Millennia Media's Ultra-transparent Stereo Parametric Equalizer

Get to know them!

Starting out in the world of audiophile classical recordings, Millennia Media has established a well-deserved reputation for excellence in producing audio equipment for critical applications. Supporting that reputation is the NSEQ-2, a 2-channel, 4-band parametric equalizer that offers the ability to switch between pure Class A all-discrete JFET solid-state operation, or pure Class A all-triode vacuum tube operation at the touch of a button. The NSEQ-2 has only one active stage in the audio signal path, as opposed to common designs that employ anywhere from three to seven active amplifiers in the signal path. The result is greater sonic integrity and purity and heightened musical realism. Did we mention it's transparent? The Millennia Media NSEQ-2 is a great EQ for surgically precise boosts or cuts.

Stereo parametric equalizer with twin topology

The NSEQ-2 is a 2-channel, 4-band parametric equalizer offering fully Class-A operation via discrete JFET transistors or all triode vacuum tubes selectable with the touch of a button. Millennia's innovative new merging of vacuum tube and transistor circuit topologies. A front panel switch selects between a complete vacuum tube parametric equalizer or a fully discrete solid-state parametric equalizer. Both circuit topologies are entirely transformerless, high voltage, 100% Class-A biased, and minimalist in design.

Minimalist circuitry

What is "minimalist?" The NSEQ-2 has only one active stage in the audio signal path. Compare this with common textbook parametric EQ designs employing anywhere from three to seven active amplifiers in the signal path. Fewer amplifier stages mean greater sonic integrity and heightened musical realism. This single amplifier is optimized as an input buffer, EQ amplifier, and output driver. Imagine the musical clarity achieved as precious audio signals are spared from successively colored amplifier stages. It's something you must hear to appreciate. Seasoned audio recording engineers are calling NSEQ the most musically accurate analog EQ available at any price.

Why transformerless?

Most of today's high voltage pro tube gear uses audio transformers. Yet, transformers add coloration to audio signals; coloration may be great for "effect," but it is not conducive to sonic purity. Via innovative design techniques, Millennia avoids audio transformers entirely. Now, the musicality of Class-A vacuum tube equalization can be realized without the unavoidable sonic artifacts common to signal path transformers.

Twin topology

The solid-state aspect of Twin Topology consists of discrete field effect transistor amplifiers. Millennia also provides these J-FET amplifiers as the next generation of 990 (Jensen tm) and 2520 (API tm) plug-in compatible modules. Twin Topology circuitry employs 300 volt, hand selected triode vacuum tubes. To use the vacuum tube EQ, simply press a front panel switch. To use the solid-state EQ, press the switch again. Twin Topology! Both topologies are designed to deliver a musical optimization of their inherent character.

Finest grade components

The NSEQ-2 offers exquisitely designed high voltage Class A amplifiers free of transformer coupling, carefully optimized around the finest grades of passive components (Vishay pots, mil-spec gold switches, Wima and Electrocube capacitors, Neglex OFC audio cabling, silver Teflon power wiring, etc..). One listening test with the NSEQ-2 will immediately confirm that Millennia has once again set precedence in musical reality and sonic transparency.

Offer applies only to single-receipt qualifying purchases. Select manufacturers may require that only the manufacturer’s products qualify towards the minimum purchase amount needed to be eligible for promotional financing. Otherwise, an invoice that meets the minimum purchase amount and contains at least one qualifying manufacturer product is eligible for promotional financing. No interest will be charged on promo purchase balance, and equal monthly payments are required on promo purchase until it is paid in full. The payments equal the amount financed divided by the number of months in the promo period, rounded up to the next whole dollar. These payments may be higher than the payments that would be required if this purchase was a non-promo purchase. During the last month(s) of the promo period the required monthly payment may be reduced due to the prior months’ rounding. Regular account terms apply to non-promo purchases. New Accounts as of 07/31/2025: Purchase APR is 34.99%. Penalty APR is 39.99%. Min Interest Charge is $2. Existing cardholders: See your credit card agreement terms. Subject to credit approval.

Offer applies only to single-receipt qualifying purchases. No interest will be charged on the promo balance if you pay it off, in full, within the promo period. If you do not, interest will be charged on the promo balance from the purchase date. The required minimum monthly payments may or may not pay off the promo balance before the end of the promo period, depending on purchase amount, promo length and payment allocation. Regular account terms apply to non-promo purchases and, after promo period ends, to the promo balance. New Accounts as of 07/31/2025: Purchase APR is 34.99%. Penalty APR is 39.99%. Min Interest Charge is $2. Existing cardholders: See your credit card agreement terms. Subject to credit approval.

The estimated required monthly payment shown which excludes taxes and delivery equals the amount financed divided by the number of months in the promo period, rounded up to the next cent. During the last month(s) of the promo period the required monthly payment may be reduced due to this rounding. These payments apply only with the financing offer shown. If you make these payments by the due date each month, you should pay off this amount financed within the promo period, if it is the only balance you are paying off. If you have other balances on your account, this payment will be added to any other minimum monthly payments.
