $10K+ for an eight channel balanced control. Guy is a very good person to deal with so maybe a well know reviewer might get a price break ?? You can ask I assume the controller can handle as many channels as you want?
  2. Placette made me one with 6 so I assume they could do as many as you want
  3. look no further http://www.placetteaudio.com/remote_control.htm to make a balanced version I assume will be about twice as much since the bulk of the cost is the resistors used. It is what I'm using. Rossini w/clock - Placette balanced Passive - Pass XA30.8 - Avantgarde Duo Omega with bass horns. Remote control completely transparent volume control.... you could also contact Dave Slagle about a transformer based attenuator. He and Jeffrey Jackson were just featured in the March issue of Stereophile in the Salt Cellar article. http://www.intactaudio.com/ oops, EDIT forgot to mention, a key "component" in the system is Mitch Barnett's help in configuring convolution filters using Audiolense. A HUGE improvement in integrating the bass horns
  4. thanks everyone for the input and advice. So the search continues. Looks like a Roon server is the best option, not that I couldn't live without the library management even though I do really like Roon radio, but I am not going to give up the convolution filters. . The Innuos Statement looks like a candidate,, or just go old school and get the Nucleus
  5. sorry to quote myself, but I read the article about DSP and Mitch Barnett and took the plunge. Very happy with the Audiolense filters Mitch put together for me using Roon on Mac Mini. So does this mean if using the W20SE you have to abandon Roon and convolution or is there a way to add these filters with the W20SE?
  6. How are you connecting your Rossini to the W20SE? I just got a Rossini and clock and considering the Aurender. My main hesitation is I am so enamored with Roon and all Aurender supports is Airplay. Have you tried the clock and/or different clocks on your Rossini? thanks
  7. I have a Rossini and curious about using the DCS Rossini clock versus others. The Rossini clock is $7500 and produces 44.1 and 48K. An Antelope Audio OCX HD can do the same and is about $1500. For less than the difference in price you could add the 10MHz Antelope Audio 10MX Rubidium Atomic Master Clock or a Mutec 10Mhz master to the Antelope OCX, and be able to use the master for other devices if you have them. The Rossini clock will not accept a master clock like the Vivaldi clock will, but then you are into $15K for the Vivaldi clock plus the master. Has anybody tried any of this? Antelope OCX instead of Rossini clock, Rossini without an external clock. etc. Second question on the bridge so you can connect the Rossini ethernet direct to the Mac Mini. I have one and will try it, but have it seems you are now dependent on the clock in the Mini for the ethernet and might benefit from running it through a high quality switch with a TCXO clock, or through the EtherRegen.. have you tried any of that versus direct as you have it, assuming you still do it that way thanks
  8. Not having access to a local dealer my experience with DCS was instigated on faith. I first bought a used Debussy and was very impressed. Compared to the PS Audio Directstream I had or the DACs in my Trinnov Altitude 16 which are both very good, it was no contest..... for me. Bear in mind, my opinion at this point was at this level you are getting into the realm of preference over superiority, but for me the Debussy was clearly preferred. I don't have all of the flowery words of a reviewer, but it was just more there, more analog, just sounds more like the real thing. I thought I was done for a while until I came across a used Rossini with clock at a good price so I took another leap of faith. OMG. I am now clearly out of the realm of preference. The Rossini is without a doubt way above the level of the other DACs I mentioned. It does everything the Debussy did that so enamored me to it but takes it to a completely different level. Highly recommended. you can see my system on Audiogon under Herman Mac Mini running Roon, Uptone power supply/fan mod Cisco 2960 ethernet switch modified with TCXO clock and removal of switching power supply Linear 12V power supply for Mini and switch (eBay Chinese that some companies rebrand and sell for a premium) DCS Rossini with Rossini Clock Placette passive preamp balanced Pass XA30.8 power amp Avantgarde DUO Omega with 16 foot DIY bass horns Cardas Clear XLR interconnects Cards Clear Cygnus speaker cables, tri-wire
  9. Often times when I have a revelation like this it turns out I can hear it with other components, not just the one where I discovered it. So do you hear this on your Rossini now? BTW, I hear not only down into the drum, but also the echo from the floor below so I can tell how far it is off of the floor 😃
