Jeff Rowland Daemon – Reviewing The JRDG Superintegrated Flagship Amplifier
All, I realize that a very significant time has elapsed since my last Daemon update. Today, I would like to share with you my experiences using Daemon as a DAC+line-stage front end to the M925 monoblock amplifiers.   Just for starters, in case ...

Not assuming anything.... I have no idea what speakers you might have installed.... I purely report what I heard through my USB Plantronic headsets connected to HP Spectre.I can only hope that things will eventually improve.G.

Hi Jay, worth pointing out that GTT Audio is unique, in that it is both a distributor as well as a dealer/retailer for the brands that the company represents.Regards, G. 
No-one talks about Rowlands anymore
Actually, Rowland produces a mix of class A/B and class D power amplifiers. Its monoblock M735 flagship, as well as the M625 S2 stereo amp, both run in class A/B. See for example the M735 page at:https://www.jeffrowlandgroup.com/model-735/The only... 
Jeff Rowland Corus versus Audio Research Ref 6
I agree with you completely Richard.... Adding an $8K component to a system sight unseen (or should I say hearing unheard) is inherently an anxiety-generating proposition. Good news is that Galen Carol in your San Antonio should easily be able to ...

I vote for the Vivid G1. No, I do not own them, but a good friend of mine will soon be powering them with a pair of class A/B Rowland M735 monoblocks.G.  
Transformer coupled outputs/inputs in preamplifiers.
Well implemented transformer coupling not only increases cross-component compatibility, but also significantly reduces common-mode noise and intermodulative artifacts... Case in point, for a couple decades, Jeff Rowland has been using Lundahl inpu...

For more/less opposite reasons to each other, I have voted thumb's down for both presentations 1 and 2.G.

The first set sounds ripe and bloated... The second set sounds sterile and harmonically limited... Not sure which one has footers, and which one does not.G.

Class D Technology
I should however like to point out that as with any other class of operation and topologies, class D amps range from the marvellous to the horrid. When I visited RMAF a few years ago, there was an equal proportion of class D amps and tube, class A...
