That looks slightly different than the custom ones Woo is using, and I'm sure a MATCHED quad is needed.....so probably more $.

Has anyone heard how much it will cost to replace the tube quad?

Hello AcousticMatt, Did you get a chance to try your WA23 and Feliks Envy as preamps into your speaker system? I have an electrostatic speaker system and am thinking one of these SET preamps would be just the thing to "soften it up." If you did, was one clearly better than the other as a preamp?

If an owner were to take advantage of the trade-up program and send in their original Aperio, does Warwick literally take apart their old unit and change out the parts to turn it into a GSE edition, or do they accept the old unit as tribute (recycling the parts therein) and instead send out a...

I own the Shangri-La Senior system (including HiFiMan’s own charger) and just want to encourage you to have a proper listen when you get the chance. This is one of those setups where what you get out of it will be directly proportional to what you put into it. This system is so ruthlessly...

The Cybermen episodes were my favorites from Doctor Who growing up! Thanks for a smile 🤙🤙

I think theveterans is saying that the WA33 is a good amp to use with the Immanis via the Raal Transformer Interface, and I hope to find the same thing when I get an Immanis (hopefully next year).

Would you say it’s more euphonic? And if you do compare them, how does the bass compare?

Very much sharing the same question! I just recently became aware of the existence of the Mass-KOBO 465, and of the great accolades/furor it seems to be receiving/generating. Can’t help but wonder how it compares to a WA-33 EE w/JPS wiring and upgraded tubes, although one notes immediately...

My vote: the middle one. Hoping to join you as a happy new Immanis owner later this year!

Awesome stuff you have there! Please let us know your impressions of various headphones on the MK465 vs. the Aperio 🙏

Ah okay. So when you flip the switch up from Warmup to On, it has to go through the Off position?

I'm interested in the Viva amplifiers, and recall that in one of the Abyss videos made by Joe and his sons, that they recommended against them due to problems that these amps caused for the headphones due to the amp's startup sequence. I've been Googling around for a while, trying to learn what...

The ones that Woo used to sell (and that used to be available from many other online sources) were the 2A3 HP, which had a slightly different size, appearance, and a white base. Three of my four original HP's are still working, and I had one of the non-HP kind to roll in and try, but they don't...

It looks like the KR Audio 2A3HP's have gone out of production, and aren't available anywhere. Does anyone have more information about this?

Both. Get both!

If it weren't a terrible inconvenience, Warwick could set up a whole new buying option to address people's FOMO, in which one could choose the base electronics unit's color separately from the headset (e.g., order the silver base unit and the gold headphones :o2smile:). On a more realistic...

At this point I'm completely uncertain. While it would take quite a while to save up the money for any Aperio, it would take a lot longer to save the additional money for the gold version. Furthermore, its looks are frankly ostentatious, both repellant and mesmerizing in the very same second...

I can't believe it, but the Warwick Aperio website reports that the gold version has more carefully-selected, better-matched driver pairs. Has anyone heard the gold Aperio and compared it to the sound of the other colors? If so, did you find the difference audible?

Un huh. Just as we all suspected. Joey is in, shall we say, "problem management."

Just read through that thread and am enjoying it thoroughly. Thanks for that!

To my ears, the SuperConductor cables made it an overall more balanced presentation for either headphone: voices sounded more natural on the 1266, and on the Utopia, bass was brought out and tizzy highs were tamed.

Hi Tony! I concur and want to recommend to you to try the Utopias with a good tube amp and the JPS Labs Superconductor headphone cables (although you'll need an adapter to hook them up). I use that arrangement of the Utopia with my Woo Audio WA-234's (selecting tubes that bring out the bass)...

Wow six months! Did Sennheiser give you some idea of when to expect delivery? Please let us all live vicariously through you by keeping us apprised of your progress!

I see on their website that it is currently unavailable. Please let us know how your ordering experience goes!
