Pass INT-25 better than Wilsenton R8?


I have recently purchased a Pass Labs INT-25. It replaced a Wilsenton R8 with NOS tubes (EL-34). I feel that the sound im getting from the Pass is not 5000.00 better. Has anyone purchased a INT-25 and not been blown away from the sound? I do think  that the 25 has a wider soundstage.

@travisg If it is a brand new INT-25, and you do not have 200hrs on it yet, give it time and see if anything changes. I know this is the case with the amps up to ~300hrs.  I'm not as familiar what occurs on integrated units, others may chime in here to validate burn-in / break-in for you. Transformers, caps, and more, let it play.    

@travisg EL34 tubed amps can sound plush compared to a clean/transparent sounding solid state amplifier. Each with its own sound signature and type of presentation.

One other factor you’ll read about is people leaving their pass amps powered on anywhere from 4,8, to ~24hrs before doing any critical listening. Varying debates.

24hrs: Have you tried listening after your INT-25 has been powered on for a full twenty four hours, transformer, all toasty inside? Smoother sounding then?

 

@avanti1960 that's a great example story about the "grilles off / going back on later" to help share differences with others of how sound truly changes from a brand new amp vs. a well broken in amp with 200-300hrs on it. Same story for past 20yrs with many of the pass amps, settling in, transformer warmup before doing critical listening.
