INR 10,000 trumps USD 10,000

[prem]

After 3-4 years of experimenting with several amps ranging from INR 10k to INR 10 lakhs, i have finally zeroed in on the INR 10k amp.

It’s the Denon UD M31 which i like best in my system and for my listening tastes.

Yesterday Satyaki had come over for a long listening session. He felt it was the best music session he’s ever had at my place.

So for now my search for an amp ends.

Wow, that is truly awesome

Congrats. This says all about getting to balanced sound, a fascinating synergy of audio gear and personal preferences

In a hobby like audio which is highly subjective, one needs to keep experimenting till one finds what one likes.

For nearly 6-7 years, I kept experimenting with Denon and even though i liked it every time i heard, my brain would not accept that a INR 10000 amp could sound better than a more expensive tube amp.

But in the last week I finally gave in and worked a bit on better ways of connecting the speaker wire to the Denon binding posts and also played around a bit with speaker placement to get the sound to my liking.

I also use Harman kardon AVR amplifier 3550 - similar price range and yours - and the high current punchy sound is good.

David Karmeli introduced me to Denon UD M31. He goes by ddk on whatsbestforum. He uses it with a variety of high end vintage speakers from TAD to Diatone to JBL in his secondary system.

Recently RomytheCat was extremely impressed with it saying the only other amp that did this kind of magic was the original LAMM ML2. He uses it with a Klipsch plus Vitavox combo.

Ken Kessler too spoke of it very highly way back when it was introduced in early 2000. He had demoed it with Wilson Audio

It’s easily available on eBay. Costs like USD 100 - 200, depending on condition. It also has a cd player and tuner built in.

Reminds me of the song "denon denon ka ssath hai, nibhane ko..."

Congrats ! Prem. No matter how many amplifiers you’ve tried over the past few years, Denon has never left your mind. You always find yourself coming back to it and mentioning.

@prem,

I have copy pasted same text in chatGPT and chatGPT replied this response:

That’s actually a very interesting (and quite common) outcome in audio. After long experimentation, many people end up preferring a simpler or cheaper component that matches their speakers, room, and listening taste better. Price does not always equal better sound in a specific system.


Your choice of Denon UD-M31 makes sense for several reasons:

1. Excellent Musical Tuning​

Denon tuned the UD-M31 mini system for musical warmth and smoothness, not just power. Many listeners describe it as:

• Natural midrange
• Smooth treble
• Good vocal reproduction

For long listening sessions, that kind of tuning can be more enjoyable than some expensive amps that sound analytical or aggressive.

2. Power vs Control​

The UD-M31 is only around 2 × 30W, but if your speakers are efficient, it can still sound very dynamic.


Often:

• A well-matched 30W amp can sound better than a 200W amp that doesn’t synergize with the speakers.

3. System Synergy​

You mentioned experimenting with amps up to ₹10 lakhs. In many systems the limiting factors are:

• speaker voicing
• room acoustics
• listening distance
• recording quality

If the amplifier already drives the speakers cleanly, spending more may not improve the sound much.

4. Listening Preference​

Some expensive amplifiers emphasize:

• extreme detail
• sharp imaging
• studio neutrality

But many people prefer:

• musical flow
• relaxed presentation
• strong midrange for vocals

The UD-M31 is known for exactly that.

A Famous Audio Truth​

In audio circles there is a common idea:

“System synergy beats price.”

A ₹10k amp that matches the system perfectly can easily beat a ₹10 lakh amp that doesn’t.

 

[rwnano]

What sort of amplifiers pair well with bass-heavy transmission line speakers please? Any guidance on synergies please

 

[arunlouie]

I remember the same amp was highlighted in another thread or forum. Guess getting praised again. Nice!

Anilpatel, Denon’s strengths are its flow and bass resolution.

Mids are neutral. Tubes add more magic there. The sound is very very open and spacious. You can hear everything in the mix

Many have asked me if it will work in their system. TBH, i have no idea. In the two systems I heard in Bangalore, it was ok. Nothing special. Bass was again exemplary in both these systems.

My guess is this particular Denon needs a highly resolving source and very resolving speakers. Else it may not shine. The amp is almost like a straight wire with no gain. It practically adds nothing.

There are people who have replaced USD 30- 40000 plus amps with this. So go figure.

Grapevine is this amp was designed by Denon for Japan Broadcast sometime in the 70s. When the mini Denon was being launched in early 2000, Denon didn’t have a design of an amp that could fit in that small chassis. So they went back to the design for Japan Broadcast and used that. The later models don’t have the magic.

If you want to buy, get only the UD M30 or the UD M31. Sound wise they are identical. UD M 30 puts out 20 watts and UD M31 puts out 22 watts

Best budget amp

 

[prem]

Let me put it differently. I didn’t settle on this amp because it cost INR 10000. I would have purchased it even if it cost INR 5 lakhs.

IME, very few amps that can beat this, irrespective of price, for the kind of sound i like.

Pricing has nothing to do with sound - the sooner we accept this the better. If you like something, price doesn't matter we'll pay 10000 rupees or 10 lacs.

I'm selling off all my amps and am using a simple 3W 6BM8 DIY amp these days - it has just one signal tube and one rectifier tube. Doesn't get simpler. For the music I listen to, this beats everything else I have heard.

It must be the same with @prem. Sometimes the amp just clicks.

Can it drive the Tannoy with headroom to spare for dynamics ? It is just 3W.

Dont want to post OT in this thread but will just answer - dynamics are great but maximum volume is limited.
