Tonight I brought the SR1a to another level. This may sound crazy and I need to verify my findings over several days and listening sessions, but check this out. 

 

Roon > HQPlayer > APL HiFi DSD SR MK2 DAC > Audio Research VT80SE amp > SR1a interface > SR1a

 

I'm using HQPlayer's volume control and its upsampling everything to DSD256. What I'm hearing is astounding. There are many more variables to try in this scenario, so I won't draw any conclusions just yet. I only know that what I'm hearing now is on another level. 

 

I'm surprised you are getting enough volume with the VT80, I remember seeing a few people say the 75 watts was not enough to drive it.

 

When you do finalize the settings for HQplayer, could you share all of the setting so others can test it as well?

Would anyone consider a 150watt tube amp?

 

The MingDa MC368-B150 sells on china-hifi-audio.com for $2,300 plus shipping.

This is the only KT150 tube amplifier that I found that advertises 150 watts.

 

Every other KT150 based tube amp I seen is either 100watts or under. The KT150 is, I think, the most powerful tube on the market for pure wattage.

A pair of these makes 140 watts each with EL-34s, who knows how high that will go with KT150s which they can also run

Or the integrated version...

McIntosh...

Go all the way!

I suspect you didn't look very hard and I think there is more to it than a power rating. I think finding an amp with a stout ability to drive a lot of current into the load is more important than the ultimate power rating.

 

I haven't considered mono amps, but that's a lot of equipment, cables & space to drive one single earspeaker.

 

That McIntosh is the only integrated I see rated at 150watts, but it costs $15,000.

I remember seeing a few others with even more tubes & at even higher prices, but those are't something anyone can realistically buy.
