Amp/pre compatability It is the pre-amps output impedance that is important relative to the amps input impedance. Considering you amps 50K input impedance, if the pre-amps output impedance is less than 1000 it should be OK. Less is good. If it is 3500 or more it could ... | |
I have a buzz You probably have a ground loop. Assuming that is correct you need to identify the source. I suggest you not only disconnect but unplug everything connected to your amp (except the speakers of course). Turn the amp on. Any buzz? I suspect not, but... | |
Integrated Tube Amp for Spendor SP7/1 $1000 It is hard to go wrong with the Primaluna and Cayin integrateds. If you are patient and fast (when they appear) you can get a Primaluna Prologue One on AGon. I use one now as an alternative to my big Cayin which is outside of your price goal. It i... | |
How do you judge your system's neutrality? Mapman, IMHO your last two posts are the soul of great wisdom. I can't believe that this thread is still alive, and, apparently, well. :-) | |
integrated amp suggestions solid state What is your budget? What is the efficiency of your speakers, what is thier nominal impedence and what is their minimum impedence? Knowing this will make recommendations more meaningful. | |
Ebtech's Hum X Ground Loop Exterm. Do they work? FWIW when a hum increases when you turn up the volume it is unlikely that it really is a ground loop and I would doubt that a ground loop exterminator, whether a cheater plug or a more 'sophisticated' one would help. But you might try identifying ... | |
My system's high frequencies hurt my ears OK my assumption that your listening position was further from the speakers than the speakers are from each other makes my suggestion a bit obtuse. Lets see if this will work, rotate your speaker(s) until the axis is approximately 18 to 20 degrees... | |
My system's high frequencies hurt my ears Without knowing specifically what your set up looks like it is hard to tell when you will have maxed out the toe in but, assuming that you are listening in a traditional triangle set up, or something close to that, take a piece of paper and draw y... | |
rack mount ? Frankly I'm not sure how much difference it will make. Heat normally rises - and this heat will affect the temp of the components above it. You really want to break up the column of heat from the amps and a using fans directing heat in a horizonta... | |
My system's high frequencies hurt my ears Try toeing the speakers in until the axis of the speaker crosses well in front of your head. Some of the excess highs might be from the first reflections from the side walls. This will also change the back wave quite a bit and could lower high fre... | |
Vacuum Tube Display Case I use the expanding wood trays used for storing silverware in drawers. I use cardboard inserts in the individual sections to separate tube type/brands etc. You can find these at most any store that sells kitchen supplies or big box stores like Cos... | |
Vocals sound slightly high pitched? Most likely VTA. Try dropping the tone arm a tad from horizontal (assuming that is where its at) in the rear. Nlot much a mm or 2 could do it. | |
Speakers with no rear wall, better or worse sound? Problem is that 'accurate reproduction' is such a moving target, especially when most recordings are hardly 'accurate reproductions' of a live event in the first place. Most recording efforts to produce accurate recordings come from classical musi... | |
Speakers with no rear wall, better or worse sound? What I have found, while setting up both panels and boxes is that the existence of a wall behind the speakers is best so long as your speakers are about 5+ feet away. Adds a bit of 'body' that can disappear if there is nothing there provided the s... | |
rack mount ? I don't know what kind of fan you are using, or if you rack is enclosed. Assuming it is not inclosed, and assuming you fan will move the air horizontally, I'd put the fan on a level at the top of the upper amp so the combined heat of the amps is d... |
