WOULD IT BE DUMB TO BUY A MARK LEVINSON NO 23.5

OK here is my 2 cents, bought a 23.5 used about 7 years ago on Audiogon for $2500 I would rather live on the streets before selling it, this amplifier was used for many hours every day always gave me chills. I had it in storage for 2 years due to losing my job I had to relocate to another state for employment. After 2 years in storage I set up my audio gear few weeks latter I got the pop from the left speaker comes and goes (I wonder if this is due to not using the gear for such a long time) so I took my amplifier to Technetron in NYC an authorized Levinson repair shop. All the smaller silver capacitors were replaced and some soldering was done due to age of the system. I spoke with Pyramid and Technetron about this repair before I decided where to go, I was initially going to ship to Pyramid due to their reputation but shipping would have cost me hundreds of dollars so I went local. Let me state, Pyramid and Technetron both told me the big capacitors do not need to be replaced on the 23.5 they last forever, I told them I was willing to pay for the replacement but they insisted I was waisting money, this is coming from technicians that have over 15 years experience repairing Levinson gear, I was surprise cause I would have no problems giving them the money to replace the large capacitors. I am about to go pick up my amplifier in a few hours. I was told after the repair I should get 15 more years of joy with the 23.5 before I would need another repair I was told by the technician that the older Levinson were much better than the newer ones, they were hand made. He told me due to age and heat the boards in the amplifier turned brown he told me not to leave the amplifier on when I was not using it he said some people leave the amp on 24/7, my amplifier was on all day and only turned off before bed. A new amplifier at this level would cost over $12000 I highly doubt you get better sound than the older Levinson.

My gear:
Levinson 23.5 x 2
Levinson 32
Levinson 360S
Dynaudio Confidence 5

I read your post and that made me post mine because we both have the same exact problem lol
I will add one thing for you since we have a close system as well, I had the 380S and upgraded to the 32, its a big step in price but I will never sell my 32 it is the best non tube pre amp PERIOD, if you ever replace the 380 for the 32 I promise you will hear the difference immediately its like a window was opened, I apologize if I gave you the upgrade bug, believe me I have no regret, like many others I can't afford a new system and even at $9800 it was the biggest audio purchase I ever made, no regrets. 

Back from Technetron listening to my system now with a big fat smile on my face. They did an outstanding job, the facility is not large its NYC space, the rooms were narrow, I was worried about scratches and dents but I found nothing they were very careful. They gave me a detail receipt with all parts and labor listed. Overall I received a bag with all the old parts including Resistors, Capacitors and Transistors. It says 14 hours of labor. They adjusted regulator bias, adjusted output and DC voltage and cleaned controls I have 90 days warrenty. I will go back to Technetron for future repairs they had high end equipment over there. In my opinion this is the best way to enjoy high end equipment, buy used at a great price and find a good repair shop. The parts they used are top of the line, all capacitors 105 degree Nichicon. The only negative comment I have is they did not accept credit cards, I could have gotten 2% cash-back lol, no big deal. As stated the amplifier should be good for another 14-15 years. I purchased a second used 23.5 for a low price in mint cosmetic condition it needs repair, going to save up some money and fix the second amp. I am still planning one day on buying the 33H going to save up and find the right pair at a good price that will be my dream system been planning this for many many years.
