Jeff Rowlands Amp and Dac vs. VAC amp and DAC

Not really puzzling. A little chaotic but it's controlled chaos.
Women are not men. Let us pray for that in Old Persian.

Jon - what's so puzzling?
rinpoche indicated earlier  that she purchased the amps and that they were dealer demos.
What difference does it make how she got the dac and speakers - she's had them and said she likes them
She already said that she wasn't in a position to rearrange her room; a lot of us have to live with constraints on maximizing listening experience 
She said that she had been offered a cable to trade the Devialet for , apparently it works   
Throughout the thread rinpoche has said she was considering a preamp  but was looking for opinions on whether to stay with DAC or insert one. She  indicated she probably wait a year on the preamp. People are entitled to change their minds if they think they see value, does she need someone else's permission?

Time for you to stay quiet, facten.

Let's not make this a gender issue, when it is all about preamps. Also, my purchases have been very clear and so have my goals. Not that I need approval here. I need(ed) suggestions and recommendations. Many of which have been very good and I have taken to heart. 

The preamp has always been part of the vision for the overall system. That is not the issue. I have listened to the system (as I wrote) and, to my ears, it sounds complete with a preamp.

Where the individual parts come from is also not an issue that you 'all need to be concerned with, but just so you have it straight the speakers, DAC, and amp are broken in (just not all by me). 

The Devialet has nothing to do with this. Nor does the USB? And yes, HD files on itunes — So, let's move on and maintain the kindness and civility we have maintained for 10 pages. I was just running by an ad for a preamp I noticed. All the best, R

Hi Rinpoche,

What you would want would be a "line stage" preamp.  The Lamm LP2.1 is a "phono stage" preamp, which as Inna indicated would be used in conjunction with a turntable, and would require a separate line stage preamp.

Note that as in the case of most phono stages the LP2.1 does not provide a volume control.  Also, a phono stage would be severely overloaded by the output of a DAC, which is at a much higher voltage level than the output of a phono cartridge.  And it would apply frequency response equalization that is only appropriate for the output of a phono cartridge.

Finally, you would want to choose a preamp providing balanced inputs and outputs, on XLR connectors, as well as unbalanced inputs and outputs on RCA connectors.

Best regards,
