VTV D300 Digital amp

sirnui,

Way to go....you tweaky dude!

You and I have the only VTV D300 amps in existence (more coming soon). Right now I am working up mods on the Peachtree GaN 1 (brother of D300). I will be doing the same mods to both amps. Please try some better speaker output wire. I will also be offering my binding post bypass system using quarter inch nylon bolts, nuts, flat washers and wingnuts used as a clamp. This is even better than the WBTs but you cannot use banana plugs.....only spades and bare wire. All speaker connectors suck....please use bare wire or tinned bare wire everywhere you can and especially on speaker cables. I have been hardwiring my amp to my speakers for over 35 years!

Thanks for posting your sonic findings.....most people have no idea how simple mods can completely change and improve the sonics of equipment (and the mods you did will have no impact on measurements....none). I have been tweaking since the 70s.......he he....since I am in my 70s.....maybe that is not so long.

Have fun!

I have to disagree. I’ve been modding/tweaking for many years...

I have never heard any audible/musical improvements with any modifications to the power side of any electronics. I have done my mods to simplify the signal flow (removing fuses/switches), upgrading contacts (pure copper), more robust/solid connections (solder), and better wiring (OCC, Triple C). For me, as an engineer, purist, it’s a fun hobby.

If you really need to mod some parts of their equipment for better performance, shame on the OEM.

I have ALWAYS (since the early 80s) heard a sonic change with every single thing I have done to the AC power inside a component..  To each his own.  What I did to the GaN 1 the other day was mind blowing....all it was....was purifying the AC going into the amp.  It completely changed the character of the amp....way better sounding.

ricevs,

Thank You ... again.  Cheers to the VTV D300 and tweaking!  I've done plenty of tweaks outside of boxes and in between boxes but I've never seriously done tweaks inside the box.  Now I know first hand what can be achieved by doing this.  My speaker cables have BFA connectors so I won't be following you down your route with binding posts but I do plan to change out the internal speaker wires with more Neotech Solid UPOCC copper wires.

I also use the VTV D300 to listen to headphones using a Zynsonix speaker amp to headphone converter. If I ever make the D300 a dedicated headphone amp or if I get a second D300, I may just hardwire the converter box to the boards on the amps!  Thinking about it some more, there is some space inside the D300 that may allow me to put the internals of the converter box inside the D300. This should allow me to cleanly hardwire the internals directly to the EAS board. 

Remove the speaker connectors from everything......I have not used speaker connectors in over 30 years. Your amp can drive headphones without resistors and junk. However, with a digital only volume control.....you will need a digital volume that has no losses at very low volume.....like the Leedh.....if you have that then why would you want a converter box with all its veils?.....since you have Leedh....give it a try.....start out with lowest volume and turn it up slowly. If you do not have enough control over the volume then you may have to put resistors before the headphone....but why use connectors....just use plastic clamps....or attach tinned wire with resistors (if needed) to your WBT jacks and the other end of the wire to the headphone jack. By the way, I also hardwire my headpones....just clamp the wires from the resistors (if needed) or wire directly to your headphone wires. Why have connectors on your headphones? I also modify my headphone so the headphone wire is hardwired to the headphone driver......LESS IS MORE!
