| Parallel SET with sufficient power I'd be cautious in extrapolating from experiences others may report with various SET or PSET amps, unless they were using the same or similar KEF speakers. As shown in Graph 4 of this review the impedance of your speakers varies from around 3 oh... | |
| A speaker that looks like a driver or a driver that looks like a speaker? Kijanki, I’m thinking that what looks like the "spider" of a speaker driver at the front of the large assembly at the rear may signify that there is a large passive radiator somewhere. Perhaps the very large dome shaped surface behind the front su... | |
| A speaker that looks like a driver or a driver that looks like a speaker? Kijanki, under the "Technical Characteristics" link it indicates overall dimensions of 1200 x 1200 x 700 mm. The 11 inch woofer appears to be the lower of the three small circles near the front center of the speaker. And if you point to the double... | |
| A speaker that looks like a driver or a driver that looks like a speaker? Well, given their 4 foot diameter and their weight of more than 400 pounds per speaker they'll certainly make a statement in whatever room they may be placed. Personally I think they look kind of cool. I showed them to my wife, though, who is an... | |
| Why Single-Ended? Thanks, Peter. Regarding the first point, yes, a provision that an RCA input is to be used in conjunction with a jumper inserted between pins 1 and 3 of an XLR input likely reflects a grounding approach in the design that is non-optimal at best. ... | |
| Why Single-Ended? Lowrider, if you were to change from an amp having a single-ended internal signal path to a fully balanced amp I would expect that the differences in the intrinsic sonic characters of the two amps, and perhaps also differences in their interaction... | |
| Graphene spray and ... I agree with Geoff’s comment about the 200x factor. (Gee, that’s the second time in a week I’ve agreed with him :-))As can be seen in this Samsung press release the 200x factor applies to "electron mobility," not to signal transmission speeds. As ... | |
| Synergistic Red Fuse ... Oregonpapa 2-27-2017Joe Williams and the Brit, Al Hibbler, were two more favorites of mine back in the day. I've always loved Al Hibbler's classic 1955 recording of "Unchained Melody." How anyone could prefer the 1965 recording by the Righteou... | |
| Elrog 300B vs Takatsuki 300B tubes Ecx123, thanks for the additional info. I see what you are referring to in EML’s note 4, which states in part: Replacing 5U4G with 5U4GB may result in higher rectified voltage, so should never be done. Replacing 5U4GB with 5U4G may result in lower... | |
| Feedback through turntable Totem395 2-21-2017 Does the the issue arise even when not using the sub? Miner42, I don't think this question has been answered. Also, where is the sub located relative to the turntable and relative to nearby walls, and what is its rolloff frequ... | |
| Concurrent use of balanced and unbalanced outputs: Lamm L1 You’re welcome, Ohlala. However output impedance rises to 3.35K and 7.7K at 20 Hz are fairly extreme, and are definitely not consistent with "high current drive capability" that can handle any "real world load." Also, the line level input impedanc... | |
| Elrog 300B vs Takatsuki 300B tubes Ecx123 2-25-2017The Franks use 5U4GB and Isreal says they are different than even 5U4G. I believe he said 5U4GB takes more current. A 5U4GB can **handle** a somewhat greater output current load than a 5U4G, but their specs are otherwise pretty ... | |
| Why Single-Ended? Can somebody give definitions and explain differences between ....First, keep in mind that these terms are often bandied about in a loose manner, and some are inherently ambiguous. So you may frequently see a given term used to mean different thin... | |
| Concurrent use of balanced and unbalanced outputs: Lamm L1 Thanks, Bob. Ohlala, the answers to your questions depend on the specific designs that are involved.First of all, though, I would keep in mind that most XLR-to-RCA adapters short the signal on XLR pin 3 to ground (XLR pin 1). That would be appropr... | |
| Can Pass XA60.8's drive Revel Ultima Salon2's without their tongues hanging out? As a point of information, I suspect that the "122 watts peak" specification of the point at which the amp leaves class A corresponds to 61 watts based on the usual convention for defining amplifier power (volts x current with each defined on an R... |