  10. As I said, never say never until you've heard it, so I'm not closing my mind to or disparaging this device. However, it seems to me the jury is out on this until somebody does some listening tests that compare this device with the others available. There are a lot of options when it comes to balanced power. Every review I read about these devices seems to go on and on about how wonderful they are. So I'm not questioning whether or not this unit improves the performance of a system. My questions is what sets this device apart from the others? As far as specifications go, that is a bit of a red herring. At the end of the day it really doesn't matter how difficult they are to achieve or past a certain point even what they are. You may be too young to remember the Julian Hirsch era at "Stereo Review" where he raved on and on in the early days of transistor amplifiers giving glowing reviews of amplifiers that obtained lower and lower and lower distortion. Turns out they sounded like crap even though they measured very well. So bravo to these guys for achieving spectacular measurements. Perhaps it is a monumental feat that they achieved 20dB rejection at 1 gigahertz or whatever the numbers are. Just not convinced it makes any real world difference. I have no doubt that Chris is hearing the stated improvements, but does this device perform better than those that cost much less? Given the challenges involved I doubt we ever see a balanced power shootout. One significant hurdle is the sheer size of these things as has been noted. Couple that with the difficulties in installing some and comparative reviews become logistically very difficult if not impossible. For instance, I read a glowing review of an Equitech 5Kv wall mount unit that weighs over 300 pounds and had to be installed by electricians as part of the electrical system versus just plugging it in. The reviewer bought it before the review so he could get it installed. Does the unit discussed here outperform the $10K Equitech unit? We'll probably never know.
  11. I firmly believe that one of the main factors that should determine the value of an audio component is how it performs, not what it cost to manufacture. It is also determined by how easily somebody else can deliver the same performance for less money. So $20,000 for what appears to be basically a balanced transformer seems excessive no matter how you value it. Knowing what I know about electronics, it is highly doubtful this guy has discovered a proprietary breakthrough in transformer technology that makes this one worth that much more than the competition, which is easily half that. Hand wound, sounds sexy but at the end of the day… who cares? I do see the value in balanced power and of course never say never until you’ve heard it, but I do not see the value in paying an extra $10K to get his
  12. their website sucks. I clicked all over the place and there is nowhere I can find that explains the different plans. Select "streaming plans" or "discover the Qobuz memberships" and it takes you to Studio Premier but really doesn't say what it is or what the other plans are. If you find the link to "explore our plans" you go to the same place. Is there only one plan now? It mentions "Sublime" but I can't find what that is. Click on "see compatible hi-fi brands" and you go to a page that talks about different resolutions.
  13. thanks to all including the folks who initially posted about this.. all is working now.. Router - TCXO switch - Mac Mini USB to Ethernet adapter -Mini running Roon - Mini ethernet to Directstream DAC I gave the DS a static IP address as suggested by somebody One of the touted features of the DS DAC is it's supposed immunity to whatever input is used since it upsamples everything to 20X DSD and processes from there. Initial impression is differences if any are very subtle. I'm to the point in this journey that I have no patience for extensive A-B comparisons. I don't have the patience to go back and forth multiple times to try and detect a difference. Since ethernet input can process MQA I'll stick with that.
  14. Thank you, I will get a USB to Ethernet and try it. My Mac Mini does not have the USB C style thunderbolt connector I see on all of the TB to Ethernet adapters I can find one minor point that threw me off, they are not " exact instructions" since you don't go direct from Network to Manage Virtual Interfaces. You have to click the little wheel in the lower left of the window. I know just enough to be dangerous so simple things like that stump me. Thanks again
  15. I've spent a few hours digging through the threads here as well as other sites and can't find an answer. I keep reading about bridging my computer to my ethernet DAC but can't find how to do it. If I understand it means my computer hooks up directly to my DAC, no switch in between. I did find a few links in threads were but they were dead. I did see a thread that has over 600 pages that says in several places "this has been covered in this thread" but can't find it. So not for lack of trying on my part, but please... how is it done? UPDATE I did find below. It talks about opening System Preferences > Network > Managing Virtual Interfaces but this is not correct. There is no option in Network for Managing Virtual Interfaces. After much search I found out you have to click the little wheel in the Network window to find it. Maybe obvious to whoever posted but not to me. So.. if I get a Thunderbolt to ethernet adapter can I bridge to it and get what I want using the instructions below? i.e. hook my Mini to my home network via the ethernet port and hook the DAC to the Thunderbolt ethernet port?
