Jeff Rowlands Amp and Dac vs. VAC amp and DAC

Any other suggestions?

I have all Jeff Rowland components(625 S2, Corus preamp, Aeris DAC) driving Monitor Audio PL500s. Despite what anyone says, there aren’t any absolutes in Audio; let your own ears decide.

I had the Continuum S2 integrated amp and now the 625 S2. I submit the 625 S2 is a decent step-up from the Continuum S2 that should be easily heard, but relatively expensive. You can use the Aeris DAC to drive the 625 or use a preamp.

I have heard the vac integrated at length and it is a great amp. I also prefer tubes over ss for the Wilsons

I hope you will indulge me a bit here. I have heard the VAC Sigma 160iSE and the JR 625 upgrade both with the Aeris as the DAC. I am a bit nervous about tubes. This would be my first time with a tube amp. I do agree that the VAC is amazing. The JR is also good and it is a bit easier given it is plug and play and no tweaking, changing tubes, etc. is required -- so are tubes really difficult? Is the sound worth it? I agree that the VAC is fabulous but the JR is also very nice. Please say more on the topic if you can? 

Keep discussing guys- I have always wanted to demo both VAC & JR gear.
