Hi everyone, got a new guy here and one who’s not particularly technically knowledgeable.  Sorry.  Have several audio questions I was hoping the experts here would be willing to help me with but first a rundown of the component outfit.  My stereo consists of Magnepan SMGa speakers, a Denon DP60l turntable, Pioneer SG9 EQ, Carver C6 pre-amp and a Hafler DH500 power amp.  My questions are:

1.  What is the difference, if any, between the Carver C6 preamp and the Caver C16?  Are they identical except for the color or are there other differences?

2.  As you may have noticed, the only playback device in my outfit is a turntable.  It’s an LP only stereo so bearing that in mind, would anyone care to comment on my choice of components and their overall compatibility?  I understand that each person’s listening experience is subjective and it’s pretty much impossible to say what sounds good or not without actually hearing it but, all that being true, is it not also true that some components, because of the technology employed in their design and/or manufacture, may be inherently compatible or incompatible?  I mean yes, they all plug up together and produce sound and yes, you can play them continuously for a reasonable amount of time without starting a fire but, and here’s where I reveal how technically inept I am, is it such that because the hodgamatic circuit in the Hafler’s floogle board was engineered in 1976 and at that time they used the blue transistors with the red stripes instead of the red transistors with the blue stripes because well duh!, back in ’76 they didn’t have the red transistors but for that reason you really shouldn’t use a Hafler DH500 with a Carver C6 or the Maggies with the Hafler or the whatever with the whatever?  I mean do any of the components in my outfit not belong because technically speaking they’re incompatible with something else?  Does my question even make sense?

3.  I also have a Carver C1 preamp.  Which should I be using, the C1 or the C6?  I know, it’s all up to personal taste but I’d like to hear what the experts would do.

4.  All my components, with the exception of the Maggies, were purchased used off craigslist.  I’ve never done anything to these devices after having acquired them.  As an ignorant who doesn’t even own a soldering iron much less know how to use one (I do own a multitester but don’t know how to use it), are there things I can/should do to my components as like regular maintenance, i.e., open the cases and blow dust out, change fuses, oil knobs, shampoo circuit boards, etc.?

5.  Last one – The Hafler, to me, was expensive ($400.00), so before buying it I talked to a local repair shop and got some advice.  They suggested I take off the cover and ensure the capacitors weren’t leaking so that I did.  Bought the unit and all is good.  When the cover was off I saw several fuses in there.  My question is this; how will I know if I ever need to change any of those fuses?  With the case screwed on I can’t see them so am I supposed to change them per some regular schedule or just if/when they blow and how will I know if/when they blow?  Are there such things as permanent fuses that aren’t ever supposed to blow?

Thank you all very much for any help any of you may be willing to offer.

WELCOME!!
 
1.  The C-6 is older~ 
 
2.   Sonic Homophoby is not compatible with Maggies.....also, do you find the Maggies have sufficient bass without a subwoofer?
 
3.  (Seriously) The C-1 is an outstanding value in preamps.  You'd be hard pressed to find a better pre for anywhere APPROACHING the $$$ you can get one for.  What cartridge are you using with your Denon TT?  You might possibly find the C-1 has a better phono section than your C-6, but I defer to those who've heard both for a more definitive answer.
 
4.  Get a can of Caig DeOxit (5%) cleaner.  You, the DeOxit, and a handful of Q-Tips have an extended date with every contact surface & connection in your system. I recommend the 100% solution as a general rule; the 5% spray is cheaper but leaves more residue.  Follow-up with application of DeOxit Fader Lube for all potentiometers, etc.  Probably the most important thing you can do with an older component.
 
5. Fuses are a replace-as-needed component & shouldn't need any attention other than cleaning the contact areas with the aforementioned DeOxit.

Well, these are just my opinions.
 
  • We don't have any schematics for the C-6 or the C-16 and I've heard neither of them.  I'd been told that the C-16 was a C-19 minus the tubes, but that's hearsay.  We have the C-19 schematic and, except for the tubes, it's a relatively unremarkable preamp.
  • The Denon DP-60L is a very fine turntable.  I lusted for a 62L/67L back in the day.  More important to your preamp selection is the cartridge, however.  It's compatibility to the preamp's phono section can make a lot of difference.  I know of no incompatibilities between Hafler amps and Carver preamps.  Don't know a lot about Magnepan, though.  SOmeone else will need to fill that in, but 250WPC (DH500) should drive them sufficiently.
  • I know a lot about Carver C-1s and it is my favorite preamp save the C-4000.  Can it be improved — sure, and I've done some of that with replacing components.  It's pretty easy to match the phono section to any specific cartridge/turntable combination you have with under a dollar's worth of components.  As far a the C-1 and the C-6 go, you'd have to decide for yourself.
  • Just general cleaning of your connections.
  • You'll know when you need to replace the fuses.  The amp won't work.  Replace them when they blow.  However, usually internal fuses aren't meant to ever need replacing unless something else is wrong.
Hmm. line numbers seem to go away when you post.  That's rude.  Rich?
It should sound like it isn't there.

It is rude; evidently, the preview understands the <ol> and <ul> tags, but the post only accepts <ul>
Enjoy!

I thought I could see a faint image of the numbers.  Here's a set below.
 
  1.  
  2.  
  3.  
  4.  
  5.  
 Just the period after the number
It should sound like it isn't there.

Hey everyone, me again.  Just wanted to thank you all very much for all the help and answer the few questions that were asked.

I’m frequently asked that Maggies and bass question and do acknowledge that the bass provided by them is “weak” when compared to other speakers but personally, I don’t crave a lot of bass when I listen to music.  I’m a lot more concerned with clarity and imaging (I listen to a lot of acoustic music which might explain that) so I find the Magnepans to be perfect for my personal listening taste.

I keep forgetting to capture my cartridge model nomenclature.  I do know it’s a Stanton.  I think it’s a model comparable to their current MkIII but about 8 years older.  When it comes time to replace it I’m considering a Grado; whichever one I can afford at the time but probably in the $100.00 - $200.00 price range.  Anyone want to chime in with replacement cartridge suggestions?

I'm quite happy with, and recommend the 
Grado Silver-1 MM Phono Cartridge
that I received from RodH.
