Tube Amp for Coda 8 Part 2

The answer is, ‘it depends’. I could not find too much on the implementation of the M1 digital volume control, but typically there is some risk of signal loss especially at lower volumes. Given the quality of your gear, it may take a bit of coin to find the answer and determine if it is worth it.
 

My previous amp was a Coda #8 and I tried at least five different preamps with it, each one was different. If you are even thinking of it, I would recommend you try one and see for yourself. It is part of the fun. Be aware that the right cables will make a big difference as you add component to the chain.

@zlone Good point on the cables.  Vacuum tubes also make a big difference in a preamp like mine.  Put the wrong tubes in it and the performance is nowhere near its' potential. 

I kinda went through this same situation last fall. But with different equipment. I sold my pre amp and amp and got a new Coda 5.5s. At that time I had a Denafrips Venus II DAC I bought new in 2021. That DAC fed my Legacy Audio Wavelet II which I then used as a preamp for volume control. The Wavelet also works as an outboard crossover/DSP room correction unit sending the mid/top to the Coda and the bass to the internal amps in my Legacy Audio Focus XD’s. I was considering getting a nice Tube pre amp such as the Aric Audio Motherload II or the new Spatial Audio Raven. I researched as much as I could to find at what level the Wavelet acts as a quality Pre amp and weather a pre amp prior to it would make a noticeable difference.  I was so close to getting the Raven but a conversation with a dealer convinced me to not do that with only 1 input needed (from the DAC) and add more stuff in the chain, another high cost interconnect and power cord. He convinced me to keep it simple and for go all that. So, I decided to instead get a better DAC and ended up with the new Denafrips Terminator 15th. I am happy with the sound I get. But I too still struggle with the curiosity if injecting a pre amp into the chain will make a significant difference too. It would be a very expensive experiment so I can’t really try it. Legacy presents all it products at shows using just the Wavelet even in their $80,000 top speaker system with good results so it can’t be too bad. So that’s my logic. Your DAC is very good and keeping the chain simple may bear quite good results but you have to satisfy yourself. Good luck on your journey.

@fthompson251 - eloquently said and thank you for that!                                  After a TON of research, I may just stick with my digital attenuated DAC for my pre-amp.

If you do not listen at very low volume, then the digital volume on the DAC should be good enough. The only DAC that had a volume control as good my best analogue preamp was the Lumin X1 DAC/Streamer with the Lindh volume control. That thing was almost perfect for volume but had some OCD gremlins that I am sure most would not have noticed or cared about.

Saying all that I always use a preamp, and all my DACs have no volume (a feature not a bug for me). I also listen at low volume on occasion, like tonight.

Another option is to get a Lumin U2 streamer (no DAC) and hook it up to your Bricasti DAC via AES, USB, etc. I am not a fan of Ethernet RJ45 streaming and the U2 will give you Fibre Optic streaming along with the Lindh volume control. You should be able to change the volume using the streamer if the Bricasti is set to fixed volume. I think I was able to also use my iPhone to adjust volume.
