System details:
Dedicated 15 amp circuit
I sometimes use a GoalZero Yeti 1250 lead acid battery generator to quiet the noise floor for critical listening fun.
Digital - old HP laptop streaming through an MHDT Orchid DAC, either via a Shunyata Venom USB or an MHDT stock red cable (they no longer apparently provide these to their customers). Tube used in the Orchid is an Amperex Bugle Boy 6DJ8 via one of those 5670 to 6DJ8 adapters. I use this setup to stream music a LOT. When I listen to this I never think "I need more detail" or "this is not resolving enough". I think "what a great tune" or "what wonderful tone".
For CD - Cambridge Audio CXC transport, connected via Nordost Blue Heaven cable.
Analog -
Garrard 401 in custom Baltic birch ply plinth. Jelco 750L tonearm, Shelter 901 MC cartridge (wonderful thing) direct into tube preamp LCR phono stage (see below). I sometimes use a Dynavector Karat 17D3 MC phono cartridge. I've used Karat cartridges for many years and always liked them.
Sony 2251 direct drive turntable with stock Sony arm hosting a Signet 3ea MM cartridge into Plinius Jarrah phono stage (solid state). Sometimes I swap in a Stanton 681 phono cartridge.
Late 1980s LP12 w/Ittok currently in storage pending rebuild of Valhalla power supply. I wonder, should I get the Valhalla rebuilt or replace it with a Mober power supply? A Mober bearing? A Karousel? It's just money, money, money...
Preamp - (the heart of my system, and I'm delighted with it) Supratek Cortese with LCR phono stage. Running vintage 6SN7 tubes and currently Philips 6922 (JAN) tubes w/ Philips SQ in the 180F position
Power amps - Quad 909 driving rebuilt Quad 2805s
Audio Electronic Supply (AES) SE1 300b power amp driving JBL 4430 studio monitors (93dB efficient).
Listening bias - I'm a writer. I mostly listen below, say, 70dB. Sometimes I crank it and the JBLs are the go-to beasts for that. 8 watts drives them very very well.
I need my system to sound detailed, rich, smooth and beautiful. IMHO neither the Supratek nor the SE1 300b amp introduce "tubey goodness" into the sound I'm hearing. Of course, I'm used to whatever it is I'm hearing. I just think my system sounds like music. Extremely livable. I love the MHDT Orchid DAC. After hearing mine several friends have bought them. Of course, I don't think that means anything at all.
We audiophiles tend to be malcontents, always seeking something better, that next little bit of something, whatever it is. I know I'm as guilty of this as the next person.
My view is that the most important element in enjoying a system - any system - is contentment. That's my rule of thumb in answer to the question "how good does a system have to be?" Only good enough that you stop thinking about/getting distracted by the idea that something needs to be better.
