AbeCollins's The Main System in the Basement System
IP Address: Last Update: September 22, 2021 at 21:37:42
Amplifier: The current August 2021 basement setup as pictured and described below:

- PS Audio GainCell DAC / Analog Preamp.
- PS Audio NuWave DSD DAC.
- PS Audio M700 monoblocks 350-WPC at 8-Ohms
- Mac Mini 2012 Intel i7 Quad-Core 2.6GHz running Roon.
- iPad running Roon Remote.
- 12 VDC 10 Amp Linear Power Supply for Mac Mini.
- Wirless keyboard, mouse, or portable iPad for remote control.
- Sonore microRendu network streamer hidden behind rack.
- DIY Raspberry Pi network streamer behind the rack.
- Synology NAS running Roon Core hidden in utility room.
- Hardwired CAT6 Ethernet throughout house.
- KAB Technics SL-1200mkII turntable.
- Dynavector DV-20XH Cartridge.
- PS Audio GCPH Phono preamp.
- Thiel CS2.4 speakers.
- Dedicated AC power to the audio gear.

I run Roon Core on the Synology NAS hidden away in the utility room with my music library on the NAS. I have Roon on the Mac Mini acting as a network streamer connected to the PS Audio NuWave DSD DAC. Additionally, the microRendu streamer (hidden behind the rack) drives the GainCell DAC / Preamp. Everything is on CAT6 1-Gigabit Ethernet. I control it all using the Mac Mini on the big screen TV -or- with the iPad running Roon Remote. In addition to my ripped CD files and hi-res downloads on the NAS, I also control the Tidal and Qobuz streaming services from the Mac Mini or iPad remote with Roon at the center of it all.

Other items I place in the setup when I feel like mixing it up:
- Rogue Cronus Magnum 100wpc Integrated Amp with KT120 power tubes.
- A couple DIY Raspberry Pi based streamers running DietPi & Roon Bridge.
- Tannoy Definition D500 tower speakers.

Samsung 75-inch Q90T QLED TV

August 7, 2021

TV: Sonos ARC Soundbar, Sonos SL rear speakers, Sonos Sub. The Sonos system is completely independent of the main 2-ch setup.

Note: The TV picture above shows 2020 but the Olympics in Tokyo actually took place in the summer of 2021.

Mac Mini. microRendu network streamer. PS Audio GainCell DAC/Preamp. PS Audio NuWave DSD DAC. PS Audio M700 monoblocks.

Sony Blu-Ray player. KAB Technics SL-1200mkII TT. Marshall 80-Watt RMS Bluetooth speaker & J-38 telegraph key just for grins.

Synology NAS tucked away in the basemewnt utility room. My music is stored on the smaller DS-718+. Household computer backups go to the DS-918+ NAS on a nightly basis. The CyberPower UPS keep the NAS going through any brief power outages.

A few Roon Remote screen shots on the portable iPad. Music does not reside on the iPad. It is just a Remote Control into Roon.

The iPad is used to remotely control music that reside on my Synology NAS or from the Qobuz and Tidal streaming services.

Roon showing the source music file as a 'hi-res' 24-bit / 192-KHz uncompressed AIFF. It sounds great too!

Music Preferences and Comments:
Music Used (Genre/Selections): - Rock, classic rock, punk, alternative, blues, pop
- Jazz, some country / cross-over
- Americana / Folk / 60's Protest Music
System Goals/Comments: .
System Strengths: - Powerful, robust and dynamic yet delicate when called for by the music. Excellent transparency, imaging, and frequency extension. Nice bass slam, depth and speed made me change my mind about a sub. There is a sub but it is part of the Sonos surround system strictly for the TV.

- Very flexible setup with a variety of options not only for audio but YouTube, Netflix, HBO Max, Disney+, AppleTV, Amazon Prime Video, CableTV, Over-the-Air TV with HDTV antenna outside, and general purpose web browsing to the big screen. However, the TV does not need to be ON if all I want is music in which case I navigate and control playback with the iPad as a remote control for Roon.
System Weaknesses: - The Thiel speakers limit my choices in power amps as the Thiels really do require a good amount of clean power to drive them to their full potential. I've tried amps in the 100-Watt range and some do OK but not great. For anything in the 100-Watt or less range my Tannoy speakers do much better. However, the Thiel speakers driven properly sound better overall.
Video/HT System: None
