I feel it is time to upgrade my 1977 system.......


I have been enjoying my Pioneer Spec 1 and Pioneer Spec 2 system for a very long time and I have been having issues that have exhausted my patience and nearest shop is 3 hours (each way) from home.  I only listen to my Music Hall TT that pleases me.  My speakers are from 1976 Altec Lansing Model 19 that have been freshend up and I love the sound, I guess because I have been so accustomed to them and I'm sure there are many diff speaker options but for now I wish to continue with the Altec's.  My quest is to replace my amp and preamp.........I have some logistical problems to deal with.  I have ONE!!!! location for new gear, a shelf that is 51 inchs long and 18 inches from a wall to the front edge of the shelf, shelf will handle 200lbs.  My Pioneer amp has ample power and I would like to remain close to the same amout of power.  If you have some ideas for me I would love to hear them.  Not sure how I feel about tube gear since I have no background at all so I (think) I'd rather not go that route, but feel free to change my mind.  Budget not to exceed 18k including cables.  I know there is a wealth of knowledge here unfortunately I have very little to offer so I thank you greatly in advance......

I have Altec Flamencos and recently asked for some advice on amplifiers that you might find helpful. Coincident Frankensteins and Music Reference were recommended for my speakers as well. Also Atmasphere thought that his class d monoblock amps worked well with his similar high efficiency speakers and should be a good pairing for the Altecs. 

 @alexberger gave me the following useful info regarding amplifiers and crossovers:

I have experience with Altec 604E that has similar sensitivity to Altec 846A. In the mid size rooms that I had 200-300 sq feet, 300B SET has enough power. I used McIntosh MC30 monoblocks (30+ watt), Marantz 8B in triode mode (20 watt), and 300B SET (6-7 watt). I also heard 2a3 Boothed monoblocks with my speakers and they were good enough in terms of power. The 30 watt McIntosh MC30 sounded great with my Spendor 2/3 speakers but with super sensitive Altecs it sounded rough and not as natural and refined as a 300B amplifier. 
What is really important is that for a 300B amplifier it has to have a powerful driver tube like 6f6, 6v6 but not popular but weak 6sn7.
The strong power supply with a big and good quality capacitor.
If your room is not huge, I suggest you try Coincident Frankenstein 300b monoblocks or Aric Audio Super 300B SET. Both these amplifiers have powerful driver tubes, interstage transformers and good power supply.

There are a lot of information about crossovers for Altec on Jeff Day page. Jeff prefers Hiraga schematic crossover for his Altec speakers.

I have Altec Valencias (Heathkit 101’s). I bought them because I was curious about the Altec sound. Short story, I love ’em! I alternate them in with my Von Schweikert db99 speakers.

Interesting that the Franks have been brought up in this thread. They are my favorite amps. I use EML XLS 300B tubes. With the Franks, my Altecs disappear with a floor to ceiling, wall to wall, soundstage. Big, realistic, sized images. Images are easy to "see" in front of you. You are there. Wonderful tone, albeit my Altecs can sound a bit strident at very high volumes (over 90db). This is with original 50 year old crossover capacitors that no doubt need to be replaced.

My 1.5 watt per channel SET 45 amps are also very good with my Altecs, but they have a little less flesh on the bones compared to the Franks. It’s nice to switch these in once in awhile.

My OTL monoblocks are just okay, very clear sounding but somewhat analytical.

Each of these amps are very quiet with the Altecs. Low noise floor, no buzz, hum, or hiss.

I acquired the Franks about a month ago and the Music Reference RM9 MKII has been sold to a good home. The Franks have proven to be a better match for the Altec’s, as they allow me to hear deeper into the music.

Hearing deeper into the music. I understand. 👍

Maybe give the Sugden A21 se class A integrated a go...30 watts 8 ohm/40 4 ohm. I'd say that will be plenty of power. Fantastic sounding amp.

Try the Rogue Audio Sphinx v3. Tube front end; solid-state power amp. Easy to afford at $1,700. More power than you'll ever need for your Altecs, It has a rather warm sound itself so it might be too much for your speakers.

Alternatively, I'd look at NAD gear. Good quality; somewhat lean, analytical sound that might work well with your Altecs. And nowhere near $18k.
