Looking for an Amp Replacement


I am in need of advice and direction on replacing my ML 23.5 amp. While replacing the power caps a cap on the output board was damaged and is no longer available. The most viable right now option is to start looking for a replacement amp and to complete repair down the road or scrap it... (was purchased used maybe 10 years ago)

It is for a second system that is mainly used for background and light listening to streamed/internet radio and the occasional CD and playback from NAS storage using JRiver.

Currently have pulled my Perreaux 3150 out of retirement and have been using that with acceptable results. Looking at a used amp for better bang for the buck return in the 150-200wpc and a budget of 2-3k+/-

Rest of system comprises of

ARC ls28, PSA DSD, Magnum Dynalab 801, Shahinian Acoustics Obelisk, Sony XA5400es CD  

I liked the sound I was able to get from this set up with the ML, but have a bad experience with a 333 in main system a while back and as such I do not have a lot of faith in their newer gear.

While not expecting someone to have identical components, would like to hear from tube/ss combos people as I am using this in three systems and really like the overall sound.

If you can’t fix your current amp I’d listen to @mazian above who had your speakers and had good results with a 100Wpc McCormack amp.  Here’s a nice DNA225 that’s 225Wpc and 400 into 4 Ohms.  I’ve got a completely modified DNA 0.5 amp and its got guts and soul, which is probably why mazian liked it with your speakers.

But I’d try to fix your amp first if you like its sound.  You could also contact @bigkidz here as he seems to be able to fix anything and may even improve your sound a bit.  Best of luck in whatever you choose to do.

I am a Pass fanboy so...I have seen 2 Pass Labs 150.5s for ~$3K. THIS one was refurbished by PL before the pandemic. $2900 but offer less and see if seller bites.

The only powerful amp I owned was a McIntosh MC2250.

This is a very clean one:

Published Specs say 250 wpc, mine tested at one of Harvey’s ’McIntosh ’Lab Day’ at 305 wpc within specs. Lab tech told me that was typical for this model.

’Lab Day’.: You scheduled an appointment with a McIntosh tech at Harvey’s on 45th Street, they re-certified your used piece, gave you documentation ....

Lugging that 80 lb beast is an unforgettable experience. It was a gift from a friend in NYC. I pre-scheduled the appt, picked up the amp at 55th and Madison, straight to Harvey’s.

I had a compact rolling cart, like airline people use, amp in a protective bag, strapped to the cart. Couldn’t tell what it was, a big rock perhaps.

Got a cab, little Japanese driver, we got the beast in the trunk together. He looks at me, no words, but a WTF expression. Down 5th Ave, right on 45th Street. Big Sign ’McIntosh’ hanging across the width of the store.

Cab driver sees sign, points at the trunk, says ’McIntosh?'. I say YES, he smiles big time, opens trunk, refuses my help, pulls the monster out by himself, and bows like I was the Emperor.
