Bookshelf/Small Speakers
Don’t overlook the Aerial 5T. It is similar in design to the Salk that Hilde recommended. These are great sounding bookshelf’s but are power hungry. If you’re going to use your Carver you should be in good shape. Not sure what your tube amp may be... 
Jumper wires/ cable suggestions
Hi Patrick,Some food for thought: Your Vandersteens are 8 ohm and since you'll be using your 275's in parallel, you will be using the same 16 ohm taps (for your speakers) that the jumpers utilize as when set up in parallel. The MC275 in parallel -... 
garrard 301 - how to polish chassis paint.
bestgroove is correct, UV light will cause resinous plastics to yellow. For some resins, the hardening component (by itself) when exposed to UV will turn Canary yellow ! These resins are very high quality but have this Achilles heel. Dab on (incon... 
Output Impedance and Speaker Impedance
@pragmasi - Even though I'm past the warranty I would not feel comfortable rigging up an attenuator. No offence to your suggestion, I just don't trust myself. I wish the 275 had balance inputs but no such luck. However, with the 5T's connected to ... 
Output Impedance and Speaker Impedance
@ atmasphere and George, that was kind of what I was thinking. I have a vintage pair of 601 IV's that I had since college and I played them at "11" (Spinal Tap reference) all the time. It's really the only way they sounded decent. I had the driver... 
Output Impedance and Speaker Impedance
@bdp24 Thanks for the info. SS and tube power is a perplexing, abstract concept. I'm still trying to wrap my head around impedance, volts and wattage. But what I do understand, traditional tube amps do better with higher ohm rated, more efficient ... 
Output Impedance and Speaker Impedance
Thanks again George. As I get more in to this hobby, seems I'll need to do some reading on classes of amplifiers and speaker pairing. There's a lot to learn. I have a Unit Atom and when the firmware went awry with my 7900, I hooked up the Aerials ... 
Output Impedance and Speaker Impedance
Thank you ALL for your responses. I'm relatively new to AG and lurk daily, but do not have much to add to the knowledge base so I don't post frequently. Really appreciate the knowledgeable veterans replying to my inquiry. Regarding the responses:@... 
MA7900 anyone experience problems with firmware ?
I'm back in business. Turned out to be an issue with the firmware again. Pretty simple fix... un-bricked the 7900 by shorting (depressing) the TST which is a (labeled) button on the circuit board, plugging it in for 15 seconds (while holding down ... 
MA7900 anyone experience problems with firmware ?
Dave & Andrew, thanks for your replies. Considering it’s happened twice, I’m going “by the book” on this. Boxed it up and returned to the dealer. Microprocessors are way outside my wheelhouse. The manual recommends holding down the power butto... 
MA7900 anyone experience problems with firmware ?
thanks Elizabeth, hoping they'll stand behind their product. I'll report back my experience in resolving this issue. Pretty inconvenient packing up a heavy amp and even worse.... no music for awhile.
