Should I got full tubes or stick with hybrid amps?

Tubes Harsh? Huh?

I’ve used Tubes since 1973, 47 years, harshness never entered my ears.

always in the 30-35-45 wpc size (4 power tubes total)

Fisher Mono Blocks 80Z (EL37, substitutes)
Fisher Receiver 500C; 800C (7591, substitutes)
Current Cayin A88T 6550 or KT88

I think I put EL34’s in the Fisher Mono’s, -5 wpc, a vauge memory

Fisher’s used lots of 12...
Cayin uses 6....
Other Cayin’s now use 12 ....

I found both the pre 6’s and the Power tubes brands definitely sounded dirrerent/preferrable, but none sounded harsh.

I’m thinking I like the 6.... better than the 12 ....

You seem to be forgetting that those big output tubes have smaller tubes driving them. Those smaller tubes CAN sound harsh and pass that harshness on to the output tubes. I find that it is mostly the new production tubes that can impart harshness, but some NOS can also have those characteristics. If those tubes didn’t affect the tone, nobody would bother rolling them to find the best sound. It should also be noted that tubes for the most part are a lot more finicky when it comes to the speakers they sound best with.

Didn't think about the fireplace or the pics.  Definitely need to look at some acoustic panels.

Great suggestions.  I only listen from my desk (in this room).The black chair just sits there. Considering getting rid of it.  I don't use it. Equipment is to the left of my desk. Sitting on a table.  Thanks for the tip about 4 power tubes.  That will probably change what I can look at.

I'll take a look at the Vincent.  I heard (somewhere) that they soldered their tubes and weren't very helpful if you wanted to change them or needed other support.  Was your experience with them different?  

EDIT: The Vincent is almost $3k.....  dang.  I like everything else about it though! Tone controls and loudness are sweet. 

@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 ! :-)
