Preamp for R2R DACs

Nicely done!  Sounds like a huge upgrade.  You might check out Audio Envy NV-SP6 cables.  They offer 30’ length at only around $250 and have built a good following here. 

@soix being an old post - thought I should share how the office set up paned out. Ended up selling OPPO 105 and the KRK Rokit (possibly the 2 weakest links). Current set up for office (15x8) room. 

HP dedicated laptop running Roon Core 
Metrum Onyx DAC 
Croft Integrated amplifier 
Harbeth P3esr speakers 

Still to add: Kimber Kable TC8 speaker cable or another less expense brand (need 30 feet of wire)
Power conditioner 
Upgrade to better IC - currently using Morrow Audio MA2

Couldn't be happier with the revamp. Sounds amazing. 

it’s only that I am afraid of potentially introducing a weak link - preamp in this case - as I am sure it’s opening a can of worms as to which preamp is better etc.

I wouldn’t worry so much about the Schiit preamp as between it and the R2R DAC it’s your speakers that would likely be the weakest link at that point. Add an Aegir amp with a pair of Silverline Minuet Supreme Plus speakers and you’re in a whole new league IMHO. And you’re right — you’re opening a can of worms here.

On the cheap, Schiit sys is a passive  pre. 2 inputs 50.00. 15 day trial.  Luminous audio has stepped alternator for 195.00.

Schiit Vali2. Tubed headphone amp/ pre amp.

Thanks for the reply. That makes sense - it’s only that I am afraid of potentially introducing a weak link - preamp in this case - as I am sure it’s opening a can of worms as to which preamp is better etc. 

Just get the smallest Schitt preamp, it costs around $400, and it will provide the volume control you need.
