From running sine waves from 6 to 20 Hz from Room EQ Wizard's sine wave generator, it seems I can hear below 20Hz. With the same method I have noticed amplifiers actually do differ in how far below 20Hz they can go. Also music played with below 20Hz cutoff activated with software always sounds...

@iFi audio the marketing materials here state that "The Quasar has no shielding to reduce the capacitors designed for high powered amplifiers." That seems like a translation failure or something like that, I believe the correct phrasing would be "to reduce capacitance". You may want to have that...

Found this at a retailer's website.

For myself, Monoprice's high EU shipping costs have always included EU VAT so I didn't need to pay that afterwards. This has also been confirmed to me by local DHL staff that handled the customs process. It is a bit strange though that this is not explicitly stated anywhere on their site.

Liquid Platinum DAC down to $275 with code SUPER25 Edit: look like this item is actually excluded from this "sitewide" promo code. So it is actually $299.99.

Monolith M1070C down to $167.99 with code BIG30 :astonished: Edit: Liquid Platinum DAC down to $299.99

Monolith M1070C $195.99 with code BIG30 (Code applies also to THX 887 and Liquid Spark amplifiers)

The USB module's firmware can be user updated. However, the firmware for the rest of the dac can only be updated by the official distributors.

Hmm three. May, Asterion, Gustard A22.

Since there weren't any photos of the amp's internals anywhere, I took some: Top side of the amplifier circuit Bottom side of amplifier circuit Dac module Some observations: There are nine electrolytic capacitors on the amplifier, which are 3* Panasonic FC 470uf 63v 4* Nichicon VZ...

Halgorythme is an amp builder based in France. They have a 300B headphone amp for a semi-reasonable cost of 3200€.

I am going to order a pair later this month to try. I've liked all other JJ tubes I've had. Their e88cc is my #1 driver tube for the CK300 and I prefer it over nos tubes I've tried. It's particulary strong on bass extension and subbass. Their GZ34S is also in my top two rectifier tubes for it...

Finally got around to flipping the tube sockets around. This was however not primarily motivated by aesthetic reasons but a need to clear up some space inside the chassis for... something, that should arrive in a couple of weeks. Have to say the HE1000V2 has really surprised me. They have...

Hi, I am interested in the Europe tour. I live in Rovaniemi, the Lapland region of Finland. My "audio past" goes back to 2002, however I have become more invested in the hobby in the last five years. I generally prefer closed-backs over open-backs. My list of HPs incluedes Focal Stellia...

To make this question more difficult, are there perhaps any portable tube headphone amplifiers made in EU(r)?

I've now had the M1070C for about 3 months and after some (extensive) modding they've taken over the spot as my #1 headphones from the (extensively) modded M1060C. These are quite hard to drive with 60 ohms impedance and 90db sensitivity, roughly the same as Abyss AB1266 but less so than...

So, at what operating point are you running your tubes?

$288.99 also on monoprice.com with code MARCH15

Western Electric WE300B, JJ Electronic gold pins ECC88, Philips Miniwatt metal base GZ34. My favourite tubes so far.

While browsing Aliexpress today I came across a chinese tube manufacturer that I couldn't find any previous mentions of on head-fi - Golden Voice tubes with website at gvtubes.com. They have four different 300B models, two of which are higher end models, "WE300B Plus" (first picture, $880 for a...

Well, I can confirm they have not failed in the less than 30 hours that I've used them. However, there are some other models to be found on Aliexpress that are cheaper still.

The Linlai 300B-T has an unusual combination of mesh plates and semitransparent black spray coating.

This has me thinking you could put one of those patterned candle covers around the Elrogs to project various shapes around the room. Such as this;
