Amp problem
Regarding the Pop sound when amp is turned on, there is a power on/power off sequence which must be followed. Powering up...Preamp ON, Amp ON.Powering off...Amp OFF, Preamp OFF.If you're having hum using the RCA unbalanced IC and not the balanced,... 
Hi-Fi amp recommendation
+1 for a used well regarded amp. Only buy from a seller with good feedback.

The EQ is a good temporary fix. Please keep an eye on the preamp for any shorting out or shutting down due to the tube.:-)

So, there's no tube problem in the preamp?

Chip, this has all been previously covered. Scan thru the comments.

Very well stated, @newbee

You are asking about clarity and soundstaging. My first question is, are you using room treatments? You may benefit from a DAC, but your room is a major factor in obtaining focus, imaging, and soundstage.

Also speakers are rated at 8ohms though As I stated before, KEF may rate the speaker as a 8 ohm nominal load, but you look at the impedance curve to determine which tap to use (to start with).  The frequencies in the bass and mid-bass range are at... 
Regarding prev discussion "Does your CD player not play all the way to the end of the cd?
OK, I get it now. I think what you need to look for is not a standalone transport, but you need to research who uses the best transport mechanism in their unit. That is the tray and slide mechanism.Most manufacturers have used Philips or Sony tran...

@alphaguy65The Op is using balanced cables from preamp to amp. Maybe he should try RCA unbalanced.I've also listened to the R900's with only 30W; very large cabinets with deep bass, huge soundstage.@kentrent  Something we haven't discussed is your...

Btw, one tube wouldn't cause such a serious problem. It would be the pair or could be tubes in the amp. 
Audio Research VT100 MK1 and LS15 HELP!!!
Hopefully it helps. But, there may be more than one bad tube. I hope I'm wrong.A reminder...Use the 4 ohm taps, re-seat all the tubes in the amp. Make sure they sit tight in the sockets.

V1, V2 are a pair. V3, V4 are also a left, right pair. 
Audio Research VT100 MK1 and LS15 HELP!!!
They are left and right channel. Replace both since you don't know their age.Then, hopefully the tube will not blow.

For all we know, all the preamp tubes could be weak. But start by changing the 3 and 4 tubes.
