Also - don’t know how you feel about "Stax Mafia" / Kevin Gilmore electrostatic amp designs, but you might consider snagging a KGST (cheaper), KGGG (more expensive), or BHSE (Headamp, more expensive) when they come up on the used market. Just avoid any Chinese builds and stick to known builders.
Even the T-8000 is reportedly significantly underpowered compared to the Gilmore designs. I admittedly listen pretty loud, and have heard the Stax 727 absolutely fall apart, to mush, as I raised volume. You won’t get good dynamics and solid imaging if it’s going that way, and a more powerful amp would have a much bigger impact than adding the preamp in that case. The Mafia’s all-solid-state deigns (KGSShv, Carbon) can be a bit on the leaner and brighter side, which I definitely don’t prefer, but their tube hybrid designs really pull it together for my tastes.
In particular I find the KGST a nice pairing with L700 and 009 without breaking the bank.
- KGST - Kevin Gilmore Single Triode, using 6S4A tubes. It's the simplest amp in this lineup.
- KGGG - Kevin Gilmore Grounded Grid (EL34 driven with grounded grid)
- KGSShv - Kevin Gilmore Solid State, High Voltage version
- Carbon - Modified & improved KGSShv with Silicon Carbide FET output transistors
- BHSE - Blue Hawaii was Kevin’s first attempt to replicate Stax’s legendary T2 amplifier before he had access to its circuit diagram. Her scribbled out this design on a cocktail napkin while drinking Blue Hawaii’s on vacation lol. The "SE" indicates Headamp’s (Justin Wilson) improved and modified version.
