Yoram Diamand Posted May 13, 2020 Share Posted May 13, 2020 Hi, I use a QB-9 24/96 with Qobuz Studio, and I am saving my pennies for the DSD Twenty upgrade. Some of you talk about the Regen USB tool, I myself have the iFi Audio nano iUSB3.0 Power Supply & Data Optimizer, which you cannot buy anymore. Is it a good idea to use it with the upgrade, or better to trust the clocking etc. of the DSD Twenty technology? Of course I can have a listen when the gear is there, but what would be the theory? I am happy with Ayre making my purchase of the QB-9 24/96 more relevant to modern times. The 24/96 I presume is now rather archaic. Link to comment
Yoram Diamand Posted May 14, 2020 Share Posted May 14, 2020 Thank you, I am betting with my 1790 euro you are right, and the DSD twenty upgrade will be a delight for my ears, coming from the 24/96. It was the inner fidelity You Tube video on Stax SR-009 amplification, that provoked the purchase, of my Ayre QB-9 Dac. My income is too modest for the SR-009, I use the L700 Mk1. It is good enough to hear a lot. Kind regards Yoram https://www.youtube.com/watch?v=0UGtjJYVew4&t=437s Ryan Berry 1 Link to comment
Yoram Diamand Posted November 27, 2020 Share Posted November 27, 2020 Hi, the QB-9 is not a digital hub, so there is no USB transport with an app on a tablet etc. Transports are costly, Lumin and Auralic ask 2000 euro, and they are not completely USB focused. I paid 1790 euro for the twenty upgrade, it will be the upgrade from the original 24/96. It is being built this week and it will be nice surely and I will be happy. There is the USB bridge a DIY computer, but I do not build computers, I don't. Pro-ject pimped this DIY computer into the Pro-ject Stream Box S2 Ultra. I listen to Qobuz studio 24/192 records too so I will need the Ayre USB driver. This transport will be a budget solution like the QB-9 24/96 was. The twenty upgrade is also in a way somewhat affordable. Lumin will be better than Pro-ject, but I spent enough. Can I use the Pro-ject with the Ayre USB driver for 24/192 Qobuz? Thank you, best wishes Yoram Link to comment

Yoram Diamand Posted December 17, 2020 Share Posted December 17, 2020 The purifier is no good, you cannot compare it to the iUSB3.0 but I saw it is not for sale new at the moment, so perhaps second hand at hifishark? Link to comment
Yoram Diamand Posted December 17, 2020 Share Posted December 17, 2020 Today I tested the Nano iFi against no decrapifier and the Twenty sounded much better without any decrapifier. Perhaps the best upgrade would be a USB transport like Pro-Ject Stream Box S2 Ultra or Lumin U1 mini. But the Twenty plain with a PC even though there is some noise or USB crap is much better than with iFi. Link to comment
Yoram Diamand Posted December 21, 2020 Share Posted December 21, 2020 Hi, as I understood, the Purifier was meant for Dacs till 500 dollar, the micro should be better, but iFi said in a forum, a Lumin U1 mini with Sbooster would be the more highend solution. $$$ Link to comment
Yoram Diamand Posted July 7, 2021 Share Posted July 7, 2021 Hi I have the RCA to my Feliks Audio Euforia headphone amp, but the XLR is still free. I was thinking of this converter: Jensen Transformers PC-2XR XLR/RCA Audio Converter Balanced to Unbalanced. Are there technical reasons why that would not work? Ideal would be to have 2 RCA outputs, one for my head amp and one for my preamp ->loudspeakers. Also: Can I use 2 outputs RCA and XLR at the same time? Thanks Yoram Link to comment
Yoram Diamand Posted March 21, 2023 Share Posted March 21, 2023 I had my computer as a source combined with an iFi regenerator, but iFi made it worse, so I bought a SOtM sMS-200 Neo-SE USB Bridge, so the source signal would not be dirty to start with and that was a very good move. I am saving for the SOtM sMS-200ultra Neo -SE. Link to comment
Yoram Diamand Posted March 21, 2023 Share Posted March 21, 2023 Mine is the new neo, and SE, Siver wire and hifi caps and SBooster power, I do not complain Link to comment
Yoram Diamand Posted May 27, 2023 Share Posted May 27, 2023 Hi, You forum people use oversampling and upsampling as if they are synonymous. I know oversampling from NOS dacs Non oversampling dacs. And Upsampling from the Chord M-scaler and external upsampling software. I did not know you could have Roon upsampling. I have no Roon, because I thought you pay 10 euro each month for basically nothing. I always thought: Upsampling is for other dacs than my QB-9 Twenty. I do not use a noisy computer anymore to feed the QB-9, I use a SOtM sMS-200 Neo- SE with silver wire, upgraded caps and a SBooster PSU. My hifi is growing into quite nice and I thought of upgrading my USB bridge towards a SOtM sMS-200ultra Neo-SE with silver wire, that one costs 1600 euro. Would anyone know a better alternative? If so please let me know😊. Thanks, Yoram Link to comment

I've been happily running a USB cable from my Roon core machine (formerly a sonicTranporter, now a Roon Nucleus) directly to the QB-9/20, but see a used JCAT for sale from a private party for a reasonable price and feel like experimenting. I've heard that there are a few DACs that don't play nice (or even play at all) with these devices, some Hegel DACs for example. Any insight or informed speculation re JCAT/QB-9 compatibility would be appreciated. jonathan I had the iFi nano USB regenerator or what it is called, but the sound it was much better without the iFi. Since then, I have a dedicated USB bridge/ streaming transport. Thus I have no noise from a noisy PC. That did help me. I donot know if it would help you. Link to comment
Yoram Diamand Posted January 14 Share Posted January 14 Hi I had a MIT silver plated USB cable and it was a very nice cable but 3 meter.Too long. Now i use a 2x 14 core Lavricables thus 28 core silver USB cable 0,5 meter. Not Audio Quest diamond still silver. I have no complaints WEN HONG 1 Link to comment
