amplifier for large advents?

Hi Dfwlistener,I have a pair of Large Advent speakers and I drive mine with a vintage Marantz 2275 receiver and they sound wonderful together. You ought to consider this receiver , I think that you would be very surprised.

Dfwlistener: The crossbraces get glued inside. Pretty easy to do even for a klutzy non-woodworker like me. Buy some maple 1" x 1" stock at home depot.. just measure very closely and over cut not undercut until piece fits snub between front and back baffles.. glue in with wood glue..
I used somewhat inexpensive "gold plated" connectors from parts express as I did not want to spend hundreds on connectors. I used the Swedish made 12 gau wire from Madisound web site with good results (I've used this in all my speaker rebuilds.. inexpensive and sounds pretty good.) I used a couple of Kimber caps to get the right value, this improved midrange warmth and glow. There was a guy on ebay did crossover kits for these and others.. for AR speakers as well. Also he had some really good vintage looking grill cloth for AR's that I used on my advents and they look great. One thing I did was remove the inner black grill cloth to reduce the amount of fabric 'blocking' the sound. I also removed the fried egg tweeter metal grill, you have to be (obviously) very careful with this, but it opened up the tweeter dynamics a bit.

The amps one already have sitting in the attic are definitely the right ones to try! :^)

The Harman Kardon receivers from the early '70s sounded great with large Advents then and still do. With dual power supplies and lots of point-to-point wiring, they have a muscular, tubey sound. A friend powers his large Advents with the H/K 430, and I use the same model with ADS L1290II in a secondary system. Only rated at 30 watts but it plays bigger, and is considered the most reliable of the x30 series at this point.

Mr_hosehead - thanks for the ideas. I had forgotten about Hafler. Those were pretty good in their day. I also forgot until you mentioned it that I have a pair of B&K mono amps in the attic. I'll try them first.

Xiekitchen - I was thinking the same thing. Have you replaced the connectors? What did you use? Does anyone do a crossover upgrade/rebuild service? Did you put the braces on the inside or outside?

For sound more towards the warmer tube side of things, there was a pair of TAD Hibachi 125 monoblocks up for sale here the other day. I used to sell the Advents and have a pair of these and would like to hear them together.

For pure performance, a pair of 100 w/ch or so Class D amps would be another interesting choice. D-sonic might be a good place to look.

FWIW I still have my pair of OHM Ls (refurbed) that I bought back in the 70's when I sold both these and the Advents. OHM L was designed to have Advent sound in a smaller box and still have decent efficiency. These sound really good off my 500w/ch CLas D Bel Canto ref1000m monoblocks that I use to run these and other more demanding speakers, but are probably overkill for older Advents alone.

My pair work nicely with a Rega Mira3. Also great with my Eagle 4.
You can take the Advents up a few notches by replacing internal wiring, connectors, crossover cap, etc. I have improved the already great bass with 4 front to back 1" maple crossbraces and changing out fiberglass insulation. enjoy.
P.S. Cardas Golden Cross speaker cables work great.. at 4 times the cost of the speaker lol!! Got 2 sets of Advents to play with, paid I think 150 or 200 for each pair.

Maybe Hafler? Once upon a time a DH500 drove the heck out of a certain pair of Large Advents - they sort of make a "period pair". There are definitely others that worked (B&K, maybe Carver or Rotel, even Dynaco) so you really don't have to go at the level of Krell et. al.
