Should I repair my Creek 4330 or replace it?

This Music Hall A15 should fit the bill!

Sounds interesting, thanks.

Which model Von Schweikert speakers are you using?

This system I referred to is a secondary system in a small library. Vaulted ceiling, 10’x 14’. Von Schweikert VR-1 speakers with an REL 10” subwoofer. The 5350SE delivers a sweet controlled sound. I could listen to this system all day. The source is either CD or a networked Apple TV playing from my Mac Mini and USB drives in FLAC. DAC is Cambridge DACMagic optical input from the ATV. I call it my Brit system. The 5350SE is a great piece of kit. I’ve had it for many years and still love it. 

Why couldn't HiFi Heavan  find and correct the problem? Twice? I hope they didn't charge you much for their work. I once owned Creek seperates and a 4330 SE. So many pieces have come and gone...I'd say find a shop that could fix for a reasonable amount of money. What repair shops does Creek recommend? 25 yrs old is nothing. Just breaking in! Can't think of too many new pieces of gear I'd buy to replace what you have. I will say the Musical Fidelity M2 si for $569 (Upscale Audio) would merit consideration more so than the Music Hall 15.3 in my mind. Now buying used...5350 SE or an older Arcam Alpha series int. amp. I absolutely love the the musicality/sound my recapped Alpha 10 int. amp makes. Runs hot and has 100w per channel. The extra power sure has a way of improving how your speakers sound. Good Luck!
