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 ... 
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 ... 
Jeff Rowland Corus versus Audio Research Ref 6
Hi Richard, have you considered adding a Rowland supercap-based PSU (Power Storage Unit) external supercap-based power supply to power your Corus.... As you Know, I have used PSU on my Rowland Aeris DAC for a couple of years and it has raised the ... 
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... 
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... 
Class D Technology
I cannot hear any trace of harmonic distortions on the 3rd or any other partials when I play music with my class D Rowland M925 monos or class D Rowland Daemon integrated.... Nor do they intermodulate. They are as sweet and stunning as can be.As f... 
Jeff Rowland Daemon – Reviewing The JRDG Superintegrated Flagship Amplifier
Hello @lwilkins44, your question is very interesting and somewhat complex because of the relatively large number of variables involved. A reasonable treatment bears a dedicated discussion, which would exceed the scope of this thread.   Some of the... 
Why Don't More People Into Music Reproduction At Home Play Around With Musical Instruments
All, not all categories of musical instruments require capital investments comparable to high end audio equipment.   European made 1st tier professional level High brass horns can be had for well under $4K. See for example the rather spectacular A... 
Jeff Rowland Daemon – Reviewing The JRDG Superintegrated Flagship Amplifier
Hello A1UC, it was indeed fab chatting with you about Rowland Daemon!   I have since checked with the Rowland factory. I was told that Albert at Precision AV in Chicago should have the amazing Daemon in stock for you by mid or late next week.   No... 
Jeff Rowland Daemon – Reviewing The JRDG Superintegrated Flagship Amplifier
Hello Juan, happy to see you on my little watering-hole :) ... You are right, it has been a spell since I posted an update to my Daemon project. A number of stressers of a global and a personal nature -- totally unrelated to the world of audio -- ... 
Class D is just Dandy!
Hello listening99, what power rating would be ideal for your speakers? ... And what is your budget for an amp?Regards, Guido listening99 
Break in time that extends to months or maybe even years!!
Hello @DaveyF, I confess that I have not always purchased a component based on personal experience...   In the late 1970s, I purchased a Sony "high-end" cassette player solely based on looks, pedigreed reviews, specs, and frequency response graphs... 
Break in time that extends to months or maybe even years!!
Hello @limomangus, nothing has changed since the old golden days... If you are nirvanized by factory-fresh equipment, or after a couple of hours of burn in, or 50, 100, 250, or whatever hours of break-in, continue to be happy about your audiophili...
