    The grills are cloth. Magnetic grills typically work by embedding magnets in the frame of the grill (which is usually plastic and I think sometimes MDF), not by being metallic. There are some metallic grills out there (e.g. ATC), but they are rarer and typically have a more open mesh than cloth (you can usually see through a metal speaker grill).

    I've been off-line recently and just saw your earlier posts. Let us know what do you think about these special 40s. They look beautiful in the room. I sold them last year and kept the original LS50 mainly due to the synergistic with my current low-output power amp. Many say that the Dynaudio speakers need power, a lot of power. Also, they do require relatively long break-in time and dynamic music for break-in. The Dynaudio official website recommended electronic music such as those from "Aphex Twin" and "Kraftwerk" for break-in.

    Some rolled up tape (or double-sided tape) on the floor and/or on the speakers themselves will usually teach cats very quickly to stay away. The first time they encounter tape might have them panic and blitz around the room if it gets stuck to them though, so be warned.

    For helping cats to peacefully coexist with speakers, no amount of deterrence ever worked in my case with my Maggies. I tried all sorts of stuff like double sided tape on the side of the grill cloth, rubbing orange peels or citrus essential oil on the wooden side rails, setting up motion activated compressed air blowers near the speakers, loud noises when she approached, etc.

    What finally worked was getting a tall, sisal (not carpet) scratching post and putting it in the same room as the speakers. I'd ignore all carpet scratching posts and any of those cheap horizontal cardboard scratchers. Think we used this one: https://www.amazon.com/SmartCat-3832-Ultimate-Scratching-Post/dp/B000634MH8/.

    I would regularly rub catnip into it at first, and leave treats on the top or around the base so she'd be interested in it. Then praise her when she would use it. Cats have a natural urge to scratch, so I think this worked because it allowed her to satisfy that urge while realizing that the scratching post better fit that need than anything else. Never had an issue with the speakers again, even after moving and putting the cat scratcher in a different room at the new apartment.

    Great ideas that don't always work when your cat has a tendency to act maliciously when he wants attention. This guy coexisted peacefully with my subwoofer grills for a bit over a year before shredding them both in a bid for attention. He also thinks double-sided tape tastes great, so that kind of thing doesn't stop him for long.

    And so my Maggies live behind a closed door in the no-cat zone.

    I have heard a SV2A3 and owned a clone. They are good because of their simplicity. Tamura transformers have a certain sound that you may or may not like depending on your taste and experience.

    the problem with that ad is the price is pretty whack. Sun kits have become increasingly difficult to source in the West for some time, in the East they are a more modest value proposition. for that kind of coin you could get a much better 2A3 amp.

    lastly, I am 95% sure that amp is 100V AC input only.

    Yeah, I thought for a moment about grabbing one from VKMusic, but perhaps better to wait for some of his Sun imports to come up used. There's still some confusion as to whether he'll sell kits vs. completed units, if I recall.

    I was wondering if anyone could share their opinions on the Klipsch RP-8000f versus Madisound's BK-16 or BK-20 kit?

    I understand there are quite a bit of differences between them, most obvious being the Madisound kits are DIY.

    I was thinking of feeding either the Klipsch or BK-16/20 off the speaker taps of my Eddie Current Aficionado.

    I have read here at SBAF that the Fostex drivers, especially the upgraded Sigma ones, are quite good. So I'm wondering if I should just resist the sale price of the Klipsch speakers (please see Deals thread) and go for the Madisound speakers instead?

    I have somewhat old ears, so my listening preference would be something like a UERM but with more bass body and extension. Thanks!

    Asking a question for my cousin as I don't deal with vinyl:

    Any suggestions would be greatly appreciated.

    It doesn't tick every single box, but maybe a Pro-Ject Pre Box DS2 Digital? At a cost conscious price point going integrated rather than pre/power might be a better solution; maybe something like the Audiolab 6000a Play? However, for more $$ the Peachtree preDAC is the only other thing that comes to mind immediately.

    Definitely sounds like a bit of a niche, with the MC phono input. We're likely going to end up looking at more "mainstream" brands. Maybe the Parasound P6? It's somewhat expensive and I haven't heard it, but it checks the boxes

    You didn’t mention budget. If he’s looking for something in that price range, not sure there’s any other choice. If he wants to go pricier and better quality, and throw in streaming with an excellent streaming app (BluOS) as well, Nad I think has the C 658.

    Just saw this. I've been using a PT1 for the last 3 years and it has been great.

    Just wanted to confirm something, i'm using the iloud micro active speakers which has 2 inputs, a 3.5 and an RCA, i can connect 2 separate sources to it and i should be ok right? Obviously i wont be playing music to it at the same time, but even if i did I assume it should work like a turntable mixer and shouldnt damage anything right?

    It should be fine. Maybe you'll get some ground loops, but if it's not loud/noticeable at your sitting position then who cares.

    A moderator on the iLoud forum uses it exactly that way: https://cgi.ikmultimedia.com/ikforum/viewtopic.php?f=40&t=27181

    thanks guys. though, maybe its nervosa. but i realized there's juuuust a bit of noise when im connected to the PC (ieven if its by itself). So to minimize polluting the noise floor, i'm gonna just switch the sources and feed just one at a time for now (until i can afford like a goldpoint switch or something)

    *EDIT* Confirmed this is due to the fact that the Kinki EX-M7 is single-ended topology. Pin 3 (NEG) drains to ground through a resistor so it is effectively cutting the voltage input to less than half I guess? So, I just need to use the RCA in/out.

    I need some help understanding a mismatch of pre-amp and power-amp in/out levels. I just got a used Kinki EX-M7 power amp. I know the balanced inputs work because I listened to it for 2 hours with the previous owner's system. He had a Kinki pre-amp in the chain so clearly the levels there are properly matched.

    My preamp is an Audia Flight FLS-1. I typically use it with an FLS-4 power amp, but it is crated up and I am not going to use it until I move into a more permanent space. When I run the FLS-1 into the EX-M7 using balanced in/out, the preamp cannot drive the power amp to reasonable levels until I am maxed out on +10db volume. The preamp has a gain adjustment of +6dB which I have also added, and that still drives the power amp to barely audible levels with the balanced output. If I use RCA single-ended from the FLS-1 to the EX-M7 it works as expected. The EX-M7 is single-ended and the FLS-1 is fully balanced internally. Would this result in a mismatch of input voltage for the EX-M7?

    The Kinki EX-M7 seems to have a low input sensitivity of 1.45V RMS. My FLS-4 power amp has an input sensitivity of 1.41V so that shouldn't be an issue. As far as I can tell the FLS-1 and EX-M7 both have the typical XLR pinout where 1 = GND 2 = POS 3 = NEG.

    What else am I missing here? I have a couple other devices I can use to test to be sure the pre-amp is working properly. I don't have any major concerns for it being broken or malfunctioning, but later this week I will go deeper.
