Should I got full tubes or stick with hybrid amps?

@soundchasr, I’d place two nice dog beds in the middle. Good absorption, especially when occupied. 

I am actually doing an all Tube System for the first time in my life. I've had Class A/B Transistor Amps (Adcom/McIntosh) and Class D (PS Audio). I've enjoyed them all but once I got into Electrostatic Headphones by way of  a Stax SRM-007tA (eBay) with a pair of Koss ESP-95X's (Massdrop), I am now hooked. This past summer, I traded in all my PS Audio Amps for a Balanced Audio Technology VK50-SE Preamplifier. My friend was selling his VTL 300MB's at the time but it was well out of my budget. The Music Room was a great place to work with with the PS Audio trade for BAT Preamp. I'm now working on getting a Jolida Fusion 3502P Amplifier to power the top section of my KEF 105/3's.  The Woofers of those Speakers are being driven by a 1000W ICE Power Amplifier from Parts Express. 

Enjoy the ride ! :-)

Ok, everyone.  Let's say I put aside $2,000 for an integrated or separates.  What say you!?

I have never heard a hybrid that wasn’t the worst of both. I am picky, as I had a wonderful CJ tube preamp for decades, but the only tube piece I’d consider under $5k is the Rogue Audio Cronus Magnum III. Separated only make sense if your budget is well over $10k

Those speakers 88 sensitivity put you in the category of more power needed, I think you might need more money in your budget. 

Spread the difference over several years, then it seems easier.
