SIMPLY AMAZING: Coda Technologies 07x Preamplifier


I have in-house Coda Technologies 07x preamplifier, which is the latest iteration of their '0' series linestages.  Very briefly, over the last seven years I have had over five solid state preamplifiers, price range was between 4K to 20K, in for auditioning in my system.  They were quite good, but lacked what my tube based linestages had to offer.  The solid state pieces were wickedly transparent, micro-detailed, tight accurate bass extension, and had great overall dynamics.  However, they lacked the organic timbres/tonality, 3D imaging, and the ability to create a sense of space between the players that my tube based preamplifiers produced in my system. 

So, I was concerned that based on my personal preferences that the Coda 07x might not be my "sonic cup of tea".  Boy was I wrong!  Besides, the superlative build quality, starting with the double-sided gold-plated circuit boards, and the sane prices Coda charges compared to other much more insanely priced gear, the 07x is priced at $6'500, this preamplifier has patiently shocked me regarding it might be the best synthesis between what solid state offers (transparency-clarity/low frequency extension-control/micro-details/speed-dynamics) and the best of what tubes have to offer (pristine timbres-tonality-color/holographic imaging/three-dimensional sound-staging with a sense of air around the individual instruments).

Coda always, at least in the America "flies under the radar" compared to other US manufacturers, but based on performance, build quality, and  smart evolved engineering they offer cutting edge equipment at reasonable prices that deserve to be heard by more music lovers. I'll get into all the little details in my review on the performance of the 07x, but for right now if you are thinking about purchasing a solid state linestage, consider giving Doug Dale a call to hear this very special piece.

1. The remote control comes from Coda pre-programmed. At least this one did. This one is a universal brand mc-450. 2. There is no on/off switch. The only option is a mute function, that sadly, is only operated via remote. 3. Yes, I have noticed the source bleed as well. Shutting off the one source when using the other cures this. At least on this one it did.
wturkey, what sources were you using and on which inputs when you noticed the bleed? I’ve only ever used the Balanced 1 input, but if two users are getting source bleed that implies some issue with the relay implementation right? Unless you were both using tuners and maybe that’s the issue. 
@wturkey Thanks. I love the sound of the preamp. I mates well with the D-sonic amp I have. Though I am a disappointed in the spartan feature set. A mute button on the unit is needed. Along with a trigger and a standby.

The bleed is not a big deal.
@rlovendale I will test this again tonight with 2 DACs. I know Tuners can bleed with other gear I have used. I will use Balanced 1 and 2 for the 2 DACs I will be testing with.
rlovendale. Will have to double check on that one. I noticed the bleed, for the first time, about a week ago. Will see if I can replicate it and provide an exact answer regarding which input, etc. When it happened, it reminded me of a Hafler DH-110 from years past. It had the channel bleed as well.
