Hi-fi: CYRUS QXR-CARD (750$) with ESS-chip (but which ?) ;-)

hi there 😉 ,

i´m proud to announce 😉 , that „Cyrus“ (former „Mission Amps“, and u know i LOVE the „Mission„-sound/speaker 😉 ) also uses an ESS-Sabre Chip (+XMOS-USB-chip)) on their „new“(2019) add-on dac-board

CYRUS QXR-CARD (750$)

  • 32-bit/768kHz audio resolution for digital files through asynchronous USB / Native DSD512
  • ((although I’m not sure of the exact chipset !!))

„..uses an ESS Sabre DAC chip, offering improvements over the previous Qx 24-bit Burr-Brown DAC, creating a wider soundstage, opening the layers of your music for perfect clarity..“ (as said and knowing: much, much better as Burr-Brown etc..!! ;-))

u can use it in the following „Cyrus“-devices->82DAC, 82DAC Qx, 8 DAC, 8 DAC Qx, 8 a, 6 DAC, 6a, 8 XP, 8 XPd, 8 XPd Qx, 6 XP, 6 XPd, Pre2DAC, Pre2DAC Qx, Pre DAC, Pre DAC Qx, Pre XP, Pre XPd, Pre XPd Qx

in addition to that the five year old „Cyrus“ One also used (at that time) an ES9018K2M as DAC-part..(pictures are from a brand new „Cyrus i9-XR„(3500$) + 82 DAC)

so, i´m only saying this to see/know, that i/we 😉 are on the right track since years… 😉

more to come, many greets 😉

Raspberry Pico is out !! 4$, 2xI2S, 2xSPI etc../ Twister OS for Pi4

hi there ;-),

found by chance that a new „Raspberry Pico !! “ is out/available..

Cost is about 4$, software is micro-phyton or C/C++, has USB1.1, Dualcore ARM cortex 133mhz, looks like an ESP32-alternative..

some more technical specs->

Mikrocontroller RP2040
• 2 MB QSPI Flash-Speicher,• 256 KB RAM,• 2x 20 I/O Pinleiste (30x GPIO-Pins 3,3V),• ADC 12-Bit 500ksps,• 2x UART / 2x I2C / 2x SPI / 16x PWM
• RTC / Timer mit 4 Alarmen,• Pinabstand: 2,54 mm
• Micro-USB 1.1 für Strom und Datenübertragung

u can get it for example here-> https://www.rasppishop.de/Raspberry-Pi-Pico-RP2040-ARM-Cortex-SBC

and here´s a tutorial how getting started->https://pico.raspberrypi.org/getting-started/

by that, i´ve „discovered“ „TWISTER-OS !!„->absolutely super great (for RPI-4s)..

https://twisteros.com/

absolutely super nice + top usable, + absolutely sleeky look, it has tons of software pre-installed (Kodi,VLC-Player,Retro Pie,Steam-client etc..) and the great advantage is still the phenomenal sound (over USB to a xmos-bridge->I2S->ES9038Q2M) because of the short electronical circuits on the board (as mentioned in the article before), absolutely great and for the first time a real good OS for the Raspberry Pi-4 !! (its based on the normal Raspberry OS)

fantastic, give it a try !! 😉

another thing is that i´ve bought now a third pair of speaker (Mission 760i (not SE)) this time and will tell u then more very interesting facts on these Mission-lines (760,780)..wanted originally make a new subsite for it (/mission-speaker) for it..

by that a very interesting site is also this: https://www.hifiengine.com/

https://www.hifishark.com/ (link also in a widget on the right) is a very good adress for „used“ hifi-gear (crawler), cause this is also a „hi-fi website“ 😉 (or is intented to be 😉 )..

more to come „in this fashion“,

greets for now !! 😉

Wharfedale Diamond 9.1 vs. Mission 760i/780 ->no comparison.. / ESP32-Cam

So, first: sorry for lately not soo much posting here .. 😉

Second, and because this is also mainly a „hi-fi“-related website i´m very glad to be able to post here also some speaker-experiences..

I´ve just bought some „Wharfedale Diamond 9.1 (white)“ to compare it with my old speakers (Mission 760i) and also to „upgrade“ my hifi-gear in general..

and because this discussion „which sounds better ->Wharfedale 9.1 oder Missions (lastet Centuries 😉 ) ?“-> i have now the answer:

Absolutely no comparison !!! The missions have a so much greater „soundstage/room/hifi-sound..“with them, really „hi-fi“ has just begun 😉 ..and because there´s always a „certain philosophie“ (sound-wise) behind the speaker-manufactories i would say the „Wharfedale“-philosophie is not mine/direction ;-). (guess i have to buy some Dali Zensor, KEFs or monitor-audios next.. )

by that i´ve bought some ESP32-Cam-Board + Cam(5,99$)->will post some experiences with it later !!

many greets from here for now !! 😉
