The revolution has begun!

Digital amps along with digital xovers are the future.....and you can have it NOW. I am not going to say that a $1400 Peachtree GaN1 amp will sound better than a $120K MSB Select, $145K Boulder Preamp and Bouder $250K mono blocks with $20K worth of cables in between (over half a million plus power cords and amp stands)......but it did beat the Holo May KTE with the Holo Serene Pre and Kinki B7 mono blocks with $1000 worth of interconnects ($13k). So what will it take to beat this $200 digital board from Elegant Audio Solutions powered from a $100 switching power supply? With a digital amp you do not need a DAC or a preamp or regular amp with feedback, tubes, or transistors. With digital amps you can bi or triamp your speaker drivers directly without the distortion of passive components. In fact, I would bet that if you bought two GaN 1 amps, bought the $600 digital xover from minisdp (with great linear supply and great coax cables) and biamped some drivers directly that it would sound better than most $50K systems. You could get 2 12 inch woofs and mount them on an open baffle and put a beryllium tweenter on top and set the xover to 1K or less (48db per octave). You hardwire your speaker cable to the woofers voice coil wires and use Music Purifiers and Ground Enhancers on each driver.....Bybee Clarifiers on the back of the woofer magnets.......speaker wires hardwired via plastic clamps into the amps (no binding posts or spades allowed here!). Of course, you can triamp.....and manufacturers will soon have powered digital speaker so all you will need is a source.

There will be other manufacturers designing and building digital amps that will (no doubt) be better than the EAS boards.....but they will come at a price. These, yet to be made digital amps will blow the industry wide open....as no more big heavy expensive boxes will ever need to be purchased......but what EAS has not is fantastic. When I do some mods to the Peachtree amp next month it should get a step or two better. Have fun!

I have started a webpage about all this and more and will be updating it continuously.

A "transport" is just the spinner in a CD player.  Almost every CD player has a coax digital out so can be used as just a "Transport".  Your Audiolab has no DAC in it so you call it a transport rather than a CD player.  Any player including universal players like an Oppo can be used via its coax out to the flex and into a digital amp.  However, you cannot play an SACD into the flex.....nor is SACD info allowed out of a normal coax out.  The amp and the Flex are PCM only devices.  You could make an integrated amp with digital amp modules where you change DSD info to PCM before it goes into the main pcm to pwm conversion.....Technics does this.  You can burn your SACDs to a computer and use software in a computer to change it to high speed PCM and then output that to a streamer like the IFI Zenstream to play through digital amps.

You get a Flex and a single stereo digital amp and you have a blast....you add a second amp and get rid of the crossover in your speaker and you are in heaven.  No more bass nodes.....full equalization......no more binding posts....no more passive xovers.....just pure sound.....dynamic as hell.  Fun times await folks......the future is now!

@tweak1 Yes, I did get it modded by Ric. It was an improvement over stock, especially on the top end. I had another amp that had more low-end power but not as good on top, I sold the Voyager because I wanted more power for the bass with my old Thiel CS3.7. Everything I just mentioned was sold.

Needing more umph over the PS Audio M700s is why I bought Rics EVS 1200. Unfortunately, both my cables (Series 8 Wire World and Boutique PCs that didn't plumb the depths compared to what Im using now), and a Solid State vertical rack got in the way of my hearing what it is capable of. This was remedied when I came across a solid maple table (5 X 2 x 2") locally for $270!, and in the process of moving the kit out of the vertical I rested my V on a floating platform from which it slipped off. That would have been ok, but I had the top off and resting sideways on top, so when the amp slipped off the top nose diving into one of the modules. It looked ok until I turned the system on I had major fireworks, and so installed the EVS 1200. As much as I raved about it in a long thread when I first got it, which Ric asked me to take down for health reasons he wasn't going to make any more of them, the Voyager bettered it then. And so, it sat on the sidelines. Glad I still have it

@tweak1 Sorry to hear about that mishap. That was a very good amp. I have mishaps like this with my audio cables because I am always tinkering with placement and other gear combos.

I also keep my audio stand as far away from the speakers as possible. 

I believe I get delivery of the GAN1 on Tuesday or Wednesday. Along with a WyWire SPDIF cable with BNC to RCA termination. I already received the streaming addition I needed, the Sonore UltraDigital to connect to the GAN1. However, the mystery is if it will actually work via my ROON READY Sonore OpticalRendu. I have feedback from the guys at Sonore and 2 of them said it will work and 1 person said no. I need to make a ROON READY Endpoint change from FIXED to the other option (I forgot what that is). This is where the mystery lies of whether my setup will work with the GAN1.

VTV just released a digital amp that uses a more powerful version of the EAS board.........The VTV D300 is now being sold:

The reason it says Purifi on the faceplate is that he does not have any faceplates with D300 on them....He will allow you to change the faceplate for free when he gets the right ones in. I don’t think it even needs to say anything on the front except VTV.

The reason he rates the amp at 300 watts into 8 ohms when the module is rated at 400 watts is that the power supply dips in voltage when doing full power tests with both channels at the same time. If you did peaks on one channel at a time you would indeed get 400 watts of unclipped power. Most music has peaks that require the higher power.....hardly any music requires 400 watts continuous on both channels......and if you played it that loud....you are not smart......hearing loss, indeed.

The WBT-0703Cu jack option is a nice upgrade. Of course, I will offer mods on it. The digital amp game keeps getting more interesting. I cannot wait to bi-amp my speakers with these things.
