Have you tried Red Wine?

Drubin,
The only D amp I have used other than my Vin Rose is the Rowland 201 with Ice Power and a lot of experimentation took place between these experiences. Off the top, however, I would credit the Clari-T with higher resolution and a more lively presentation. The Ice had better bass but that may be due to having more than 40 times the rated output.

I had to find out for myself, so I called Vinnie this morning and ordered a Sig 30 and a DAC. Last week I received the Zu Definition Pro speakers like Srajan uses and I'm hoping that the new Red Wine amp works as well with them as he says. Does anyone have any more info on their Signature 30 experience?

Good for you Macrojack !!

I haven't heard the Sig 30 myself. But from the comments on Audio Circle it's a winner! I only have experience with the ClariT and RWA Teac from Redwine Audio.

With the help of a good friend, I'm finally about to have my battery powered 50 wpc 8 ohm,100 wpc 4 ohm T amp completed in the coming weeks. 30 battery wpc isn't enough for my speakers as I discovered when auditioning the RWA Teac.

I've always felt the PIO caps could be the magic bullet for these amplifiers. I opted for the Mundorf Silver PIO caps to be used as coupling caps in my integrated instead of the Jensen(mainly due to the cost). My unit will also use a Endler 24 step 4k ohm attenuator instead of the DACT. I'll have 12 SLA batteries wired up in a custom made maple stained wood chassis ( had to match my speakers LOL) using the 2022 chip instead of the TK2051( found in the Teac and Sig 30). It will also have the Eichmann Gold CablePod binding posts instead of the basic gold plated brass post.

Definitely not a copy of the Sig 30, as I started this project over a year and half ago. I just never seemed to get it completed..until now. The Sig 30 review gave me new hope in having this amplifier finished.

I found the ClariT more pleasing too my ears than the modified Teac. FWIW the ClariT doesn't have the deep bass because of the chips original design. If I remember correctly ..it was the original coupling caps value which impeded the amplifier from having bass below 100 Hz or so. This shouldn't be a problem with the Sig 30.

When using powered subs it is much more difficult to hear the true frequency response of your amplifier and source IME.

Good luck with your new toys!

OT, sorry...

Excellent Gmood1!!! Do you have pics? I'd love to see your setup. I built a similar power supply for my UcD's, but at +/-48v. I cheaped out and used Burled Walnut veneer on mdf though :-)))

Hi Gordus,
I will post some pics as soon as I get the unit back from Utah. I'm very excited about this amplifier! I hope it can at least match the sonics of my Audio Sector integrated. Hopefully it will exceed the Op chip amp! :-)

This is something the ClariT nor RWA Teac could do. With over $500 just in parts, it should be several steps a head of these two units. Not that better parts will always equate to better sound,but I'm sure it doesn't hurt.;-)

Gordus that's a lot of power for batteries!!! I've read the UcD's are excellent amplifiers in the right systems also. In the future, I hope to be lucky enough to hear one.

By the way, thanks for sending me the Empirical Audio modified Electrocompaniet ECD-1! If people think digital is fatiguing, they haven't heard a Dac like this one!
